23-20

from a DHCP server, any packets received from untrusted ports are

dropped.

Example

This example enables DHCP snooping globally for the switch.

Related Commands

ip dhcp snooping vlan (23-20)

ip dhcp snooping trust (23-24)

ip dhcp snooping vlan

This command enables DHCP snooping on the specified VLAN. Use the

no form to restore the default setting.

Syntax

[no] ip dhcp snooping vlan vlan-id

vlan-id - ID of a configured VLAN (Range: 1-4093)

Default Setting

Disabled

Command Mode

Global Configuration

Command Usage

• When DHCP snooping enabled globally using the ip dhcp snooping

command (page23-18) , and enabled on a VLAN with this command,

DHCP packet filtering will be performed on any untrusted ports

within the VLAN as specified by the ip dhcp snooping trust

command (page 23-24).

• When the DHCP snooping is globally disabled, DHCP snooping can

still be configured for specific VLANs, but the changes will not take

effect until DHCP snooping is globally re-enabled.
