Can someone tell me why some of the ports will not show the mac-add of the device plugged in even though the port status is up and shown traffic. but no mac-address

Thank you in advance.

Hello  Amks,

For example you may try:

show mac-address | i A2

This will show the device connected to port A2.

Hope this helps!

Edit: 

I tested on 2930 and it "show mac-address ethernet 1"  is working properly and showing the learned mac-address on the port. What is your device and software version.
