Introduction

Binding is a simple security mechanism. Through the binding configuration on the switch, you can filter
the packets forwarded on the ports. When a port receives a packet, it searches the binding entry. If the
information carried in the packet matches the information in the binding entry, the port forwards the
packet. Otherwise, the port discards the packet.
Currently, the switch provides the following binding policies:
Port-IP binding: binds a port to an IP address. On the bound port, the switch forwards only the
packets sourced from the bound IP address.
Port-MAC binding: binds a port to a MAC address. On the bound port, the switch forwards only the
packets sourced from the bound MAC address.
Port-MAC-IP binding: binds a MAC address and an IP address to a port. On the bound port, the
switch forwards only the packets sourced from the bound MAC address and IP address
combination.
IP-MAC binding: binds an IP address to a MAC address. The switch forwards only the packets
sourced from the bound source MAC address and source IP address.
When a port is bound, the binding applies only to the port.
