Table 2-3 DHCP relay agent interface configuration items Item Interface Name DHCP Relay Address Match Check Server Group ID Description This field displays the name of a specific interface. Enable or disable the DHCP relay agent on the interface. Enable or disable IP address 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 via the DHCP relay agent. This prevents invalid IP address configuration. Correlate the interface with a DHCP server group. A DHCP server group can be correlated with multiple interfaces. Return to DHCP Relay Agent Configuration Task List. 2-5
