Mac-Address Question

[N W]

Hi All

I have a very easily answered question.

I have noticed on a 6509 I am working on, that when I do a "show mac-address interface gx/x" no mac address comes back.

If I do a show arp | i x.x.x.x the ip/mac shows up, and from there if I do a show mac-address address | i mac-address, I can see the mac against the interface. But it will still not show up under "show mac-address interface gx/x"

Any ideas as to why this would happen?

Cheers

HI Noel,

Is this happening only for one interface or all the interfaces?

I just check in my device and I am getting proper result:

HTTS-C6K1#sh mac address-table int g5/1

Legend: * - primary entry

        age - seconds since last seen

        n/a - not available

  vlan   mac address     type    learn     age              ports

------+----------------+--------+-----+----------+--------------------------

Active Supervisor:

*  599  aca0.160a.dcc0   dynamic  Yes          0   Gi5/1

C6K1#sh mac

C6K1#sh mac add

C6K1#sh mac address-table | in  aca0.160a.dcc0

*  599  aca0.160a.dcc0   dynamic  Yes          5   Gi5/1

C6K1#

Can you try to ping any other device from the pc / device connected to this interface and check??

HTH
