two different MAC addresses on the same switchport
I have Catalyst 3750 running IOS version c3750-ipservicesk9-mz.122-55.SE.bin. I have an access port that connects to a Redhat Linux version 5.4 64 bits machine. When I perform a "show mac address-table interface g1/0/3" where the redhat machine is connected to, I see two mac addresses on this access port. One of the mac addresses, 0025.9006.4898, belongs the the redhat machine. the other mac address, I have no idea where it comes from. I tried to perform clear mac address-table dynamic g1/0/3 several times but it does not help either.
Anyone knows why I am seeing two different mac addresses on the same swithport?
Re: two different MAC addresses on the same switchport
did I mention that I built and maintained that Linux server ? I know it is a Super Micro Server.
I think I have an idea as to why I am seeing that MAC address. I think it is related to the DRAC/ILOM interface. With the DELL Enterprise DRAC uses separate LAN ports and add-in PCB but the low cost version does not. I suspect this is it but I will check a few more things to make sure that is the case.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
