Untrust interface suddenly drops packet

Unanswered Question
May 31st, 2010


     Im having a weird case with my fwsm. There were times when the untrust interface suddenly drops all trafic, but after a few minutes it comes back again. I've already check the the np blocks, and it does not increment, thus proving that there are no oversubscription.

     Need your help here.



I have this problem too.

If as you say this is not related to hardware drops.

Things to see:

- syslogs

- which counters in "show np all stats" is increasing (clear np all stats, followed by "show np all stat | e _0_" during issue.

- are CAM/ARP tables stable (both switch/7600 and the FWSM) - the only reason I could see why it would actually drop for a while.

Wha are you running on the chassis and FWSM?
