Address Match Check

With this function enabled, the DHCP relay agent checks whether a requesting

client's IP and MAC addresses match a binding (dynamic or static) on the DHCP

 

relay agent. If not, the client cannot access outside networks through the DHCP

 

relay agent. This prevents invalid IP address configuration.

 

 

Server Group ID

A DHCP server group can be correlated with multiple interfaces.
