Step Remarks
3. Enabling the DHCP relay agent
Required.
Enable the DHCP relay agent on an interface, and correlate the
interface with a DHCP server group.
With DHCP enabled, interfaces work in the DHCP server mode by
default.
IMPORTANT:
•
An interface cannot serve as both the DHCP server and the DHCP
relay agent. The latest configuration takes effect.
•
If the DHCP relay agent is enabled on an Ethernet subinterface, a
packet received from a client on this interface must contain a VLAN
tag and the VLAN tag must be the same as the VLAN ID of the
subinterface; otherwise, the packet is discarded.
•
The DHCP relay agent works on interfaces with IP addresses
manually configured only.
•
If an Ethernet subinterface serves as a DHCP relay agent, it conveys
IP addresses only to subinterfaces of DHCP clients. In this case, a
PC cannot obtain an IP address as a DHCP client.
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.
In other words, 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.
