Re: Mac address not showing in show interface but is in table

We don't have that issue on our 3120s. We're running cbs31x0-universal-mz.122-46.SE.

You should be able to see the MAC address. The command you've input is also correct.

Hi, just curious...

Can you use "Gi1/0/14" in the interface command? It should work the way you did it, but Im just curious if its not a silly bug...

Thanks

cm.stk#sh mac address-table interface gi1/0/14
