"show mac-address-table" Vs "show mac address-table"

[akshaydeeti1996]

Hi,

Waiting for a quick help.

I have a Cisco switch. "show tech" command output contains "show mac-address-table" section with no mac address table entries underneath. When i run the "show mac-address-table" is gives "Invalid Command Output". But, when I run "show mac address-table" it gives mac address table entries.

So wondering on,

1. Difference between "show mac-address-table" and "show mac address-table" ?

2. Why "show tech" output is giving "show mac-address-table" section and no entries underneath ? 

Thank you.

show mac-address-table  - as i remember this was old code of IOS version

show mac address-table  - you need to use this command to see Layer 2 MAc address on the device.

Note : depends on what device you running this command have difference, if you using latest IOS and IOS XE you need to use show mac address-table

This command like a few others has Been updated or revised. Sometimes i think those revisions are mistakes. Someone has mistakenly changed it or made a typo that ended up in final IOS. 

Please always use ? Context sensitive help to fiulgure out command structure. 

I think show Mac is correct and recent while  mac-address-table is obsolete old IOS version 

Show tech is missing new and correct show Mac address command.
