DHCP Clear Commands
Configure the System to be a Relay Agent
DHCP clients and servers request and offer configuration information via broadcast DHCP messages.
Routers do not forward broadcasts, so if there are no DHCP servers on the subnet, the client does not
receive a response to its request and therefore cannot access the network.
You can configure an interface on the Dell Force10 system to relay the DHCP messages to a specific
DHCP server using the command
ip helper-address dhcp-address from INTERFACE mode, as shown in
the following figure. Specify multiple DHCP servers by entering the
ip helper-address dhcp-address
command multiple times.
3 Specify the client hardware address or
client-identifier.
hardware-address is the client
MAC address.
client-identifier is required for
Microsoft clients instead of a hardware
addresses. The client identifier is
formed by concatenating the media
type and the MAC address of the client.
Refer to the “Address Resolution
Protocol Parameters” section of RFC
1700—Assigned Numbers, for a list of
media type codes.
