Question about TACACS source interface.

Hello.

I'm reading more posts about the "ip tacacs source-interface".

I'm using a Catalyst 4503 with IOS version 12.2(44)SG1 configured to use vlan101's IP address as source address for the T+ request.

However, the switch continues to use another IP and authetication fails.

The source-interface command is set globally and for the AAA group.

Any ideas?

Thanks.

Regards.

Andrea
