2600 Terminal Servers with Catalyst 4000/5000/5500/6500 Switches

I am trying to configure several Cisco 2600's with Async interfaces as terminal servers on our network for OOB managment, the problem that I am running into is with the Catalyst switches, if the catalyst switch is not not running TACACS+ for authentication I can do a reverse telnet out of the async port and connect successfully with the console password. If I have TACACS+ setup on the switch and try to connect via the exact same session it give me the prompt for the username and passcode (RSA Keyfob), but then it hangs after you enter the passcode and will eventually timeout and drop the session. I do not have this problem with routers running native IOS, only switches running the CatOS. If anyone has experienced this problem and has a solution I would greatly appreciate any help.

For the CAT OS, if the switch can't reach the TACACS server, it will not use the username as part of the authentication process. You would use the local password (telnet).

Here's a helpful link on understanding authentication:
