Ok so I was trying to configure TACACs and locked myself out of the cisco switch running IOS 12.1. When I telnet to the device it is asking for a username and password, but since the TACACS isn't working and there is no username in the local database, I can't log in. So, I think I need to somehow execute a "no aaa new-model" on the device.
I know the SNMP RW community string. Is there a program I can get to execute this config change via SNMP write?
