What is port congestion?

what is Congestion Port ? what is the normal value of per port?

I have seen certain devices that work better with jumbo-frames enabled - check out the documentation here it can explain it:http://documentation.extremenetworks.com/exos/EXOS_All/Slots_and_Ports/c_jumbo-frames.shtml

Aruba is a wireless manufacturer.

I would enable jumbo-frames, clear counters and see if it makes any difference.

Munir,

The congestion output looks to be very close as far as the amount of dropped packets on those ports. This would indicated that you may have some type of flooding occurring such as broadcast or unicast.

As Patrick mentioned, I would clear out these counters and start from zero. Keep an eye on them and if they are increasing at a similar rate, mirror one of the ports ingress and egress to see what the majority of traffic is. Broadcast traffic will of course flood to every port in the vlan but unicast traffic should only be sourced or destined from the device on that port (you should not see unicast traffic egress that port with a destination mac other that the mac that shows in show fdb port <#> output.

Cheers!

Yes, hitting the "0" (Zero) key while the output is being displayed will clear the counters. You can also run the command "clear counters".
