Hi,

The port has to receive traffic on the port before it will put the MAC address in the table. Possible reasons..no IP address on the system, wrong IP address on the system.

This is a common occurance when you are talking about a host/server who's probably got network "teaming" or "floating" interface configured.

It also happens, for instance, if a host is powered off but power is still provided by means of the wall socket.

I had the exact same problem yesterday, I rebooted the switch and it fixed the problem.
