We're applying port security to our LAN switches and when I try to do it on certain switch ports I get a message saying:

"GigabitEthernet1/1 is a dynamic port. port-security parameters cannot be set."

So what is does that mean - a dynamic port? When I do a "show mac address-table gi 1/1" it shows the port type as dynamic. On some other ports on which I've been able to set port security on it shows them as being static. But we've never configured these ports one way or the other.
