Hello,

 

Fortigate v7.2.9.

How can you display the MAC address table? I don't mean the arp table, I know the command.

 

get system arp

 

 

Thanks

Hi @AlbertMin ,

 

It depends on whether you are operating the FGT as Router mode or Transparent mode.

 

If it is Router mode, you can only run the ARP command to get the MAC info. Or using this command to get MAC info for interface individually:

 

diag hardware deviceinfo nic <Interface>

 

If it is TP mode, you may run the following command:

 

diag netlink brctl name host root.b    // If you have VDOM enabled, replace the root.b with the VDOM name as <Vdom_Name>.b

Hi Albert

Jerry is right, as per my knowledge we don't talk about mac address table on FGT in NAT mode (router mode), in this case we talk about arp table (MAC/IP pairs), like for any L3 host.

In transparent mode it is a L2 device, like a switch, and here it maintains a mac address table (IP/port pairs).
