single mac statically bound to multiple ports?

[jgercken]

On the 2950 (SMI) is is possible to statically bind a single mac to >1 port? I didn't think this was possible but I don't have one to test.
int fa0/1
port-security mac-address <mac>
int fa0/2
port-security mac-address <mac>

thanks,
Jeff

Are you asking if it's possible to define the same mac address to more than one port on a switch? Why would you want to do that?

In a word, limiting multicasts w/o igmp/cgmp. I don't want to focus on the why, just want to know if it is possible.

No. You will mess up your MAC-ADDRESS-TABLE routing, and all requests will not be able to find the right port.

Example.

IP: 192.168.1.200 = MAC: 00:11:22:33:44:55

Port 22 on switch 192.168.1.5 = 00:11:22:33:44:55
Port 15 on switch 192.168.1.7 = 00:11:22:33:44:55

So when a request comes in for mac 00:11:22:33:44:55, which port does the switch send it to? It's the same problem as having a duplicate IP address on the network, the switch will not know what port to send it too.
