David,
I don't believe that is the correct assumption, but I could be wrong.
Are you sure that that MAC doesn't currently live on another port right
now? I am assuming that the MAC might either be tied to another port via
dynamic (plugged into) or port security turned up for it on another
port. - Just a guess.
Thanks,
scott

Subject: Port-Security Error Message
When I do this...
int fast 0/0
switchport port-security
switchport port-security mac-address 0010.7b36.7ccc
I get this..
%Error: Address 0010.7b36.7ccc already exists.
I believe this is because by default, port-security on the 3550 accepts
128
secure mac-addresses and will learn dynamically the mac-address of the
device connected to that port. Therefore, there is no need to specify
port-security mac-address since it is dynamically learned.
Can anyone else confirm why that message comes up?
