Use the no form of this command to not process DHCP unicast packets. ip dhcp relay unicast no ip dhcp relay unicast Parameters None. Default By default, DHCP client unicast packets will be relayed. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is used to enable or disable the DHCP relay and local relay agent to process DHCP unicast packets. Unicast includes all DHCP client message types like DHCP renew, release, and more. When several devices enable the relay state in the topology, the unicast state should be same. DHCP relay will not check if the VRRP role is master or slave when relaying the packet. It will always be relayed from the first relay agent because DHCP discovery cannot determine the VRRP master. Example This example shows how to enable the Switch to process DHCP client unicast packets. Switch# configure terminal Switch(config)# ip dhcp relay unicast Switch(config)# 191
