1.1 Port Binding Overview
A network administrator
can use the port binding feature to bind the MAC address and IP address of a
legal user to a specific port. With port binding, only the packets with the
specified MAC addresses and IP addresses can be transferred through the port.
This gives users enhanced control over network security.
