DHCP Snooping Configuration Commands

dhcp-snooping

Syntax

dhcp-snooping

undo dhcp-snooping

View

System view

Parameters

None

Description

Use the

dhcp-snooping

command to enable the DHCP snooping function.

Use the

undo dhcp-snooping

command to disable the DHCP snooping function. After DHCP

snooping is disabled, all the ports can forward DHCP replies from the DHCP server without recording

the IP-to-MAC bindings of the DHCP clients.

By default, the DHCP snooping function is disabled.

Note that:

You need to disable DHCP relay agent before enabling DHCP snooping on the switch.

The clients connected to a DHCP snooping device cannot obtain an IP address through BOOTP.

Related commands:

dhcp-server

display dhcp-snooping

Examples

# Enter system view.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

# Enable the DHCP snooping function.

[Sysname] dhcp-snooping

dhcp-snooping information enable

Syntax
