AAA-3-BADSERVERTYPEERROR

zebranutz80 · ‎11-01-2007

I was just sent a replacement 3660. I was entering in some of the config prior to replacement to reduce downtime. After reloading the router I receive this error:00:04:48: %AAA-3-BADSERVERTYPEERROR: Cannot process authentication server type t

acacs+ (UNKNOWN)

% Authentication failed.

The router then goes to:

Cisco3660-2 con0 is now available

Press RETURN to get started.

After I press RETURN, nothing happens. I do not get a Username or Password promp. After pressing ENTER the router waits 15 seconds then tells me Authentication Failed even though I didn't type anything.

I would simply like to erase the existing configuration but the only tool at my disposal is ROMMON. Does anyone know how to erase a config from ROMMON?

I opened a TAC case on how to erase NVRAM and the faulty configuration. See below:

If you want to erase the configuration, send the router into Rommon and

type:

confreg 0x2142

reset

Then the router will reload and skip your configuration so if you wish you can type erase nvram or erase start and the configuration will be erased.

Then you have to change the configuration register back to 0x2102, these are the commands:

config t

config-register 0x2102

end
