Question : Problem: Pix 515 isakmp password

We are in the process of resetting up a Pix 515 to Pix 501 VPN tunnel.  The creator of the original key is no longer accessable, and we are having trouble resetting the isakmp key on the 515.  Ive tried the "no" command with no luck, and tried resetting it using "isakmp key blahblah address 0.0.0.0 netmask 0.0.0.0"  

I get the message,

"A preshared key for address 0.0.0.0 netmask 0.0.0.0 already exists!"

Any suggestions on how to view the old key, or change it to a new one would be much appreciated as this is a time sensitive and urgent (to us) situation.

Answer : Problem: Pix 515 isakmp password

Hi fulcherjl,
         In order to see the old key.
1. Copy the running config to tftp server, by "write net [tftp_server_ip] : [filename]
2. Go to tftp server and open the saved file with word pad. Look for the isakmp key command again.

         To reset key, "no" is the correct answer unless u miss out some word or mis spelling

         "A preshared key for address 0.0.0.0 netmask 0.0.0.0 already exists!" bcoz u are keying the same key as it already is in running config.

Last, PDM will be the easier way to change key w/o understanding the config. Let us know if u need more information.

Good Luck
