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. Details available on http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCea37857 (need CCO login) Bottom line : Mind VLAN monitoring issues when using 10GE GSR LC. Vincent.
