Re: OT: Mac-address Table on Catalyst 6509 with SFP fibre

Hello Sadiq,

I used the command you suggested but without the 'all' option. Find below
the output.

CAT6509#sh mac-address-table interface g1/2
Displaying entries from Line card 1:

Legend: * - primary entry
        age - seconds since last seen
        n/a - not available

  vlan mac address type learn age ports
------+----------------+--------+-----+----------+--------------------------
* 15 0011.25bd.632f dynamic Yes 0 Gi1/2

CAT6509#

Regards,

Mayokun
