I was wondering :

We recently installed 10GE interface on GSR boxes (Engine4+).

I are experiencing a SNMP counter issue with 802.1q VLAN.

We were used to have counters by 802.1q VLAN on GSR on 1GE, but it looks to be broken for 10GE subinterfaces.

Counters are available by SNMP, but are buggy on Inbound.

ifHCInUcastPkts is OK, but ifHCInOctets is not.

Does anyone experienced such problem on 10GE with GSR ? Counters from physical interace are fine. We experiences this on SubInterfaces only.

Thanks to nanog community, i had positive feedbacks. This is hardware limitation with 10GE cisco Card on GSR. Since it look to be an ASIC issue, i do not expect to be fixed by software !! There is a workaround to get byte counter, but we have to disable packet counter. This is what we did and it works fine.
