Chapter 15 Binding Table Commands
You can bind the IP address, MAC address, VLAN and the connected Port number of the Host

packets.
15.1 ip source binding
Description
The ip source binding command is used to bind the IP address, MAC address,
VLAN ID and the Port number together manually.
You can manually bind the IP

IP-MAC–VID-PORT entry from the binding table, please use no ip source
binding index command.
