Hey Steve, Thanks for the response. Since you also have this problem, we won't pursue the matter with Cisco as a bug. And again, I only see this problem on 2 of our new switches, not the dozen+ older cisco switches we have. I'll just Target the ifInOctets twice.
Even more strange, these switches don't have ifOutOctets entries but the do have ifOutUcastPkts entries for unrouted vlans. And yes, ifOutUcastPkts = ifInUcastPkts.
