Port Security
Port security is a feature that allows you to configure a port with one or
more MAC addresses that are authorized to access the network through
that port.
When port security is enabled on a port, 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 will be accepted as authorized
to access the network through that 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 as specified by the
Intrusion Action attribute.
Note: Port security only addresses dynamically learned MAC addresses
and has no limitations on static MAC addresses. On this switch, 24
static MAC address can be configured by System > Static MAC
