Dhcp Configuration - Huawei S9300 Configuration Manual

S9300&S9300E Terabit Routing Switch
Configuration Guide - IP Service
About This Chapter
The DHCP technology is applicable to a variety of networks. It ensures proper IP address
allocation and saves IP addresses on networks.
3.1 Introduction to DHCP
Dynamic Host Configuration Protocol (DHCP) enables a client to dynamically obtain a valid IP
address.
3.2 DHCP Features Supported by the S9300&S9300E
The S9300&S9300E can be used as a DHCP server or a DHCP relay agent.
3.3 Configuring the DHCP Server Based on the Global Address Pool
A DHCP server can allocate IP addresses to clients by using the global address pool.
3.4 Configuring the DHCP Server Based on the VLANIF Interface Address Pool
If a DHCP server based on a VLANIF interface address pool is configured, all the users going
online through this interface obtain IP addresses from the VLANIF interface address pool.
3.5 Configuring the DHCP Relay Agent
By using a DHCP relay agent, the DHCP clients on a local area network (LAN) can communicate
with the DHCP servers on other network segments, and obtain IP addresses from them. The
DHCP clients on different network segments can also use one DHCP server. This reduces costs
and achieves centralized device management.
3.6 Maintaining DHCP
After DHCP configurations are complete, you can clear DHCP statistics and monitor DHCP
operation.
3.7 Configuration Examples
DHCP configuration examples explain the networking requirements, networking diagram,
configuration notes, configuration roadmap, and configuration procedure. The configuration
examples involve various usage scenarios of DHCP.
