A given port's (or a range of ports') dynamic MAC address
learning can be locked such that the current source MAC
addresses entered into the MAC address forwarding table
can not be changed once the port lock is enabled. Using the
Admin State pull-down menu to Enabled, and clicking
Apply can lock the port.
Port Security is a security feature that prevents unauthorized
computers (with source MAC addresses) unknown to the
Switch prior to locking the port (or ports) from connecting
to the Switch's locked ports and gaining access to the
network.
