All VLANs seem to drop the same size of packets

Hi all,   In our NNMi system we have some alarms that point all VLANS in our CGN are dropping the same size of packets. What can it be caused by?   Critical --X---- 10:03:2...

I agree with Cory... They are all inbound drops on every VLAN. So why is the box dropping them? One thought.... How would untagged packets be treated? Would they be "seen" and dropped by every VLAN? Just thinking out loud. Is there a native or untagged VLAN configured on the upstream switch? Also, could it be multicast traffic?

    This pretty much sums up exactly what I was thinking.
