ISE 2.7 TACACS Issue?

NashLena

Strange Device Admin issue in a new 2 node deployment.

Only 1 of the nodes will service TACACS requests.

Tested on both IOS and NX-OS and if they try to send TACACS requests to the 'secondary' node they fail and are not recorded in any ISE logs.

If I remove the Device Admin role from the secondary node and re-add it, TACACS starts working on this node but stops responding on the primary node.

If I then remove Device Admin from primary node and re-add, it starts working again on primary node but stops working on secondary.

 

2 x 3615 Appliances running ISE 2.7 Patch 2

Both nodes are configured with Admin, Monitoring, Policy Service (including Device Admin) and PXGrid

Using Smart Licensing, has 2 Device Admin licenses in portal (and shown correctly as 'in use')

 

I'd be grateful if anyone has seen this or something similar before and has any advice. I would go straight to TAC but there is an issue with the purchased support package being correctly registered and I'm waitying for it to get sorted by the customer / supplying partner

 

Thanks

Hi @NashLena 

Seems like a bug: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvw47006

I think you have to sort out your issue with the contract and engage TAC for further troubleshooting.

Well this is interesting because we do have many TACACS errors related to Nexus devices being not able to reach ISE/TACACS and not impacting Catalyst devices ... will have a look at that bug conditions !
