I have an AP with two cables connected to it

I've noticed that the secondary port appears to be dropping RX packets.

Both ethernet ports appears to be in a bond0 interface. My concern is that this AP may be dropping packets and causing a bad experience for the clients connected to it. The counters are incrementing on the eth1 port so this is not static.
Has anyone else seen this happen before?
I can't find the eth1 MAC in my switched network so I'm having remote hands remove the cable as a test.
