Hey


I have a static vpn connection between to sites. Sometimes it seems that the connection goes down, just for som seconds, but it happens often.

I issued the command : sh crypto engine connections dropped-packet


an i got this output :


Packets dropped because of encapsulation/decapsulation failure:

Interface IP-Address Drop Count

FastEthernet0/0 x.x.x.x 1


Packets dropped because of abnormal event occurred:

Interface IP-Address Drop Count

FastEthernet0/0 x.x.x.x 7763


_______________________________


i checked the switch its connected to, and it doesent seem like the interface is flapping, ( i cant se any errors )


any suggestions how I proceed withe the troubleshooting ?


Thanks


-TH

Hi,


use some kind of "internet continuity" test between the two sites, like a continuous ping, what'up, etc. If you see "holes" in times corresponding with the VPN problems, you know that is caused by packet loss in the internet.


Hope this helps, please rate post if it does!
