Port binding allows the network administrator to bind the MAC and IP addresses 
of a user to a specific port. After the port binding operation, the switch forwards a 
packet received from the port only if the source MAC address and IP address 
carried in the packet have been bound to the port. This improves network security 
and enhances security monitoring.
