DHCP Configuration

Overview of DHCP

DHCP enables a client to dynamically obtain a valid IP address from a server.

Configuration Precautions for DHCP

Configuring DHCP Relay

This section describes how to configure DHCP relay so that DHCP messages can be relayed between DHCP clients and the DHCP server that reside on different network segments.

Configuring a DHCP Server

A DHCP server selects available IP addresses from the global address pool and assigns these IP addresses to DHCP clients.

Configuring DHCP-PNP

This section describes how to configure Dynamic Host Configuration Protocol (DHCP) plug-and-play (PNP). DHCP PNP enables the network management system (NMS) to remotely configure and commission devices. This feature improves the working process and reduces operation and maintenance (O&M) costs.

Configuring a DHCP Client

With the DHCP client function configured, a device uses DHCP to dynamically request an IP address from the DHCP server. This achieves appropriate assignment and centralized management of IP addresses.

Maintaining a DHCP Client

Maintaining a DHCP client includes monitoring the running status of the DHCP client and clearing statistics on the DHCP client.

DHCP Server Maintenance

DHCP server maintenance includes monitoring the operating status of the DHCP server and clearing DHCP server statistics.

DHCP Relay Maintenance

DHCP relay maintenance includes monitoring the DHCP relay running status and clearing DHCP relay statistics and recording exchange information with the DHCP relay client.

Configuration Examples for DHCP

This section provides DHCP configuration examples, including networking requirements, networking diagram, configuration notes, configuration roadmap, and configuration procedure.
