I've noticed a strange behaviour of our FWSM (Release 3.1.3). When starting the ASDM or using CLI (show interface XY stats), both ways show the same amount of traffic. It's the same amount of traffic the 6513 router beyond also measures.
But when i try to use SNMP on the OIDs ifOutOctets/ifInOctets, i get way too little traffic. Also the packet counter shows way too little packets than i get via CLI or the ASDM frontend.
Is it a bug of the firmware or does the FSWM count the traffic and packets in a different way?
Can someone please verify this?
