Catalyst 9800 - Interim update recommended setting

[Luna99923]

Hello,

I am looking for the recommended configuration for interim update interval on a Catalyst 9800 Wireless LAN Controller. We are currently running version 17.12.5 on our 9800s and use ISE 3.4.  This is how we currently have the 9800s and Policy Profiles setup:

Thanks

                                Behavior: Only send radius accounting  update on IP address change

Hi Mark,

Sorry to bring up an older post, but where exactly do you configure the accounting interim interval on the 9800?

We’re seeing a high volume of alerts from ISE, and I suspect it’s due to guest WiFi generating too many interim updates. I’ve had a look through the config but haven’t been able to find where the interval is actually set.

Thanks

Neil
