Port Binding Overview
Introduction Port binding enables the network administrator to bind the MAC address and IP
address of a user with a specific port. After the binding, the switch forwards only
the packets received on the port whose MAC address and IP address are identical
with the bound MAC address and IP address. This improves network security and
enhances security monitoring.
