Port Security Commands
These commands can be used to enable port security on a port. When using port
security, the switch stops learning new MAC addresses on the specified port when it
has reached a configured maximum number. Only incoming traffic with source
addresses already stored in the dynamic or static address table for this port will be
authorized to access the network. The port will drop any incoming frames with a
source MAC address that is unknown or has been previously learned from another
port. If a device with an unauthorized MAC address attempts to use the switch port,
the intrusion will be detected and the switch can automatically take action by
disabling the port and sending a trap message.
