Identity of a NAS on Cisco Secure ACS

[j.warrier]

Is there any way I can define the IP address used by a NAS when it tries to authenticate the users, on a Cisco Secure ACS? For example, for a gateway router with 4 interfaces configured to authenticate against a AAA server, how do I configure the IP address used by the router when it initiates a connection to the AAA server?

Hi,

Yes its possible. In the global config mode, you need to execute one of the following commands depending on which protocols you use:

If you are using tacacs+:

ip tacacs source-interface subinterface-name/interface-name

If you are using radius:

ip radius source-interface subinterface-name/interface-name

I hope this helps. Thanks,
