Hello

 

In cisco switches you are able to "show" mac address by port with "show mac address-table interface gigabitEthernet0/1" it is possible to do the same in a Fortigate appliance?

 

Thanks

    Hi,

    how about to "see" the mac address where it is connected to?

    That would make my network "mapping" a lot easier.

    Why not ask for the arp table right away?

    diag ip arp list

    get sys arp

    @huutrung07 You won't see the Cisco MAC or ARP Tables on your Fortigate with this setup.

     

    You say you've set up the Cisco as a layer 3 router not a layer 2 switch.  None of the MAC information will be passed to the Fortigate in a routed environment.

    diag switch-controller mac-cache show 

     

    It will show you each switch (Serial Number) then what vlan id , prot and mac address of the device if connected. 

     

    It also shows when it was last seen on the port.
