CoA action reauth impact

Hi All,

Can somebody tell me the impact of the CoA action reauth impact

Below is my scenario,

I have wired/Wireless/VPN users who are postured from ISE ( primary & secondary ISE nodes are there in my setup) . As of now the CoA action is none. If I change the CoA action to reauth, how will this impact the users

Does the users feel taking more time for authentication,

Does it create more load the network devices

Does it create more load on the ISE

Regards

Nikhil

The CoA action is an endpoint profiling option to re-auth based on changes on profiler policies and authorization rules.

No, this does not impact the regular authentications.

Yes, potentially as it triggers additional authentications.

Yes, potentially as ISE needs initiate these CoA requests and handle subsequent authentications.
