Please view the attachment. I have several servers connected to a Cisco 4506. When I perform a #show mac-address interface g2/2 a unicast mac-address show up, which is normal behavior. On other ports when I run the same command a unicast mac does NOT appear. I get all ffffffffffffff. No users are reporting issues. Why don't I see a unicast mac on each port and what does the all f f f f f f f  with the listing of port numbers? Thanks in advance.

Looks like a bug to me. Have you try a newer IOS to see if the problem still persist?
