Debugging Site to Site VPN connection

Debugging specific Peer IP Address.

debug crypto condition peer 192.168.1.5

The above command will only generate debug on Peer IP address of 192.168.1.5.  When you’re done, run debug crypto condition reset to undo the command above.

Run debug crypto isakmp 127 (phase 1) or debug crypto ipsec 127 (phase 2) to generate debug information. Run undebug all to stop all debug information.
