Solution: Command to view the mac address of the device itself

Commands to view the mac address of the device itself

For boxed devices, such as S2700/5700/S6700, you can view the mac address of the Layer 2 interface, which is the MAC of the device.

As follows, it is the mac address of the device: 1047-8031-bbd0

[S5700]display interface

Eth-Trunk0 current state : DOWN

Estado atual do protocolo de linha: DOWN

If it is an S9300 device, you can view it with the command display system-mac

<S9303>display system-mac

If you need to view the mac address of the attached device through the ip address, add a parameter to the dis arp command to see all the ip and mac addresses under a certain interface, the command is as follows:

<S_Buick>sys

Enter system view, return user view with Ctrl+Z.

[S_Buick]dis arp interface ethernet 0/0/36
