Cisco ISE Licenses

This chapter describes the licensing mechanism and schemes that are available for Cisco ISE and how to add and upgrade licenses.

Cisco ISE Licenses

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.

To maximize economy for customers, licensing in Cisco ISE is supplied in different packages as Base, Plus, Apex, and Mobility Upgrade.

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 licences to enable that functionality.

Licenses are uploaded to the Primary PAN and propagated to the other Cisco ISE nodes in the cluster. Licenses are centrally managed by the PAN. If you have two PANs deployed in a high-availability pair, obtain a license based on the hardware IDs (UIDs) of both the Primary and Secondary PANs. After you obtain the license, add it only to the Primary PAN. The license gets replicated to the Secondary PAN.

After you install the Cisco ISE software and initially configure the appliance as the Primary PAN, you must obtain a license for Cisco ISE and then register that license. You register all licenses to the Cisco ISE Primary PAN via the Primary and Secondary PAN hardware UID. The Primary PAN then centrally manages all the licenses that are registered for your deployment.

Cisco recommends installing both Base and Plus or Apex licenses at the same time.

Using a Plus or Apex license requires also using a Base license. However, you do not need a Plus license in order to have an Apex license or vice versa, since there is no overlap in their functionality.
When you install a Base or Mobility Upgrade license, Cisco ISE continues to use the default Evaluation license as a separate license for the remainder of its duration.
You cannot upgrade the Evaluation license to an Plus and/or Apex license without first installing the Base license.
Cisco ISE allows you to use more Plus and/or Apex licenses on the system than Base licenses. For example, you can have 100 Base licenses and Plus licenses.
When you install a Mobility Upgrade license, Cisco ISE enables all Wired, Wireless, and VPN services.

License Consumption

You purchase licenses for the number of concurrent users on the system . A Cisco ISE user consumes a license during an active session (always a Base; and a Plus and an Apex license, if you use the functionality covered by these licenses). Once the session ends, the license is released for reuse by other users.

Restriction

Cisco ISE license architecture consumption logic relies on authorization policy constructs. Cisco ISE uses the dictionaries and attributes within authorization rules to determine the license to use.

The Cisco ISE license is counted as follows:

A Base license is consumed for every active session. The same endpoint also consumes Plus and Apex licenses depending on the features that it is using.

Note

TACACS+ sessions do not consume a base license, but RADIUS sessions consume a base license.

The endpoint consumes the Base license before it consumes a Plus and Apex license.
The endpoint consumes the Plus license before it consumes an Apex license.
One Plus license is consumed per endpoint for any assortment of the license's features. Likewise, one Apex license is consumed per endpoint for any assortment of its features.
Licenses are counted against concurrent, active sessions.
Licenses are released for all features when the endpoint's session ends.
pxGrid is used to share context collected by ISE with other products. A Plus license is required to enable pxGrid functionality. There is no session count decrement when context for session is shared. However, to use pxGrid, the number of Plus sessions licensed must be equal to the number of Base sessions licensed. For more information, see Cisco ISE Licenses and Services section in Cisco Identity Services Engine Ordering Guide.
One AnyConnect Apex user license is consumed by each user who uses AnyConnect regardless of the number of devices that the user owns and whether or not the user has an active connection to the network.
You can enable the TACACS+ service by adding a Device Administration license on top of an existing Base or Mobility license. This feature does not consume licenses.

To avoid service disruption, Cisco ISE continues to provide services to endpoints that exceed license entitlement. Cisco ISE instead relies on RADIUS accounting functions to track concurrent endpoints on the network and generates an alarm when the endpoint count of the previous day exceeded the amount of licenses.

View License Consumption

You can view your system's current license consumption from the Licensing dashboard at: Administration > System > Licensing. Consumption is portrayed as in the following image:

Figure 1. Traditional License Consumption

The License Consumption graph, in the License Usage area, is updated every 30 minutes. This window also displays the type of licenses purchased, the total number of concurrent users permitted on the system, and the expiry date of subscription services.

If you want to see your system's license consumption over multiple weeks, click Usage Over Time. Each bar in the graph shows the maximum number of licenses used during a period of one week.

Unregistered License Consumption

Problem

License consumption relies on the attributes used in the authorization policy with which the endpoint is matched.

Consider you only have a Base license registered on your system (you deleted the 90-day Evaluation license). You will be able to see and configure the corresponding Base menu items and features.

If you configure (mis-configure) an authorization policy to use a feature (for example: Session:PostureStatus) that requires an Apex license, and if an endpoint matches this authorization policy then:

The endpoint will consume an Apex license, despite the fact that an Apex license has not been registered on the system.
Notifications to this effect will appear whenever you log in.
Cisco ISE displays notifications and alarms "Exceeded license usage than allowed" (technically, this is to be expected as there are no registered Apex licenses on the system, but an endpoint is consuming one).

Possible Causes

Due to authorization policy mis-configuration, the Licensing table can show that Cisco ISE is consuming a license you have not purchased and registered. Before you purchase Plus or an Apex license, the Cisco ISE GUI does not display the functionality covered by that license. However, once you have purchased a license, the user interface continues to display their functionality even after the license has expired or exceeded its endpoint consumption. Thus, you are able to configure them even if you do not have a valid license for them.

Solution

In the Cisco ISE GUI, click the Menu icon () and choose Policy > Authorization, identify the authorization rule that is using the feature(s) for which you do not have a registered license, and reconfigure that rule.

Manage License Files

This section explains how to register, re-host, renew, migrate, upgrade, and remove ISE licenses:

Remove Licenses

Register Licenses

Before you begin

Consult your Cisco partner/account team about the types of licenses and number of concurrent users you require for your installation, together with the various packages you can purchase to maximize economy.

Procedure

Step 1	From the ordering system (Cisco Commerce Workspace - CCW) on Cisco's website www.cisco.com, order the required licenses. After about an hour, an email confirmation containing the Product Authorization Key (PAK) is sent.
Step 2	From the Cisco ISE Administration portal, choose AdministrationSystemLicensing. Make a note of the node information in the Licensing Details section: Product Identifier (PID), Version Identifier (VID), and Serial Number (SN).
Step 3	Go to www.cisco.com/go/licensing, and where prompted, enter the PAK of the license you received, the node information, and some details about your company. The PAK number can be obtained from the sticker located on the software's CD sleeve or on a License Claim Certificate that was physically mailed to you. Post license registration, the permanent license will be sent to your provided email address. Licenses are sent from licensing@cisco.com, add this address to your safe senders list to receive emails from this mailer.
Step 4	Save this license file to a known location on your system.
Step 5	From the Cisco ISE Administration portal, choose Administration > System > Licensing. In the License Files section, click the Import License button.
Step 6	Click Choose File and select the license file you previously stored on your system.
Step 7	Click Import.

The new license is now installed on your system.

What to do next

Choose the licensing dashboard, Administration > System > Licensing, and verify that the newly-entered license appears with the correct details.

Re-Host Licenses

Re-hosting means moving a license from one Cisco ISE node to another. From the licensing portal, you select the PAK of the license you want to move and follow the instructions for re-hosting. After one day, you are sent an email with a new PAK. You then register this new PAK for the new node, and remove the old license from the original Cisco ISE node.

Renew Licenses

Subscription licenses, such as Plus and Apex licenses, are issued for 1, 3 or 5 years. Cisco ISE sends an alarm when licenses are near their expiration date and again when the licenses expire.

Licenses must be renewed after they expire. This process is carried out by your Cisco partner or account team only.

Migrate and Upgrade Licenses

Cisco licensing policy supports migration from previous Cisco ISE versions, upgrading from wireless and VPN only to include wired deployments, and adding concurrent users and functionality. You can also purchase bundles of licenses to minimize your ongoing expenses. These scenarios are all covered in the licensing site, or for more information contact your Cisco partner/account team.

Note

If you have migrated from Cisco ISE version 1.2, your Advanced license covers all the features in both Plus and Apex licenses.

Note

After upgrading from Cisco ISE version 1.3 or 1.4, the system will show the default Evaluation license only if it existed on the system prior to upgrade.

Note

Mobility/Mobility Upgrade license is always displayed as Base/Plus/Apex in the user interface with its corresponding number of end points.

If your Cisco ISE node needs to support:

A larger number of concurrent users than the number for which you have licenses
Wired (LAN) access, and your system has only the Mobility license

You will need to upgrade your license(s) for that node. This process is carried out by your Cisco partner or account team only.

Remove Licenses

Before you begin

Keep the following in mind before attempting to remove a license:

If you have installed a Mobility Upgrade license after a Mobility license, you must remove the Mobility Upgrade license before you can remove the underlying Mobility license.
If you install a combined license, all related installations in the Base, Plus, and Apex packages are also removed.

Procedure

Step 1	Choose Administration > System > Licensing
Step 2	In the License Files section, click the check next to the relevant file name, and click Delete License.
Step 3	Click OK.
