Description (partial)

On a mixed F2e & M1 VDC, an L2 packet with a known destination MAC address that is received by an F2e port can get incorrectly proxied to the M1 module. This will cause the packet to be dropped on the egress module.

This was observed on N7k mixed VDC running 6.2(6a). Other releases can be affected as well.

Other conditions are unknown at this point.
