I have a pre-shared key that was set up in our PIX 6.3.5 by an external vendor (AT&T.) How can remove the line from the config if I don't know the key? We have several other VPNs up and running, so I can just disable isakmp overall. I have tried changing the key, but that is not possible. In order to use the "no" command, I must know the key. Any suggestions?
Sample of config line:
isakmp key ******** address 220.127.116.11 netmask 255.255.255.255 no-xauth no-config-mode
