Cisco - TACACS+ problem

Default TACACS+ problem


It seems like i locked myself out from our 4006 switch.
I activated TACACS+ authentication on the switch towards a Cisco ACS server.
Unfortunately I forgot to configure the TACACS+ secret key on the switch and
now it won't let me in. Neither TELNET nor serial console access works. It
doesn't even give me a loginprompt.
I'm afraid I will have to do the password recovery procedure.

Before moving on with the password recovery procedure I just wanted to check
with you guys here if there is some other way to get into the switch again.

Thanks and regards,

Rutger
Sweden

It might take awhile to get a prompt. When you will get the prompt use telnet
password for user name and than again for password.

With best regards,
Andrey.

Hello!

When I telnet into the switch it immediatly gives me a "authentication
failed" and then exits.
