Configuring Basic Functions of DHCP Snooping

DHCP snooping allows DHCP clients to obtain IP addresses from authorized DHCP servers, and records mappings between IP addresses and MAC addresses of DHCP clients to a binding table.

Pre-configuration Tasks

Before configuring DHCP snooping, configure the DHCP function. (For the DHCP configuration, see DHCP Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - IP Service.)

Configuration Procedure

Configure basic functions of DHCP snooping on a Layer 2 access device or the first DHCP relay agent from the device.
