3.5 Troubleshooting DHCP Relay
I. Symptom
A client fails to obtain configuration information through a DHCP relay.
II. Analysis
This problem may be caused by improper DHCP relay configuration. When a DHCP
relay operates improperly, you can locate the problem by enabling debugging and
checking the information about debugging and interface state (You can display the
information by executing the corresponding display command.)
III. Solution
z Check if DHCP is enabled on the DHCP server and the DHCP relay.
z Check if an address pool that is on the same network segment with the DHCP
clients is configured on the DHCP server.
z Check if a reachable route is configured between the DHCP relay and the DHCP
server.
z Check the DHCP relay-enabled network devices. Check if the correct DHCP
server group is configured on the interface connecting the network segment
where the DHCP client resides. Check if the IP address of the DCHP server group
is correct.
