Figure 273 DHCP relay agent operation

Recommended configuration procedure

Task
Enabling DHCP and configuring
advanced parameters for the DHCP
relay agent
Creating a DHCP server group
Enabling the DHCP relay agent on an
interface
Configuring and displaying clients'
IP-to-MAC bindings
Remarks
Required.
Enable DHCP globally and configure advanced DHCP parameters.
By default, global DHCP is disabled.
Required.
To improve reliability, you can specify several DHCP servers as a
group on the DHCP relay agent and correlate a relay agent interface
with the server group. When the interface receives requesting
messages from clients, the relay agent forwards them to all the DHCP
servers of the group.
Required.
Enable the DHCP relay agent on an interface, and correlate the
interface with a DHCP server group.
IMPORTANT:
The DHCP relay agent works on interfaces with IP addresses manually
configured only.
Optional.
Create a static IP-to-MAC binding, and view static and dynamic
bindings.
The DHCP relay agent can dynamically record clients' IP-to-MAC
bindings after clients get IP addresses. It also supports static bindings,
that is, you can manually configure IP-to-MAC bindings on the DHCP
relay agent, so that users can access external network using fixed IP
addresses.
By default, no static binding is created.
