I got a 2610 router and trying to do a password recovery.  I recycle the router and do a CTRL-Break on it, then I do a confreg 0x2142
Next, I do ENABLE
Then, I do copy star run
From there, I'm at the Privleged Mode and should be able to do configure terminal, so I can clear out the enable password.  This is what happens.


CATHKMR01R1#conf t
Command authorization failed.

CATHKMR01R1#

Why is this?  Is there anyway besides clearing out the startup config to recovery the password?  I don't want to clear out my current config that's in there now.

Looks like the startup config that you're copying to running config contains Tacacs configuration commands. Without the username/password setup on the Tacacs server, you won't be able to do much.

Either get a username/password, or don't load the startup-config.

You're absolutely correct, it does have a TACACS server on it.  I'll just have to clear out the startup config then.  Thanks donjohnston!!

It just occured to me that there is a way to recover the configuration...

Once you've used the password recovery process to get into priviliged mode, get an ethernet interface configured. Setup a TFTP server off the ethernet interface and issue a "copy startup tftp". Once the file is on the TFTP server, open it and remove the TACACS commands, save it and then copy it back to NVRAM (copy tftp start).
