Cisco Identity Services Engine (ISE) is a security policy management platform that provides secure access to network resources. Cisco ISE allows enterprises to gather real-time contextual information from networks, users, and devices. An administrator can then use this information to make proactive governance decisions by creating access control policies for the various network elements, including access switches, Cisco Wireless Controllers, Virtual Private Network (VPN) gateways, and data center switches. Cisco ISE acts as the policy manager in the Cisco TrustSec solution and supports TrustSec software-defined segmentation.

Cisco ISE is available on Secure Network Server appliances with different performance characterizations, and also as software that can be run on a virtual machine (VM). Note that you can add more appliances to a deployment for better performance.

Cisco ISE has a scalable architecture that supports standalone and distributed deployments, but with centralized configuration and management. It also enables the configuration and management of distinct personas and services, thereby giving you the ability to create and apply services where needed, in a network, but operate the Cisco ISE deployment as a complete and coordinated system.

For more information about the features that are supported in this Cisco ISE release, see the Cisco Identity Services Engine Administrator Guide.

System Requirements

For an uninterrupted Cisco ISE configuration, ensure that the following system requirements are fulfilled.

  • Legacy Access Control Server (ACS) and Network Access Control (NAC) appliances (including the Cisco ISE 3300 Series) are not supported in Cisco ISE, Release 2.0, and later.

Federal Information Processing Standard Mode Support

Cisco ISE uses embedded Federal Information Processing Standard (FIPS) 140-2-validated cryptographic module, Cisco FIPS Object Module Version 6.2 (Certificate #2984). For details about the FIPS compliance claims, see Global Government Certifications.

When FIPS mode is enabled on Cisco ISE, consider the following:

  • All non-FIPS-compliant cipher suites will be disabled.

  • Certificates and private keys must use only FIPS-compliant hash and encryption algorithms.

  • RSA Private keys must be of 2048 bits or greater.

  • Elliptical Curve Digital Signature Algorithm (ECDSA) Private keys must be of 224 bits or greater.

  • Diffie–Hellman Ephemeral (DHE) ciphers work with Diffie–Hellman (DH) parameters of 2048 bits or greater.

  • SHA1 is not allowed to generate ISE local server certificates.

  • The anonymous PAC provisioning option in EAP-FAST is disabled.

  • The Local SSH server operates in FIPS mode.

  • The following protocols are not supported in FIPS mode for RADIUS:

    • EAP-MD5

    3. Under Downloads, check the Ask Where to Save Each File before Downloading check box.

Support for Microsoft Active Directory

Cisco ISE works with Microsoft Active Directory servers 2003, 2003 R2, 2008, 2008 R2, 2012, 2012 R2, 2016, and 2019 at all functional levels.


  • It is recommended that you upgrade Windows server to a supported version as Microsoft no longer supports Window server 2003 and 2003 R2. .

  • Microsoft Active Directory Version 2000 or its functional level is not supported by Cisco ISE.

Cisco ISE supports multidomain forest integration with Active Directory infrastructure to support authentication and attribute collection across large enterprise networks. Cisco ISE supports up to 50 domain join points.

Improved User Identification

Cisco ISE can identify Active Directory users when a username is not unique. Duplicate usernames are common when using short usernames in a multidomain Active Directory environment. You can identify users by Software Asset Management (SAM), Customer Name (CN), or both. Cisco ISE uses the attributes that you provide to uniquely identify a user.

Update the value of the following:

  • SAM: Update this value to use only the SAM in the query (the default).

  • CN: Update this value to use only CN in the query.

  • CNSAM: Update this value to use CN and SAM in the query.

To configure the attributes mentioned above for identifying Active Directory users, update the IdentityLookupField parameter in the registry on the server that is running Active Directory:


Supported Ciphers

In a clean or fresh install of Cisco ISE, SHA1 ciphers are disabled by default. However, in case of an upgrade from an existing version of Cisco ISE, the SHA1 ciphers are preset to the options from the earlier version. You can view and change the SHA1 ciphers settings using the Allow SHA1 Ciphers field (Administration > System > Settings > Security Settings).

What is New in Cisco ISE, Release 2.7?

Auto-Logon of Self-Registered Guest after Sponsor Approval

You can now enable automatic logon for a self-registered guest after sponsor approval.

Business Outcome: The guest user is automatically logged in when the sponsor approves the guest access request. This simplifies the process and improves customer experience.

Cisco Support Diagnostics Connector

The Cisco Support Diagnostics Connector helps Cisco Technical Assistance Center (TAC) and Cisco support engineers to obtain deployment information from the primary administration node.

Business Outcome: TAC can now get support information of any particular node in a deployment through the connector. This data enables quicker and better troubleshooting.

CLI Show Logging Enhancement

When you run the show logging command in the Command Line Interface (CLI), the content is displayed in the Unix less environment. You can see the supported less commands by typing “H”.

Business Outcome: Less is more useful for viewing the content of large files. This saves time when examining log files.

EAP TEAP Support

Cisco ISE 2.7 supports the Tunnel Extensible Authentication Protocol (TEAP). The type-length-value (TLV) objects are used within the tunnel to transport authentication-related data between the EAP peer and the EAP server. You can use EAP-MS-CHAPv2 or EAP-TLS as the inner method. EAP chaining is supported for TEAP. EAP chaining allows Cisco ISE to run both the inner methods for user and machine authentication inside the same TEAP tunnel. This enables Cisco ISE to correlate the authentication results and apply the appropriate authorization policy, using the EAPChainingResult attribute.

Business Outcome: TEAP is a tunnel-based EAP method that enables secure communication between a peer and a server by using the Transport Layer Security (TLS) protocol to establish a tunnel and encrypt further communications.

Endpoint Ownership Enhancement

The Endpoint Ownership information is now stored across all the Policy Service nodes (PSNs) with the help of the Light Session Directory (LSD).

Business Outcome: This avoids endpoint ownership flapping.

Feed Service Update

If you have customized your profiler conditions and do not want the profiler feed to replace those conditions, you can manually download OUI updates without downloading the policy updates.

Business Outcome: Improved profiler accuracy with less overhead.

Grace Access

You can grant 5 to 30 minutes of internet access to self-registered guests who are waiting for sponsor approval to your corporate network.

Business Outcome: The guest users can access the internet while waiting for approval.

Guest Password Recovery

You can now enable the Reset Password option in the Guest portal for self-registered guests. Self-registered guests with valid guest account can use this option when they forget their password. When you click this option, the self-registration page is launched. You can enter your phone number or email address (whichever you are registered with) and enter a new password.

Business Outcome: Improves the customer experience and reduces calls to Customer Support team.

Interactive Help

The Interactive Help provides tips and step-by-step guidance to complete tasks with ease.

Business Outcome: This helps the end users to easily understand the work flow and complete their tasks with ease.

Phone Number as the Guest User Identifier

In addition to email address or username, guest users can now use their phone numbers as their user ID for guest access.

Business Outcome: Guest users can now use their mobile numbers as their user ID. This makes it easier for them to remember their user ID.

Profiler Forwarder Persistence Queue

The Profiler Forwarder Persistence Queue stores incoming events before they are sent to the profiler module for further processing.

Business Outcome: This reduces the loss of events due to a sudden burst of events. This queue uses the ISE Messaging Service, and is enabled by default. It requires port 8671 to be open between all Cisco ISE nodes.

Role Based Access Policy

In the Cisco ISE admin portal, the Policy menu option under Administration > Admin Access > Authorization has been renamed to RBAC Policy. The RBAC Policy window is used to add and configure policies for administrator groups.

Secure SMTP

Guest email notifications can now be sent through a secure SMTP server.

Business Outcome: Improved security for Guest emails in your network.

Secure Unlock Client

The Secure Unlock Client mechanism is used to provide root shell access on Cisco ISE CLI for a certain period of time.

Business Outcome: The Secure Unlock client feature has been implemented using the Consent Token tool, which securely grants privileged access for Cisco products in a trusted manner.

TrustSec Enhancements

The HTTPS REST API replaces the existing RADUIS protocol to provide all the required TrustSec information to the network devices.

Business Outcome: It enhances the efficiency and ability to download large configurations in a short period of time as compared to the existing RADIUS protocol.

Known Limitations and Workarounds

Radius EAP Authentication Performance when Using Default Self-Signed Certificate

In Cisco ISE 2.7, the default self-signed certificate key size is increased to 4096 for enhanced security. Radius EAP authentication performance might be affected, if the default self-signed certificate is used for EAP authentication.

Few TLS Ciphers Cannot be Disabled

The following ciphers cannot be disabled in Cisco ISE:



The Cisco ISE scenarios that could use these ciphers include:
  • Cisco ISE as an EAP or ERS server

  • Cisco ISE downloads Certificate Revocation List from an HTTPS or a secure LDAP server

  • Cisco ISE as a secure TCP syslog or LDAP client

The Cisco ISE components that could use these ciphers include: Admin UI, all portals, MDM client, pxGrid, and PassiveID Agent.

Security Group Access Control List

When you try to create a Security Group ACL (SGACL), sometimes the following error message is displayed:

Failed to create policy, CFS provision failed.

This is because creating and updating egress matrix cell flows are not supported for multiple matrixes in Cisco ISE. The following External RESTful Services (ERS) requests are also not supported in the Multiple Matrix mode:




You should, therefore, uncheck the Allow Multiple SGACL check box in the TrustSec Matrix Settings (Work > TrustSec > Settings > TrustSec Matrix Settings) window. This enables you to create an SGACL, and no error message is displayed.

Upgrade Information


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

Upgrading to Release 2.7

You can directly upgrade to Release 2.7 from the following Cisco ISE releases:

  • 2.2

  • 2.3

  • 2.4

  • 2.6

If you are on a version earlier than Cisco ISE, Release 2.2, you must first upgrade to one of the releases listed above and then upgrade to Release 2.7.


We recommend that you upgrade to the latest patch in the existing version before starting the upgrade.

License Changes

Device Administration Licenses

There are two types of device administration licenses: cluster and node. A cluster license allows you to use device administration on all policy service nodes in a Cisco ISE cluster. A node license allows you to use device administration on a single policy service node. In a high-availability standalone deployment, a node license permits you to use device administration on a single node in the high availability pair.

The device administration license key is registered against the primary and secondary policy administration nodes. All policy service nodes in the cluster consume device administration licenses, as required, until the license count is reached.

Cluster licenses were introduced with the release of device administration in Cisco ISE 2.0, and is enforced in Cisco ISE 2.0 and later releases. Node licenses were released later, and are only partially enforced in releases 2.0 to 2.3. Starting with Cisco ISE 2.4, node licenses are completely enforced on a per-node basis.

Cluster licenses have been discontinued, and now only node Licenses are available for sale.

However, if you are upgrading to this release with a valid cluster license, you can continue to use your existing license upon upgrade.

The evaluation license allows device administration on one policy service node.

Licenses for Virtual Machine nodes

Cisco ISE is also sold as a virtual machine (VM). For this Release, we recommend that you install appropriate VM licenses for the VM nodes in your deployment. Install the VM licenses based on the number of VM nodes and each VM node's resources, such as CPU and memory. Otherwise, you will receive warnings and notifications to procure and install the VM license keys. However, the installation process will not be interrupted. From Cisco ISE, Release 2.4, you can manage your VM licenses from the GUI.

VM licenses are offered under three categories—Small, Medium, and Large. For instance, if you are using a 3595-equivalent VM node with eight cores and 64-GB RAM, you might need a Medium category VM license if you want to replicate the same capabilities on the VM. You can install multiple VM licenses based on the number of VMs and their resources as per your deployment requirements.

VM licenses are infrastructure licenses. Therefore, you can install VM licenses irrespective of the endpoint licenses available in your deployment. You can install a VM license even if you have not installed any Evaluation, Base, Plus, or Apex license in your deployment. However, in order to use the features that are enabled by the Base, Plus, or Apex licenses, you must install the appropriate licenses.

VM licenses are perpetual licenses. VM licensing changes are displayed every time you log in to the Cisco ISE GUI, until you check the Do not show this message again check box in the notification pop-up window.

If you have not purchased an ISE VM license earlier, see the Cisco Identity Services Engine Ordering Guide to choose the appropriate VM license to be purchased.


If you have purchased ISE VM licenses without a PAK, you can request VM PAKs by emailing Include the Sales Order numbers that reflect the ISE VM purchase, and your Cisco ID in your email. You will be provided a medium VM license key for each ISE VM purchase you have made.

For details about VM compatibility with your Cisco ISE version, see "Hardware and Virtual Appliance Requirements" chapter in the Cisco Identity Services Engine Installation Guide for the applicable release.

For more information about the licenses, see the "Cisco ISE Licenses" chapter in the Cisco Identity Services Engine Administrator Guide.

Upgrade Procedure Prerequisites

  • Run the Upgrade Readiness Tool (URT) before an ISE software upgrade in order to check if the configured data can be upgraded to the required ISE version. Most upgrade failures occur because of data upgrade issues; the URT is designed to validate the data before the actual upgrade and reports and tries to fix the issues, wherever possible. The URT can be downloaded from the Cisco ISE Download Software Center.

  • We recommend that you install all the relevant patches before beginning the upgrade.

For more information, see the Cisco Identity Services Engine Upgrade Guide.


Telemetry provides valuable information about the status and capabilities of the Cisco Identity Services Engine (ISE) appliance. Telemetry is used by Cisco to improve appliance lifecycle management for IT teams who have deployed Cisco ISE. Collecting this data helps the product teams serve customers better. This data and related insights enable Cisco to proactively identify potential issues, improve services and support, facilitate discussions to gather additional value from new and existing features, and assist IT teams with inventory report of license entitlement and upcoming renewals.

Types of data collected include: Product Usage Telemetry and Cisco Support Diagnostics.

Product Usage Telemetry

Cisco Identity Services Engine (ISE) collects telemetry data. This data is used by Cisco to improve appliance lifecycle management for IT teams who have deployed Cisco ISE. By default, product usage telemetry is enabled. See the Cisco Identity Services Engine Administrator Guide for instructions on how to disable this feature. It may take up to 24 hours after the feature is disabled for Cisco ISE to stop sharing telemetry data.

Cisco Support Diagnostics

The Cisco Support Diagnostics Connector is a new feature that helps Cisco Technical Assistance Center (TAC) and Cisco support engineers to obtain support information on the deployment through the primary administration node. By default, this feature is disabled. See the Cisco Identity Services Engine Administrator Guide for instructions on how to enable this feature.

Cisco ISE Live Update Portals

Cisco ISE Live Update portals help you to automatically download the Supplicant Provisioning wizard, AV/AS support (Compliance Module), and agent installer packages that support client provisioning and posture policy services. These live update portals are configured in Cisco ISE during the initial deployment to retrieve the latest client provisioning and posture software directly from to the corresponding device using Cisco ISE.

If the default Update portal URL is not reachable and your network requires a proxy server, configure the proxy settings by choosing Administration > System > Settings > Proxy before you access the Live Update portals. If proxy settings allow access to the profiler, posture, and client-provisioning feeds, access to a Mobile Device Management (MDM) server is blocked because Cisco ISE cannot bypass the proxy services for MDM communication. To resolve this, you can configure the proxy services to allow communication to the MDM servers. For more information on proxy settings, see the "Specify Proxy Settings in Cisco ISE" section in the Cisco Identity Services Engine Administrator Guide.

Client Provisioning and Posture Live Update Portals
