Can the management centre send a Radius "AVP" to the Radius server?

Hi;

Can the management centre send a Radius attribute "AVP" to the Radius server? I mean in the Radius Authentication Request?  ideally, I would like the Management Centre to send the IP address of the user device supplying the username and password on the Management Centres login page, which in turn will be sent to the Radius server.

So ideally, the MC should send the following to the Radius server:  "username+password+the IP address of the device of the user trying to authenticate".

Kindly
