As you mentioned, configure your interface as layer 2 to see if your carrier's MAC address shows up. Configure interface-level packet-capturing ( ) and look at the capture offlineģ. Mirror that port and capture traffic with wireshark, orĢ. Therefore: If you want to analyze traffic that you are receiving from your carrier in an effort to troubleshoot then you should either:ġ. If there is a ip mismatch between you and your carrier then their IP and MAC will not show up in your ARP table. The only reason your router cares about MAC addresses in a layer 3 context is so it knows where to send either routed (to next-hop) or same-subnet packets to.
If your interface is configured as layer 3, your device will not maintain a list of MAC addresses outside of your subnet and you will not populate an ethernet table, even if one exists.
