How to cluster ISE

Hi Team,

I have 6 boxes of ISE and we planned to make 2 as a PSN's.

how about other 4 ISE ...? How should i cluster them as admin and monitor nodes..?

It would depend on your

It would depend on your deployment but you can:

1. Configure 4 nodes to be PSNs

2. Place the nodes in a "node group" behind a load balancer. If you don't have a load balancer, you can configure the NADs in a way that the load is somewhat distributed. For instance, make PSN 1 be the primary Radius server and PSN 2 be the secondary for Wireless LAN Controllers. Then PSN 2 be the primary for switches while PSN 1 secondary. Then PSN 3 to be primary for ASAs/VPN, PSN 4 be the secondary, etc. 

3. You can then take the other two nodes and dedicate them for Administration and Monitoring. You can split the load by making one node be the primary for "Admin" but secondary for "Monitor" while making the second node be the primary for "Monitor" and secondary for "Admin"

Hope this helps!

License i should install in all Nodes or only Admin node ..?

Cisco Employee

No problem!

No problem! You only need one license and it is installed on the primary Admin node. However, make sure you include the S/N from the secondary node when registering your PAK file / requesting your license. That way you will be all set wheb /if you need to faulover to the secondaryvAdmin node. Thank you for rating helpful posts!
