Port Security

Port Security
port security
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.
