Port Security Commands

AUTHENTICATION COMMANDS

These commands can be used to disable the learning function or manually specify secure addresses for a port. You may want to leave port security off for an initial training period (i.e., enable the learning function) to register all the current VLAN members on the selected port, and then enable port security to ensure that the port will drop any incoming frames with a source MAC address that is unknown or has been previously learned from another port.
