Configuring Basic Functions of DHCP Snooping

Configuring Basic Functions of DHCP Snooping

Pre-configuration Tasks

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.

Before configuring DHCP snooping, configure the DHCP function. (For the DHCP configuration, see DHCP Configuration in the CloudEngine 8800, 7800, 6800, and 5800 Series Switches Configuration Guide - IP Services.)

Configuration Procedure

The basic function of DHCP snooping is configured on the Layer 2 access device or the first DHCP relay agent from the device.
