5.2.3.1 Managing Port Security
Network security can be increased by limiting access on a specic port only to users with specic MAC addresses. The MAC
addresses can be dynamically learned or statically congured. Locked port security monitors both received and learned
packets that are received on specic ports. Access to the locked port is limited to users with specic MAC addresses. These
addresses are either manually dened 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 conguration le. The MAC address list can be
restored after the device has been reset.
Disabled ports are activated from the Port Security Page.
