Packet drop on FWSM L3 interface.

madhusudhan s · ‎01-18-2010

Hi,

My FWSM cpu/memory utilization is quite normal, but when i checked the the VLAN interfaces configured on FWSM , i find lots of packet drop.

There are more then 20 VLAN interface defined in FWSM. I am suspecting high load between FWSM and switch through etherchannel port-channel which automatically configured when we install FWSM in switch, but dont the command to verify the actual load . can some1 help in solving this issue.

Thanks & regards

On the FWSM:

clear traffic

sh traffic

sh np blocks (couple of times to see if the counter increments)

On the switch:

show int po 270 counters etherchannel

where 270 is from the output of the command "sh etherchannel sum" the etherchannel that the FWSM creates with the switch on the back end.
