Thx for the hint, indeed "sh controllers gigabitEthernet 0/0" prints it. No mention of MAC .. in the output, but packets with all-zero DMAC are apparently counted both under .. hits as well as under Software filtered frames. In reality they pass through to L3 processing.

Hey, I'm not sure why this is relevant? OP is asking if frame should have passed PHY/mac_filter, If L3 port receives frame, it does not care about L2 headers, it'll just forward it based on L3, and generates new L2 rewrite on egress. Now should the router have received it or not is debatable. Te

Can you make a packet capture of the packet coming into the ingress interface and going out of the egress interface and share the capture with us? Then we can look for any differences in the packet (how the router may have changed it's contents). Also share the ingress and egress interface configs?
