Introduction

The Cisco ISE platform is a comprehensive, next-generation, contextually-based access control solution. It offers authenticated network access, profiling, posture, BYOD device onboarding (native supplicant and certificate provisioning), guest management, device administration (TACACS+), and security group access services along with monitoring, reporting, and troubleshooting capabilities on a single physical or virtual appliance. Cisco ISE is available on two physical appliances with different performance characterization, and also as software that can be run on a VMware server. You can add more appliances to a deployment for performance, scale, and resiliency.

Cisco ISE has a scalable architecture that supports standalone and distributed deployments, but with centralized configuration and management. It also allows for configuration and management of distinct personas and services. This feature gives you the ability to create and apply services where they are needed in the network, but still operate the Cisco ISE deployment as a complete and coordinated system.

For more information about the features that are supported in Cisco ISE 2.1, see Cisco Identity Services Engine Admin Guide, Release 2.1.

Ability to Download Core Files and Heap Dumps for Troubleshooting

The show logging CLI command lists the system and application log files. The core files and heap dumps can be listed by using this command. You can now use the copy command to move these files to a repository.

Certificate Page Navigation Changes/Enhancements

The Certificate Authority (CA) Certificates page lists all the certificates related to the internal Cisco ISE CA. In previous releases, these CA certificates were present in the Trusted Certificates store and are now moved to the CA Certificates page. These certificates are listed node wise in this page. You can expand a node to view all the ISE CA certificates of that particular node. The Administration node has the root CA, node CA, subordinate CA, and OCSP responder certificates. The other nodes in the deployment have the node CA, subordinate CA, and OCSP certificates.

Customizable Alarms

You can customize alarms and configure email notifications to be sent to different recipients for each alarm. You can also globally define email recipients who will receive notifications for all alarms configured in the system.

Customizable Dashboard

You can create a new dashboard and add any of the dashlets that you need to the dashboard.

You can customize the tabs, dashlets, and layout. You can drag and drop dashlets, export data from a dashboard as an Excel or PDF file, and provide role-based access control for the dashlets.

Context Visibility

The Context menus display graphical information about endpoints based on a variety of configurable attributes. Endpoint data can be segmented by features, applications, BYOD, and other categories, depending on your license. The Context menus use a central database, gathers information from database tables, caches, and buffers, which makes updates to context dashlets and list content very fast. You can use controls on context visibility pages to filter the data that is displayed, and by applying multiple filters, progressively narrow the displayed data for particular endpoints.

Easy Connect

Easy Connect enables you to easily connect users from a Windows based endpoint to a network in a secured manner and monitor those users by authenticating them through an Active Directory (AD) Domain Controller (DC) and not by Cisco ISE. With Easy Connect, Cisco ISE collects user authentication information from the Active Directory (AD) Domain Controller. With Easy Connect, Cisco ISE issues a CoA (change of authorization) to the network access device (NAD) after the user is authenticated by Active Directory. Authenticated users are then shown in the Cisco ISE live sessions view, and can be queried from the session directory.

Enable or Disable IPv6 on Each Interface

This release of Cisco ISE provides an option from the CLI to enable or disable IPv6 at the interface level.

Feed Service Enhancements

If you are unable to connect the Cisco ISE deployment to the Cisco feed service, you can download the profiler policies and OUI updates offline and import them to the Cisco ISE Primary Administration Node using an offline feed update.

Google Chromebook Onboarding Support

Support for onboarding of managed Chromebook devices on a corporate network. Chromebook devices must download the Cisco Network Setup Assistant extension from the Chrome Web Store to start the onboarding process.

Note Cisco ISE supports onboarding of Chromebook devices that are managed by Google console. Unmanaged Chromebook devices are not supported.

Guest Enhancements

Support for SMS Proxy —Guest now supports SMS text through a proxy. The SMS gateway provides HTTP API access to SMS providers, and uses a proxy if a proxy server is defined in Administration > System > Proxy.

From First Logon —A Guest Type can be configured to start a user’s account duration when that user logs on. This allows a sponsor to create and distribute logon credentials ahead of time, instead of as people arrive for a meeting.

New SAML Server support —Cisco ISE end-user web portals now support PingIdentity (Cloud), PingFederate (CPE), Azure Active Directory, SecureAuth, and servers running generic SAML 2.0.

Single portal for credentialed and SAML SSO login —The login portal can be configured to provide the option to log in with credentials, or to click a link that redirects the user to an SSO portal page. The link that the user clicks to redirect to an SSO provider can be customized.

Sponsor Approval Filtering —A sponsor can be limited to approving accounts based on the sponsor’s email address, or all pending accounts. Currently this feature is supported only for internal sponsors and SAML SSO sponsors.

Workcenter menu —The Guest menu has been removed, and all the options related to Guest portal are listed under the Guest heading under Work Centers.

Shorter default username and password —The guest default username is four alpabetic and password is four numeric characters. Short, easy to remember usernames and passwords are adequate for short-term guests. You can change the username and password length in ISE, if you desire.

IP SGT Mapping and Mapping Groups

While adding an IP SGT static mapping, you can use an existing mapping group or map the IP address/hostname to a SGT individually and specify the SXP VPN groups and target devices.

You can import or export the IP SGT static mappings.

While adding a mapping group, you can select the SGT and specify the SXP VPN groups and the devices on which the mappings must be deployed.

Livelog Page Enhancements

You can do the following in the RADIUS, TACACS, and RADIUS Sessions Live Logs page:

Hide all or some columns
Change column width
Change the order of columns
Filter the data by time range, number of records, refresh interval and also set quick and advanced filters

Persistent Machine Access Restriction (MAR) Cache

Cisco ISE stores the MAR cache content, calling-station-ID list, and the corresponding time stamps to a file on its local disk when you manually stop the Cisco ISE application services. Cisco ISE does not store the MAR cache entries of an instance when there is an accidental restart of its application services.

Cisco ISE reads the MAR cache entries from the file on its local disk based on the cache entry time to live when the Cisco ISE application services get restarted. When the run-time services of an Cisco ISE instance come up after a restart, Cisco ISE compares the current time of that instance with the MAR cache entry time. If the difference between the current time and the MAR entry time is greater than the MAR cache entry time to live, then Cisco ISE does not retrieve that entry from disk. Otherwise, Cisco ISE retrieves that MAR cache entry and updates its MAR cache entry time to live.

MDM Enhancements

Cisco ISE now supports Microsoft Intune and Microsoft SCCM as external MDM servers. The following versions of SCCM are supported with this release:

– Windows 2008 R2 and SCCM 2008 R2

– Windows 2012 R2 and SCCM 2012 R2

Attributes from MDM servers can now be published to pxGrid.

Time Interval For Compliance Device ReAuth Query

When the endpoint is authenticated or re-authenticated, ISE uses a cache to get the MDM variables for that endpoint. If the age of cached value is older than the value of Time Interval For Compliance Device ReAuth Query, then ISE makes a device query to the MDM server to get new values. If the compliance status changed, then ISE triggers a CoA. The valid range is from 1 to 1440 minutes. The default value is 1 minute.

Note This feature is introduced as a part of Release 2.1 Patch 4.

NIC Bonding for High Availability

Cisco ISE supports bonding of two Ethernet interfaces into a single virtual interface to provide high availability for the physical interfaces. The NIC bonding feature in Cisco ISE does not support load balancing or link aggregation features. The bonding of interfaces ensures that Cisco ISE services are not affected when there is:

Physical interface failure
Loss of switch port connectivity (shut or failure)
Switch line card failure

ODBC Identity Source

Cisco ISE supports Open Database Connectivity (ODBC)-compliant relational databases. The following database engines are supported:

Microsoft SQL Server
Oracle
PostgreSQL
Sybase

ODBC identity source can be used in an identity store sequence and for Guest and Sponsor authentications. It can also be used for BYOD flow.

You must configure the required stored procedures to authenticate users against an ODBC identity source. The values that are returned and the tasks that are required of the stored procedure vary based on the authentication protocol used.

While adding an ODBC identity source, you can also add the required attributes and user groups. Cisco ISE allows you to fetch the attributes and user groups from ODBC database. You can use these attributes and user groups in the authorization policies.

Option to View the Process and Thread Utilization in Cisco ISE

A new CLI command, show cpu usage, is introduced in this release. This command lists the CPU usage for each component such as policy services, PSC, profiler, TACACS+, and so on.

Posture Enhancements

Anti-malware condition to check the installation of an anti-malware program on the client and to check if the latest anti-malware definition file of the selected vendor is updated on the client. It supports both MAC and Windows OS.
USB mass storage Cisco predefined condition to check if a USB mass storage device is connected to an endpoint.
OESIS version 4 to check and remediate endpoint compliance.

Profiler Enhancements

Profiler related options are grouped under the Profiler Work Center menu (Work Centers > Profiler), so that the administrator can easily access all the options related to Profiling service at one location.
Supports the NMAP scan action to run the SMB discovery script that is provided by NMAP.
Identifies the services running on an endpoint using the service version information probe.
Allows the use of custom ports for automatic and manual NMAP scan actions.
Skips the NMAP host discovery of known endpoints.
Profiles endpoints that are running McAfee agents as corporate devices, by using the McAfee ePolicy Orchestrator (McAfee ePO) security management software. Cisco ISE provides an in-built NMAP scan action (MCAFeeEPOOrchestratorClientscan) to check if the McAfee agent is running on an endpoint using NMAP McAfee script on the configured port.
Provides the Active Directory probe to improve the fidelity of OS information for Windows endpoints.
Allows the export of probe data from the GUI.
Facilitates the offline update of feed services when Cisco ISE is not directly connected to the Cisco feed server.

pxGrid Certificate Template for the Internal Cisco ISE CA

To deploy pxGrid service easily, Cisco ISE provides a certificate template that signs an end entity's CSR and has the client and server EKUs on the certificate. From the Certificate Provisioning Portal, you can paste the CSR text from the pxGrid client and sign the keys using the pxGrid template. Cisco ISE nodes can also use this function for pxGrid certificates. As a Cisco ISE administrator, you can revoke the pxGrid certificates.

pxGrid Client Authentication Settings

You can enable username/password based authentication for pxGrid clients. A pxGrid client can register itself with the pxGrid controller by sending the username via REST API. The pxGrid controller generates a password for the pxGrid client during client registration. The administrator can approve or deny the connection request.

Report List for Work Centers

Reports that are tagged for different work centers appear in the Reports menu under each Work Center.

SAML Identity Source Enhancements

Cisco ISE is SAMLv2 compliant and supports all SAMLv2 compliant IdPs that use Base64-encoded certificates. The IdPs listed below have been tested with Cisco ISE:

Oracle Access Manager (OAM)
Oracle Identity Federation (OIF)
SecureAuth
PingOne
PingFederate
Azure Active Directory

SAML SSO is supported for Guest, Sponsor, My devices, and Certificate Provisioning portal.

You can add a load balancer in front of Cisco ISE nodes to simplify the configuration on the Identity Provider side and optimize the load on ISE nodes.

While adding an IdP, you can add the attributes and user groups. These attributes and user groups can be used in the authorization policies. You can configure the Identity attribute and logout settings in the Advanced Settings tab.

SAML Signing Certificate

From the System Certificates page of the Admin Portal, you can set up a certificate for SAML signing use. SAML certificate can be a wildcard or non-wildcard certificate. SAML certificate is replicated to all the nodes in the deployment.

SAML SSO Support for Certificate Provisioning Portal

While configuring the Certificate Provisioning Portal settings in the Admin portal, you can now select an identity provider such as Oracle Access Manager as an external identity store to allow for single sign on across all Cisco ISE end user portals. When an IdP user launches the Certificate Provisioning Portal, the user is redirected to the IdP login page for authentication. If authentication is successful, the user is redirected back to the Certificate Provisioning Portal.

Reports and audit logs include information about users logging in via the SAML SSO as well as other identity sources.

Smart Licensing

Cisco offers Smart Licensing, which enable you to monitor ISE software licenses and endpoint license consumption easily and efficiently. When Smart Licensing is activated from Cisco ISE, it monitors the consumption of licenses and notifies the administrator about the license usage. When licenses are available and not consumed, the administrator is notified of available licenses. When consumption exceeds the amount of licenses available, an alarm is activated and the administrator is notified through alarms and notifications.

When Smart Licensing is activated, the Smart Call Home (SCH) feature is enabled by default. This feature monitors Cisco ISE devices in your network and notifies you via e-mail about critical events. It also provides real-time alerts with remediation advice for issues that are detected. SCH monitors and sends event notifications for configuration, inventory, Telemetry, crash, hardware, and environment issues.

The Anonymous Reporting feature of SCH provides minimal health information about the Cisco ISE devices in your network.

You can choose to enable only Anonymous Reporting or enable the full set of features offered by SCH.

Support for Elliptical Curve Cryptography (ECC) Certificates

Cisco ISE CA service now supports client side certificates based on Elliptical Curve Cryptography (ECC) algorithms. ECC offers increased security and better performance than other cryptographic algorithms while providing the same level of security as other systems with a much smaller key size.

Cisco ISE CA service supports ECC certificates for devices connecting through the BYOD flow. You can also generate ECC certificates from the Certificate Provisioning Portal.

If the BYOD flow with Enrollment over Secure Transport (EST) protocol is not working properly, check the following:

Certificate Services Endpoint Sub CA certificate chain is complete. To check whether the certificate chain is complete:

1. Choose Administration > System > Certificates > Certificate Authority > Certificate Authority Certificates.

2. Check the check box next to the certificate that you want to check, and then click View.

Ensure that the CA and EST services are up and running. If the services are not enabled, go to Administration > System > Certificates > Certificate Authority > Internal CA Settings to enable the CA service.

Note This release of Cisco ISE does not support EST clients to authenticate directly against the EST server that resides in Cisco ISE.
When an Android or Windows endpoint onboards and the request is for an ECC-based certificate, an EST flow is triggered internally within Cisco ISE.

If you have upgraded to Cisco ISE 2.1 from an ISE version prior to 2.0, replace the ISE Root CA certificate chain after the upgrade. To do this:

1. Choose Administration > System > Certificates > Certificate Management > Certificate Signing Requests.

2. Click Generate Certificate Signing Requests (CSR).

3. Choose ISE Root CA from the Certificate(s) will be used for drop-down list.

4. Click Replace ISE Root CA Certificate Chain.

The following table lists the operating systems and versions that support ECC along with the curve types that are supported. If your devices are not running a supported operating system or on a supported version, you can use RSA-based certificates instead.

Supported Versions
Windows	8 and later	P-256, P-384, and P-512
Android	4.4 and later Note Android 6.0 requires May 2016 patch to support ECC certificates.	All curve types (except Android 6.0, which does not support the P-192 curve type).

Supported Versions

Windows

8 and later

P-256, P-384, and P-512

Android

4.4 and later

Note Android 6.0 requires May 2016 patch to support ECC certificates.

All curve types (except Android 6.0, which does not support the P-192 curve type).

Note Windows 7 and Apple iOS do not natively support ECC for EAP-TLS authentication. This release of Cisco ISE does not support the use of ECC certificates on MAC OS X devices.

Support for SNMP Traps

SNMP traps help you to monitor the status of Cisco ISE processes. Without accessing the Cisco ISE server, if you want to monitor the Cisco ISE processes, you can configure a MIB browser as an SNMP host in Cisco ISE. You can then monitor the status of Cisco ISE processes from the MIB browser.

TACACS+ Device Administration Enhancements

The Device Administration Deployment page lists the PSNs in your deployment and allows you to centrally view the device administration system without referring to each node in the deployment section. You can collectively enable the device admin service for multiple PSNs.
New fields such as Shared Secret and Retire Shared Secret have been included in the TACACS authentication settings to authenticate users.
Support for authentication protocol services, such as PAP/ASCII, CHAP, and MS-CHAPv1, in FIPS and non-FIPS modes.
Support for new common task types such as Shell, WLC, Nexus, and Generic.
The TACACS Ports field allows you to configure a maximum of four TCP ports using which Cisco ISE nodes and their interfaces listen for TACACS+ requests.

Third-Party Device Support Enhancements

If a device supports neither dynamic nor static URL redirect, Cisco ISE provides an Auth VLAN by which it simulates URL redirect. Auth VLAN is based on unique DHCP/DNS server attributes you define in ISE.

Additionally, SNMP-based Change of Authorization (CoA) support has been added to support network access devices that lack support for RADIUS CoA.

If you enable the ACL (Filter-ID) option while creating an authorization profile, Cisco ISE does not appends '.in' to the ACL for non-Cisco devices. By default,'.in' is appended to the ACL for Cisco devices. When you upgrade to Cisco ISE 2.1 from an earlier release, '.in' is not appended to ACL for non-Cisco devices.

Cisco ISE 2.1 has been tested with the vendor devices listed in the following table:

Table 1 Vendor Devices Tested With Cisco ISE 2.1
Vendor	URL Redirect Type
Vendor	URL Redirect Type	802.1X / MAB	Profiler with CoA	Guest/ BYOD
Wireless	Aruba 7000, InstantAP	RADIUS	Static URL	√	√	√	√	√
	Motorola RFS 4000	RADIUS	Dynamic URL	√	√	√	√	√

	Brocade ICX 6610¹	RADIUS	Auth VLAN provided by ISE	√	√	√	√	√
	Juniper EX3300-24p	RADIUS	Auth VLAN provided by ISE	√	√	√	√	√
For additional third-party NADs, you must identify the device properties and capabilities and create custom NAD profiles in Cisco ISE.				√	√	Requires CoA support	Requires CoA support. For URL redirect, if the wired device has no URL redirect, utilizes Cisco ISE Auth VLAN. Wireless devices have not been tested with Auth VLAN.

^1.Brocade switch (ICX6610-24 SW: Version 08.0.20aT7f3) requires a session ID to send a Change of Authorization (CoA) request. Advanced flows such as BYOD, Guest, and Posture using MAB authentication do not work properly because accouting information and session ID are not collected and hence Change of Authorization (CoA) cannot be issued.

Note In Cisco ISE, a session cannot be created in the session cache when Network Access Device does not send calling station ID in the Access-Request. As a result, scenarios which relies on the session attribute lookup like guest, posture, BYOD are currently not supported with such network access devices.

Threat-Centric NAC

Threat Centric Network Access Control (TC-NAC) feature enables you to create authorization policies based on the threat and vulnerability attributes received from the threat and vulnerability adapters. Threat severity levels and vulnerability assessment results can be used to dynamically control the access level of an endpoint or a user.

You can configure the vulnerability and threat adapters to send high fidelity Indications of Compromise (IoC), Threat Detected events, and CVSS scores to Cisco ISE, so that threat-centric access policies can be created to change the privilege and context of an endpoint accordingly.

Cisco ISE supports the following adapters:

SourceFire FireAMP
Qualys

Note Only the Qualys Enterprise Edition is currently supported for TC-NAC flows.

TrustSec ACI Integration

Cisco ISE allows you to synchronize SGTs and SXP mappings with the Internal Endpoint Groups (IEPGs), External Endpoint Groups (EEPGs), and endpoint (EP) configuration of Cisco Application Centric Infrastructure (ACI).

Cisco ISE supports packets coming from the ACI domain to the TrustSec domain by synchronizing the IEPGs and creating correlating read-only SGTs in ISE. These SGTs are used to map the endpoints configured in ACI and create correlating SXP mappings in ISE. These SGTs are displayed on the Security Groups page (with the value 'ACI' in the Learned From field). You can view the SXP mappings on the All SXP Mappings page.

ACI supports the packets coming from the TrustSec domain to the ACI domain by synchronizing the SGTs and creating correlating EEPGs.

TrustSec Matrix Workflow Process

The Matrix Workflow feature provides the ability to roll out new policy in a phased manner. A new policy is created as the staging matrix. This feature includes an approval workflow, where the staging policy cannot be deployed until it is approved. After approval, the staging matrix can be deployed on a limited set of devices. This is useful for evaluating the policy before full deployment. The staging matrix can be edited, if required. The deployment can continue on to the next set of devices or to all devices. Once the staging matrix is fully deployed, the staging matrix can be set as the new production matrix.

TrustSec Matrix Enhancements

Cisco ISE allows you to import and export the egress policy in CSV format. You can export the file to a local drive or a remote repository. The exported file can be encrypted by using an encryption key.

You can include the empty cells (which do not have any SGACL configured) in the exported file. When this option is enabled, the whole matrix is exported and the empty cells are marked with the “Empty” keyword in the SGACL column.

While importing the egress policy, you can overwrite the existing policy with the one that you are importing. If empty cells are included in the imported file, the existing policy in the corresponding matrix cells will be deleted.

Upgrading to Release 2.1

You can directly upgrade to Release 2.1 from the following Cisco ISE releases:

1.3
1.4
2.0
2.0.1

This release of Cisco ISE supports GUI as well as CLI based upgrade.

Note If you have installed a hot patch, roll back the hot patch before applying an upgrade patch.

GUI-Based Upgrade

The GUI-based upgrade from the Admin portal is supported only if you are currently on Release 2.0 and want to upgrade to Release 2.1.

CLI-Based Upgrade

From the Cisco ISE CLI, you can upgrade from Release 1.3, 1.4, and 2.0 directly to Release 2.1.

Virtual Machine Settings - Support for Red Hat Enterprise Linux 7

If you are upgrading Cisco ISE nodes on virtual machines, ensure that you change the Guest Operating System to Red Hat Enterprise Linux (RHEL) 7. To do this, you must power down the VM, change the Guest Operating System to RHEL 7, and power on the VM after the change.

Note If you are installing Cisco ISE on an ESXi 5.x server, to support RHEL 7 as the Guest OS, update the VMware hardware version to 9 or later. RHEL 7 is supported with VMware hardware version 9 and later.

Refer to the Cisco ISE Upgrade Guide, Release 2.1 for a list of pre and post upgrade tasks.

Note When you upgrade to Cisco ISE, Release 2.1, you may be required to open network ports that were not used in previous releases of Cisco ISE. For more information, see Cisco ISE Ports Reference in the Cisco Identity Services Engine Hardware Installation Guide, Release 2.1.

Upgrade Considerations and Requirements

Read the following sections before you upgrade to Cisco ISE, Release 2.1:

SSL Exceptions in Elasticsearch.log File
Upgrade to Release 2.1 Restores Old Guest Accounts
Hostname Corruption in Elastic Search Configuration Files
Reverse DNS Lookup Configuration
Firewall Ports That Must be Open for Communication
Disable Backup Before You Upgrade
Admin User Unable to Access the ISE Login Page Post Upgrade
Rename Active Directory Join Point Name if the Join Point Name is ActiveDirectory
Rejoin Cisco ISE with Active Directory
Update Authorization Policies for New Guest Types
Other Known Upgrade Considerations and Issues

SSL Exceptions in Elasticsearch.log File

The Visibility and Context Service in Cisco ISE uses the Elastic search engine to filter records. The SSL exception on Elastic search results in an “Internal server error” in the Endpoints page. Three different types of SSL exceptions appear in the elasticsearch.log file:

Certificate unknown issue can be seen in the elasticsearch.log file. As a workaround, confirm that the certificate PAN is using is correct. If CA certificate and admin certificate are not installed, reapply them for primary PAN after the upgrade
Null certificate chain issue is seen in the elasticsearch.log file : This issue occurs when the ISE admin certificate chain is missing from the Elastic search key store. As a workaround, add the entire certificate chain of ISE admin certificate to the Elastic search key store and restart application services.
No subject alternative names present : This issue appears when the Cisco ISE Admin certificate does not include the IP address in the SAN field of the certificate. As a workaround, generate a self-signed certificate or obtain a CA-signed certificate for Admin use with the IP address in the SAN field for both the Primary and Secondary Administration nodes in the deployment.

Upgrade to Release 2.1 Restores Old Guest Accounts

If you have From First Login guest type accounts created in Release 1.2, the accounts that were never used or is still active are migrated to Release 2.1. If you no longer need these accounts, you can delete them manually from the Sponsor portal.

Hostname Corruption in Elastic Search Configuration Files

This issue occurs when you have duplicate host entries in the /etc/hosts file and you might run in to deployment-related issues after upgrade (ISE Indexing Engine status turns to “not running”). As a workaround, remove the duplicate host entries with root, and restart Cisco ISE services.

Reverse DNS Lookup Configuration

Configure reverse DNS lookup for all Cisco ISE nodes in your distributed deployment in the DNS server(s). Otherwise, you may run into deployment-related issues after upgrade (“ISE Indexing Engine” status turns to “not running”).

Also, the secondary PAN is unable to join the primary PAN to make a cluster for ISE Indexing engine if reverse DNS is not configured, displays error in VCS pages.

The SSL Exception “No subject alternative name present” displays on secondary PAN on the ise-elasticsearch.log file, if reverse DNS is missing.

Firewall Ports That Must be Open for Communication

If you have deployed a firewall between the primary Administration node and any other node, the following ports must be open before you upgrade to Release 2.1:

TCP 1521—For communication between the primary administration node and monitoring nodes.
TCP 443—For communication between the primary administration node and all other secondary nodes.
TCP 12001—For global cluster replication.
TCP 7800 and 7802—(Applicable only if the policy service nodes are part of a node group) For PSN group clustering.

For a full list of ports that Cisco ISE, Release 2.1 uses, refer to Cisco ISE Ports Reference in the Cisco Identity Services Engine Hardware Installation Guide, Release 2.1.

Disable Backup Before You Upgrade

Cisco ISE does not support deployment changes when a backup is in progress. Plan your deployment upgrade in such a way that you reschedule the backups after the upgrade. You can choose to disable the backup schedules and recreate them after upgrade to Release 2.1.

Backups with a schedule frequency of once get triggered every time the Cisco ISE application is restarted. Hence, if you have a backup schedule that was configured to run just once, be sure to disable it before upgrade.

Admin User Unable to Access the ISE Login Page Post Upgrade

If you had enabled certificate-based authentication for administrative access to Cisco ISE (Administration > Admin Access) before upgrade and used Active Directory as your identity source, after upgrade, you will not be able to launch the ISE Login page because Active Directory join is lost during upgrade.

Workaround

From the Cisco ISE CLI, start the ISE application in safe mode using the following command:

application start ise safe

This command brings up the Cisco ISE node in safe mode and you can use the internal admin user credentials to log in to the ISE GUI.

After you log in, you can join ISE with Active Directory.

Rename Active Directory Join Point Name if the Join Point Name is ActiveDirectory

Before you upgrade to Release 2.1, if the Active Directory join point name is called “ActiveDirectory,” this might cause database corruption and RADIUS requests might be dropped after upgrade.

As a workaround, before you upgrade to Release 2.1, change the Active Directory join point name to something other than “ActiveDirectory.” For example, ActiveDirectory1. You don’t have to rename the join point name again after upgrade.

Rejoin Cisco ISE with Active Directory

Ensure that you have the Active Directory credentials if you are using Active Directory as your external identity source. After an upgrade, you might lose Active Directory connections. If this happens, you must rejoin Cisco ISE with Active Directory. After rejoining, perform the external identity source call flows to ensure the connection.

Update Authorization Policies for New Guest Types

After upgrading to Cisco ISE 2.1, the new guest types that are created do not match the upgraded authorization policies. You need to make sure that the authorization policies are updated with the new guest types.

Other Known Upgrade Considerations and Issues

This section provides a list of known upgrade-related caveats. See Cisco ISE, Release 2.1 Open Caveats for a description of these caveats and for fixes in patch releases, if available.

Refer to the Cisco Identity Services Engine Upgrade Guide, Release 2.1 for other known upgrade considerations and issues.

Cisco Secure ACS to Cisco ISE Migration

You can directly migrate to Cisco ISE, Release 2.1 only from Cisco Secure ACS, Releases 5.5 and later. For information about migrating from Cisco Secure ACS, Releases 5.5 and later to Cisco ISE, Release 2.1, see the Cisco Identity Services Engine Migration Tool Guide.

You cannot migrate to Release 2.1 from Cisco Secure ACS 5.1, 5.2, 5.3, 5.4, 4.x, or earlier versions, or from Cisco Network Admission Control (NAC) Appliance. From Cisco Secure ACS, Releases 4.x, 5.1, 5.2, 5.3, or 5.4, you must upgrade to ACS, Release 5.5 or 5.6, and then migrate to Cisco ISE, Release 2.1.

Note If you are installing Cisco ISE, Release 2.1 on Cisco SNS-3500 series appliances with ACS PIDs (Cisco SNS-3515-ACS-K9 and Cisco SNS-3595-ACS-K9), you must update the BIOS and CIMC firmware on the hardware appliance before you install Cisco ISE, Release 2.1. Refer to the Cisco Identity Services Engine Hardware Installation Guide for information on how to update the BIOS and CIMC firmware.

Known Limitations in Cisco ISE, Release 2.1

This section lists known limitations in Release 2.1:

High Memory Utilization
Diffie-Hellman Minimum Key Length
SXP Protocol Security Standards
System and Trusted Certificates With Duplicate Extensions Do Not Allow ISE Services to Start
LDAP Sponsor Created Guest Users Not Visible When Upgraded From 1.2
LDAP Imported Guest Accounts Not Upgraded From Version 1.2
Do Not Delete the Default Internal Cisco ISE CA Templates
Do not Install a Patch Until Upgrade
TLS Authentication on Android Devices Does Not Use Certificates Issued by the Assigned Certificate Authority
EKU Validation: OCSP Signing Certificate Returns Unknown for Root CA
Backup and Restore Page Takes a Long Time to Load
EST Service Does Not Run in Cisco ISE 2.1
Profiler RADIUS Probe

High Memory Utilization

Cisco ISE Version 1.3 and later use RHEL, version 6. You may experience high memory utilization after installing or upgrading to Cisco ISE Version 1.3 or later. However, this does not negatively impact Cisco ISE performance and there are no alarms that are triggered. In case, if the memory usage is consistently above 90% or if there is any performance impact, you can contact Cisco TAC for troubleshooting.

Diffie-Hellman Minimum Key Length

Connection to LDAP server will fail if the Diffie-Hellman minimum key length configured on the LDAP server is less than 1024.

SXP Protocol Security Standards

SXP protocol transfers unencrypted data and uses weak hash algorithm for message integrity checking per draft-smith-kandula-sxp-06.

SXP service must be enabled on a dedicated node

SXP service must be enabled on a dedicated node. If both Passive Identity and SXP service are enabled on the same node, static SXP mappings are not added to the SXP table and the ise-psc log shows ClassCastExceptions warnings.

System and Trusted Certificates With Duplicate Extensions Do Not Allow ISE Services to Start

An X.509 certificate has an extension field that you can use to add additional fields to the certificate. For example, basicConstraints, Key Usage, etc. A certificate can include only one instance of a particular extension.

If a certificate in the Cisco ISE System or Trusted Certificates Store has more than one instance of a particular extension, the ISE application services do not start when the system is restarted.

Workaround: Contact Cisco Technical Assistance Center (TAC) to remove the certificate from the database.

LDAP Imported Guest Accounts Not Upgraded From Version 1.2

Guests that were imported by an LDAP authenticated sponsor in version 1.2 will not be migrated during an upgrade to 1.3, 1.4, 2.0, or 2.1.

LDAP Sponsor Created Guest Users Not Visible When Upgraded From 1.2

When upgrading from 1.2 to 1.3, 1.4, 2.0, or 2.1, guests who were created by a sponsor who was authenticated through LDAP can only be seen by the direct sponsor. These guests cannot be seen by other sponsors from the same sponsor group.

Do Not Delete the Default Internal Cisco ISE CA Templates

The internal Cisco ISE CA comes with two default certificate templates:

CA_SERVICE_Certificate_Template—Cisco ISE uses this template to issue certificates when other network services use Cisco ISE as the CA. For example, for client machines that connect over ASA VPN.
EAP_Authentication_Certificate_Template—Cisco ISE issues certificates for EAP authentication based on this template.

Do not delete these default certificate templates. If you want to customize the certificate template, you can create a new one, or copy an existing template and edit it.

Do not Install a Patch Until Upgrade

When upgrade is in progress, do not install a patch on any node in the deployment simultaneously. Patch installation should be done after deployment upgrade is complete.

TLS Authentication on Android Devices Does Not Use Certificates Issued by the Assigned Certificate Authority

This issue occurs when you have configured:

Internal and external Certificate Authority (CA) in Cisco ISE.
Two profiles (SSID1 and SSID2) for TLS authentication using the internal and external CA, respectively.

The certificates provisioned from Cisco ISE are imported in to the Android certificate store. Sometimes, the wireless networks use one of the many certificates when connecting to the network. For example, when an Android device connects to the network using SSID 1, the certificate used for authentication is issued by the internal CA. When a second Android device connects using SSID 2, the certificate used for authentication is again issued by the internal CA instead of the external CA (as configured in SSID2).

This issue is seen only in Android devices and there is no workaround.

Cisco recommends that you update your Android device with all fixes and upgrades offered by the vendor.

EKU Validation: OCSP Signing Certificate Returns Unknown for Root CA

The Bouncy Castle OCSP signing certificate returns an 'unknown' response for the Root CA. If you have configured Cisco ISE to reject requests when an unknown certificate status is returned by the OCSP service, Cisco ISE rejects the certificate that is being evaluated and the user authentication fails.

This issue is seen in Bouncy Castle, version 1.6.145-generated certificates. There is no workaround.

Backup and Restore Page Takes a Long Time to Load

This issue occurs if the “Admin” certificate is configured with CRL check and the CRL server URL is not reachable from Cisco ISE.

As a workaround, you can do one of the following:

Ensure that the CRL server is reachable from Cisco ISE.
Generate a new “Admin” certificate without CRL check.
Generate a self-signed certificate for Admin usage.

EST Service Does Not Run in Cisco ISE 2.1

After a fresh installation of Cisco ISE 2.1, when you run the show application status ise command, the EST service might be shown as disabled. This issue occurs when the root certificate of the Cisco ISE internal CA is signed by an external CA and the external CA certificate is not present in your Trusted Certificates store. Import the external CA certificate in to the Trusted Certificates store to bring up the EST service.

This issue is also seen after upgrade to Release 2.1, if the entire certificate chain of the internal ISE CA is not present. You must generate the Cisco ISE CA chain to bring up the EST service.

Profiler RADIUS Probe

When the RADIUS probe is disabled, endpoints are not profiled but are only authenticated and added to the database.

Features Not Supported in Cisco ISE, Release 2.1

IPN / iPEP configuration is not supported with Cisco ISE, Release 2.0 and later.
You cannot access the Operations menu from the primary Monitoring node in Cisco ISE, Release 2.1; it appears only in the Primary Administration Node (PAN).

Cisco ISE License Information

Cisco ISE licensing provides the ability to manage the application features and access, such as the number of concurrent endpoints that can use Cisco ISE network resources.

All Cisco ISE appliances are supplied with a 90-day Evaluation license. To continue to use Cisco ISE services after the 90-day Evaluation license expires, and to support more than 100 concurrent endpoints on the network, you must obtain and register Base licenses for the number of concurrent users on your system. If you require additional functionality, you will need Plus and/or Apex licenses to enable that functionality.

Cisco ISE, Release 2.1, supports licenses with two UIDs. You can obtain a license based on the UIDs of both the primary and secondary Administration nodes.

For more detailed information on license types and obtaining licenses for Cisco ISE, see the “Cisco ISE Licenses” chapter in the Cisco Identity Services Engine Administration Guide, Release 2.1.

For more information on Cisco ISE, Release 2.1 licenses, see the Cisco Identity Services Engine (ISE) Data Sheet.

Deployment Terminology, Node Types, and Personas

Cisco ISE provides a scalable architecture that supports both standalone and distributed deployments.

Table 4 Cisco ISE Deployment Terminology
Description
Service	Specific feature that a persona provides such as network access, profiler, posture, security group access, and monitoring.
Node	Individual instance that runs the Cisco ISE software. Cisco ISE is available as an appliance and also as software that can be run on a VMware server. Each instance (either running on a Cisco ISE appliance or on a VMware server) that runs the Cisco ISE software is called a node.
Persona	Determines the services provided by a node. A Cisco ISE node can assume any or all of the following personas: Administration, Policy Service, and Monitoring.
Deployment Model	Determines if your deployment is a standalone, high availability in standalone (a basic two-node deployment), or distributed deployment.

Types of Nodes and Personas

A Cisco ISE network has the following types of nodes:

Cisco ISE node, which can assume any of the following personas:

– Administration—Allows you to perform all administrative operations for Cisco ISE. It handles all system-related configurations related to functionality such as authentication, authorization, auditing, and so on. In a distributed environment, you can have one or a maximum of two nodes running the Administration persona and configured as a primary and secondary pair. If the primary Administration node goes down, you have to manually promote the secondary Administration node. There is no automatic failover for the Administration persona.

– Policy Service—Provides network access, posturing, BYOD device onboarding (native supplicant and certificate provisioning), guest access, and profiling services. This persona evaluates the policies and makes all the decisions. You can have more than one node assuming this persona. Typically, there is more than one Policy Service persona in a distributed deployment. All Policy Service personas that reside behind a load balancer can be grouped together to form a node group. If one of the nodes in a node group fails, the other nodes in that group process the requests of the node that has failed, thereby providing high availability.

Note SXP service must be enabled on a dedicated node.

– Monitoring—Enables Cisco ISE to function as a log collector and store log messages from all the Administration and Policy Service personas on the Cisco ISE nodes in your network. This persona provides advanced monitoring and troubleshooting tools that you can use to effectively manage your network and resources.

A node with this persona aggregates and correlates the data that it collects to provide meaningful reports. Cisco ISE allows a maximum of two nodes with this persona that can assume primary or secondary roles for high availability. Both the primary and secondary Monitoring personas collect log messages. In case the primary Monitoring persona goes down, the secondary Monitoring persona automatically assumes the role of the primary Monitoring persona.

Note At least one node in your distributed setup should assume the Monitoring persona. It is recommended that the Monitoring persona be on a separate, designated node for higher performance in terms of data collection and reporting.

– pxGrid—Cisco pxGrid is a method for network and security devices to share data with other devices through a secure publish and subscribe mechanism. These services are applicable for applications that are used external to ISE and that interface with pxGrid. The pxGrid services can share contextual information across the network to identify the policies and to share common policy objects. This extends the policy management.

Table 5 Recommended Number of Nodes and Personas in a Distributed Deployment
Minimum Number in a Deployment
Administration	1	2 (Configured as a high-availability pair)
Monitor	1	2 (Configured as a high-availability pair)
Policy Service	1	2—when the Administration/Monitoring/Policy Service personas are on the same primary/secondary appliances 5—when Administration and Monitoring personas are on same appliance 40—when each persona is on a dedicated appliance
pxGrid	0	2 (Configured as a high-availability pair)

You can change the persona of a node. See the “Set Up Cisco ISE in a Distributed Environment” chapter in the Cisco Identity Services Engine Admin Guide, Release 2.1 for information on how to configure personas on Cisco ISE nodes.

Requirements for CA to Interoperate with Cisco ISE

While using a CA server with Cisco ISE, make sure that the following requirements are met:

RSA key size should be 1024, 2048, or higher. In CA server, the key size is defined using certificate template. You can define the key size on Cisco ISE using the supplicant profile.
Key usage should allow signing and encryption in extension.
While using GetCACapabilities through the SCEP protocol, cryptography algorithm and request hash should be supported. It is recommended to use RSA + SHA1.
Online Certificate Status Protocol (OCSP) is supported. This is not directly used in BYOD, but a CA which can act as an OCSP server can be used for certificate revocation.

Note EJBCA 4.x is not supported by Cisco ISE for proxy SCEP. EJBCA is supported by Cisco ISE for standard EAP authentication like PEAP, EAP-TLS, and so on.

If you use an enterprise PKI to issue certificates for Apple iOS devices, ensure that you configure key usage in the SCEP template and enable the “Key Encipherment” option.

For example, If you use Microsoft CA, edit the Key Usage Extension in the certificate template. In the Encryption area, click the Allow key exchange only with key encryption (key encipherment) radio button and also check the Allow encryption of user data check box.

Cisco ISE supports the use of RSASSA-PSS algorithm for trusted certificates and endpoint certificates for EAP-TLS authentication. When you view the certificate, the signature algorithm is listed as 1.2.840.113549.1.1.10 instead of the algorithm name.

Note However, if you use the Cisco ISE internal CA for the BYOD flow, the Admin certificate should not be signed using the RSASSA-PSS algorithm (by an external CA). The Cisco ISE internal CA cannot verify an Admin certificate that is signed using this algorithm and the request would fail.

Cisco ISE Installation Files, Updates, and Client Resources

There are three resources you can use to download to provision and provide policy service in Cisco ISE:

Cisco ISE Downloads from the Download Software Center
Cisco ISE Live Updates
Cisco ISE Offline Updates

Cisco ISE Downloads from the Download Software Center

In addition to the.ISO installation package required to perform a fresh installation of Cisco ISE as described in Installing Cisco ISE Software, you can use the Download software web page to retrieve other Cisco ISE software elements, like Windows and Mac OS X agent installers and AV/AS compliance modules.

Downloaded agent files may be used for manual installation on a supported endpoint or used with third-party software distribution packages for mass deployment.

To access the Cisco Download Software center and download the necessary software:

Cisco ISE Live Updates

Cisco ISE Live Update locations allow you to automatically download Supplicant Provisioning Wizard, Cisco NAC Agent for Windows and Mac OS X, AV/AS support (Compliance Module), and agent installer packages that support client provisioning and posture policy services. These live update portals should be configured in Cisco ISE upon initial deployment to retrieve the latest client provisioning and posture software directly from Cisco.com to the Cisco ISE appliance.

Prerequisite:

If the default Update Feed URL is not reachable and your network requires a proxy server, you may need to configure the proxy settings in Administration > System > Settings > Proxy before you are able to access the Live Update locations. If proxy settings are enabled to allow access to the profiler and posture/client provisioning feeds, then it will break access to the MDM server as Cisco ISE cannot bypass proxy services for MDM communication. To resolve this, you can configure the proxy service to allow communication to the MDM servers. For more information on proxy settings, see the “Specify Proxy Settings in Cisco ISE” section in the “Administer Cisco ISE” chapter of the Cisco Identity Services Engine Admin Guide, Release 2.1.

Cisco ISE, Release 2.1.0.474 Patch Updates

This section provides information on patches that were made available after the initial availability of the Cisco ISE 2.1 release. Patches are cumulative such that any patch version also includes all fixes delivered in the preceding patch versions. Cisco ISE version 2.1.0.474 was the initial version of the Cisco ISE 2.1 release. After installation of the patch, you can see the version information from Settings > About Identity Services Engine page in the Cisco ISE GUI and from the CLI in the following format “2.1.0.474 patch N”; where N is the patch number.

Note Within the bug database, issues resolved in a patch have a version number with different nomenclature in the format, “2.1(0.9NN)” where NN is also the patch number, displayed as two digits. For example, version “2.1.0.474 patch 1' corresponds to the following version in the bug database “2.1(0.901)”.

TACACS Authorization Report

Perform the following steps to view the contents of the Command column in the TACACS Authorization report:

Step 1 Choose ISE Reports > Device Administration > TACACS Authorization.

Step 2 Choose Settings > Fix Columns > Command.

The Command column moves as the first column in the report. You can drag the boundary on the right side of the Command column heading until you reach the desired column width.

Note You can perform the above steps to view the last column in any report, which does not fit existing content.

Custom Attributes in TACACS+ Profiles

When adding custom attributes in TACACS+ profiles, it is recommended not to use asterisk (*) and equal to (=) symbols in the argument. TACACAS+ considers asterisk (*) and equal to (=) symbols as separators, which reformats the Name and Value fields and changes the Mandatory Type to Optional.

Gm 3400 Engine Review

New Features and Resolved Issues in Cisco ISE Version 2.1.0.474—Cumulative Patch 1

New Features and Resolved Issues:

Addition of CoA Reauthenticate in CoA Type of Hotspot Portal
Posture Patch Management Enhancements
Important Note After you Install Cisco ISE 2.1 Patch 1
Resolved Issues in Cisco ISE Version 2.1.0.474—Cumulative Patch 1

Addition of CoA Reauthenticate in CoA Type of Hotspot Portal

CoA Reauthenticate is added in CoA Type of Hotspot Portal and you can configure CoA Type in Hotspot portal by choosing CoA Terminate or CoA Reauthenticate options.

If you choose CoA Terminate, no VLAN is required for configuration of Hotspot Portal and VLAN DHCP Release Page Settings option is disabled. If you choose CoA Reauthenticate, you can configure VLAN.

Note We recommend that you configure hotspot using CoA Reauthenticate option (selected by default) to avoid experiencing delay in getting connected to the guest network. CoA Terminate starts a new network session, which causes the client to go through the DHCP process again. Some wireless clients may not reconnect automatically to the ISE guest network, which forces guests to manually connect to the network.

Posture Patch Management Enhancements

Support for severity levels is added to the Posture Patch Management Condition and Patch Management Remediation.

The following are the newly added severity levels:

Critical only
Important & critical
Moderate, Important & critical
All - low to critical

You can check if the patches with selected severity levels are up to date from Posture Patch Management Condition. The Check patches installed drop-down with the severity levels is enabled in Patch Management Condition only when the Check Type is chosen as Up to Date.

You can check and install missing patches with selected severity levels from Posture Patch Management Remediation. The Check patches installed drop-down with the severity levels in Patch Management Remediation is enabled only when the Remediation Option is chosen as Install missing patches.

This Severity Level enhancement is applicable only for clients that have AnyConnect 4.3 or later versions. If you have not configured the severity level in posture patch management condition in ISE and a client with AnyConnect 4.3 or later connects to the ISE server, AnyConnect defaults to Critical only support.

Note Windows compliance module 3.6.10611.2 is required for this update.

Important Note After you Install Cisco ISE 2.1 Patch 1

If you are not using the TrustSec features, we recommend you to disable the statistics collection. To stop the statistics collection in Cisco ISE GUI, navigate to Work Centers> TrustSec > Overview > Dashboard and click the Stop icon above the dashlets.

Note If you see the statistics already in stop status in TrustSec dashboard, we still recommend you to start and stop the statistics.

Resolved Issues in Cisco ISE Version 2.1.0.474—Cumulative Patch 1

Table 13 lists the issues that are resolved in Cisco Identity Services Engine, Release 2.1 cumulative
patch 1. To obtain the patch file necessary to apply the patch to Cisco ISE, Release 2.1, log in to the Cisco Download Software site at http://www.cisco.com/cisco/software/navigator.html?a=a&i=rpm (you might be required to provide your Cisco.com login credentials), navigate to Security > Access Control and Policy > Cisco Identity Services Engine > Cisco Identity Services Engine Software, and save a copy of the patch file to your local machine.
