Cisco – How to show Mac Address of Interface

There are a few ways of getting the MAC address into from a Cisco device. The option to get a MAC address that requires the absolute least amount of typing is:

• en
• conf t
• show int fa0/0

This will spew a whole ton of info. The only issue with this option is there is too much info and sometimes finding what you are looking for is harder than it needs to be.

My prefered way of getting the MAC address of the interface is by using this command.

• en
• conf t
• show int fa0/0 | in Hardware

Let’s go over the last line shall we? It reads… Show interface Fa0/0 … Take that info pipe it.. and display the info in Hardware section.

Like I said earlier I much prefer the last output. The only gotcha is making sure that you use a “H” instead of a “h” in “Hardware”. Case DOES matter!
