Evaluation Licenses


All Licensing options and capabilities including the Evaluation license are explained in the ISE Ordering Guide.


Upon installation, every ISE node has 90-day free evaluation licenses for up to 100 endpoints for all ISE services.

If you need more than 90 days for your evaluation, provide your ISE Primary PAN node's Unique Device Identifier (UDI) to your Cisco Sales Representative and they can generate any ISE licenses for an additional 90-days or even 365 days using our Cisco Internal License Generation Tool.


Please include the ISE PAN primary and secondary UDI details in your extended evaluation license requests!

Licenses cannot be generated for your ISE nodes without the UDIs for your ISE PAN(s).

Failure to include them will simply result in delays in getting your licenses.


If you have already purchased ISE and want to try Device Administration (TACACS+) on your existing deployment, your Cisco Sales Representative may generate an ISE_TACACS-90DAY or ISE_TACACS-365DAY license using your ISE PAN UDI with our Cisco Internal License Generation Tool.


If you need to extend your evaluation licenses for >365 days or >100 endpoints then please contact the ISE Product Management team.



How to Obtain the Unique Device Identifier (UDI)


Licenses are generated for your ISE installation's Unique Device Identifier (UDI) from your ISE Primary Policy Administration Node (PAN) and optionally the Secondary PAN in the case of a Failover. The UDI consists of :

  • Product Identifier (PID)
  • Version Identifier (VID)
  • Serial Number (SN)


The easiest way to obtain the ISE UDI for the PAN primary and secondary is at the bottom of the ISE page Administration > System > Licensing:


Alternatively, you may use the About menu in the web interface of your ISE Policy Administration Node(s):




And you may use the show udi CLI command from console of your ISE Administration node(s)  :

ise-1/admin# show udi
VPID:   V01
Serial: 9JQKGRH6K00
