Cisco ACS 4.2- Nortel Switch - TACACS+ issue

[Prasan Venky]

Hi Experts,

When i tried authenticating my Nortel switch with Cisco ACS 4.2 using TACACS+, its not working. I get Authentication failed message from nortel switch, but in ACS it shows Auth OK message.

Even i see only "Radius (Nortel)" while creating group. But not TACACS+ (Nortel).

Whether any special configuration needs to be done on ACS..? Anyone got it worked already...?

We need Tacacs+ for accounting of nortel devices.

Quick response is highly appreciated.

Are you sure Nortel supports Tacacs? I was going through Nortel 51XX/52xx series switch guide and I don't see tacacs support listed anywhere. It only talks about radius. I've attached the file for your reference.

Here are the VSA you may define on ACS.
VSA Data for VSA ID 2 (UPC)
User VSA ID 2 (UPC value)
OM5000_ADMIN 16
OM5000_OPERATOR 256
OM5000_OBSERVER 4096
OM5000_CUSTOMER1 8192
OM5000_CUSTOMER2 12288
