Command rejected: Not eligible for secure port.

I have loaded det newest ios in it, but it has det error stil.

Try typing in "switchport mode access" and then type in the port security command. Also look at the following bug

On the interface(s) you are trying to

turn port-security on first configure 'switchport mode access' - this will

stop the switchport from using DTP to try and negotiate a trunk - which

conflicts with the port-security command.
