Get List of Physical devices (Mac Address)

  • 1.  Get List of Physical devices (Mac Address)

    Posted 01-10-2022 06:34

    Is there a way to find the mac addresses "Connected" to each port on the switch.  I know I can find the "learned" mac addresses from the command show ethernet-switching table, but this seems to be not necessarily what device is connected to that port but whether that port has learned about that mac address.

    Here is a snippet of my output and as you can see, I have more than one mac address that is 'Learned' on port 1/0/32.

    VLAN             MAC address     Type       Age Interfaces
      FWSync2         *               Flood         - All-members
      FWSync2         00:00:00:00:fe:00 Learn         0 ge-1/0/33.0
      FWSync2         00:00:00:00:fe:01 Learn         0 ge-1/0/32.0
      FWSync2         00:01:00:00:fd:00 Learn         0 ge-1/0/32.0
      FWSync2         e4:43:4b:50:5c:7d Learn         0 ge-1/0/33.0
      FWSync2         e4:43:4b:53:0f:15 Learn         0 ge-1/0/32.0

    Unless....these initial entries are broadcasts?

    However I have entries like this and I know port 21 is not connected to another switch.

      tp-mpp-hosted-dmz 00:50:56:b0:09:52 Learn         0 ge-0/0/21.0

      tp-mpp-hosted-dmz 00:50:56:b0:0b:28 Learn       40 ge-0/0/21.0
