Discussion on DHCP fault diagnosis process

We have explained a lot about the DHCP protocol and also learned about the DHCP service and related content of the DHCP server. Let's talk about some of its fault handling. This article mainly describes the settings of typical DHCP servers and the flowchart of DHCP fault diagnosis.

Typical Networking Environment

Before learning about DHCP fault diagnosis, let's take a look at the typical networking of the DHCP server, as shown in. The Fault Handling of DHCP servers based on the global address pool is based on this network.

In the following network diagram, the simplest solution is adopted. The client and server are in the same LAN, and GigabitEthernet1/0/0 is the connection interface between the server and the customer.

Configuration considerations 

DHCP fault diagnosis process

For the network shown in, the client cannot obtain the address after the global address pool is configured. Use the following fault diagnosis process, as shown in.
