3.7(1)ES1

Description (partial)

Symptom:
In our case as we have seen the packets are getting dropped due to the "L3_NOT_MYMAC"  NP counter. This is because at the point in capture these 2 counters are same. The RESOLVE_INGRESS_DROP_CNT   is an aggregate counter and hence I looked into what individual counter may be the cause. Hence In our case they are dropped by the fact that packets received with a dmac that is not in our ?listen? table as well as some other unrecognized protocols.

32  RESOLVE_INGRESS_DROP_CNT                           979566644

328  L3_NOT_MYMAC                                       979566646

L3_NOT_MYMAC       A layer3 unicast IPV4/IPV6 frame does not have the destination mac address of the router. These are dropped.
