ISE CoA not send

phaaring

Hi All,

 

We have a Cisco ISE cluster with 4 nodes and using CoA for Wireless. Thats working fine.

 

The goal is to use CoA for switchports too and configured both ISE and the switch for CoA (default port). After initiating a CoA from ISE to a specific client (switchport) we found that the CoA is never recieved by the switch.

After creating and anlysing a TCP dump on the (right) PSN we found that ISE is never sending the CoA.

 

Below a screendump from the TCP dump with a full authentication.

Direct after this authentication the CoA is send but its not found in the trace. 

 

Any ideas?
