Show mac address by physical port

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

the problem with is that it does not say what NIC is connected to where.

AFAIK you can only see direct partner's MAC in LACP bundles.

Hello to all

 

The previous doesn´t work for me, I´m looking for something like:

 

**************************************************************************

CISCO_SWITCH#sh mac address-table interface GigabitEthernet1/0/1           Mac Address Table ------------------------------------------- Vlan    Mac Address       Type        Ports ----    -----------       --------    ----- CISCO_SWITCH#sh mac address-table interface GigabitEthernet1/0/24           Mac Address Table ------------------------------------------- Vlan    Mac Address       Type        Ports ----    -----------       --------    -----  201    FFFF.FFFF.FFFF DYNAMIC     Gi1/0/24  204    FFFF.FFFF.FFFF DYNAMIC     Gi1/0/24 Total Mac Addresses for this criterion: 2 CISCO_SWITCH#

 

With this output I can know that there are 2 devices connected to that port in particular

**************************************************************************

 

**************************************************************************

"get hardware nic wan1" display the port mac not the mac addresses that are connected to that port:

Not sure about the CLI, but you can see what MACs are connected to the interface via the GUI. 

 

On 5.2.X:

User & Device > Device > Device Definitions.

 

If nothing is showing you need to enable device identification on the interface.

#config system interface

#edit port1

#set device-identification enable

If logical port is all we've got IMHO that's not that bad...I think they comprise physical and virtual ports (VLAN etc.).

I'd combine the CLI command with a grep:

get sys arp | grep port10
