DHCP Layer 2 Relay Commands 3299DHCP Layer 2 Relay CommandsIn the majority of network configurations, DHCP clients and their associatedservers do not reside on the same IP network or subnet. Therefore, some kindof third-party agent is required to transfer DHCP messages between clientsand servers. Such an agent is known as a DHCP Relay agent.The DHCP Relay agent accepts DHCP requests from any routed interface,including VLANs. The agent relays requests from a subnet without a DHCPserver to a server or next-hop agent on another subnet. Unlike a router whichswitches IP packets transparently, a DHCP Relay agent processes DHCPmessages and generates new DHCP messages as a result.The PowerConnect DHCP Relay supports DHCP Relay Option 82 circuit-idand remote-id for a VLAN.Commands in this ChapterThis chapter explains the following commands:dhcp l2relay (Global Configuration)Use the dhcp l2relay command to enable Layer 2 DHCP Relay functionality.The subsequent commands mentioned in this section can only be used whenthe L2-DHCP Relay is enabled.
