WLC AAA Source Interface / IP Address

[Evlaa2021]

Please can someone tell me what the source interface / address of AAA requests comes from in an AAA server over-ride configuration? If a client is connected to SSID ABC and that WLAN has AAA server over-ride addresses will the request be sources from the client or from the WLC interface group, is this sourced from a specific inteface for every WLAN? is there any way to specify where these requests are sourced from?

Also if a WLAN is anchored to another controller, will the AAA requests be sourced from the Anchor controller in this scenario?

These are all in various documentation. If you look at radius, you setup a NAD, your device and it’s sourced ip. Also in the guest anchor documentation it also describes where authentication is performed.

What are you trying to do? Or are you just trying to understand things better? Here are some docs to review:
