DHCP Layer 2 Relay Commands

In the majority of network configurations, DHCP clients and their associated
servers do not reside on the same IP network or subnet. Therefore, some kind
of third-party agent is required to transfer DHCP messages between clients
and 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 DHCP
server to a server or next-hop agent on another subnet. Unlike a router which
switches IP packets transparently, a DHCP Relay agent processes DHCP
messages and generates new DHCP messages as a result.
The PowerConnect DHCP Relay supports DHCP Relay Option 82 circuit-id
and remote-id for a VLAN.

Commands in this Chapter

This chapter explains the following commands:

dhcp l2relay (Global Configuration)

dhcp l2relay (Interface Configuration)
dhcp l2relay circuit-id
dhcp l2relay remote-id
dhcp l2relay trust
dhcp l2relay vlan
show dhcp l2relay all
show dhcp l2relay interface
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 when
the L2-DHCP Relay is enabled. Use the no form of this command to disable
L2-DHCP Relay.
