Hi,

what is the error message reported on ACS?

Are you sure that you are using the same key on ACS and cat4k?

Can you configure "ip tacacs source-interface " with the vlan interface you are using as source?

You can also collect these debugs:

- deb aaa authentication

- deb tacacs

Cheers

Marco
