Port Binding Overview

Introduction

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 IP address are identical with the bound MAC address and IP address. This improves
network security and enhances security monitoring.
