1.1 Port Binding Overview

Port binding enables the network administrator to bind the MAC address and IP

address of a user to a specific port. After the binding, the switch forwards only the

packets received on the port whose MAC address and IPaddress are identical with the

bound MAC address and IP address. This improves network security and enhances

security monitoring.
