5.2.3.1 Managing Port Security
Network security can be increased by limiting access on a specific port only to users with specific MAC addresses. The MAC
addresses can be dynamically learned or statically configured. Locked port security monitors both received and learned
packets that are received on specific ports. Access to the locked port is limited to users with specific MAC addresses. These
addresses are either manually defined on the port, or learned on that port up to the point when it is locked. When a packet
is received on a locked port, and the packet TP-Link source MAC address is not tied to that port (either it was learned on a
different port, or it is unknown to the system), the protection mechanism is invoked, and can provide various options.
Unauthorized packets arriving at a locked port are either:
Forwarded

Discarded with no trap

Discarded with a trap

Shuts down the port

Locked port security also enables storing a list of MAC addresses in the configuration file. The MAC address list can be
restored after the device has been reset.
Disabled ports are activated from the Port Security Page.
