ip dhcp snooping

Use this command to globally enable DHCP snooping. Use no command to 
disable DHCP snooping.

ip dhcp snooping

no ip dhcp snooping

Syntax

None

Default

Disabled

Command Mode

Global configuration

Usage Guideline

The DHCP snooping function snoops the DHCP packets arriving at the un-
trusted interface on VLAN that is enabled for DHCP snooping. With this function, 
the DHCP packets coming from the un-trusted interface can be validated, and a 
DHCP binding database will be constructed for the DHCP snooping enabled 
VLAN. The binding database provides IP and MAC binding information that can 
be further used by the IP source guard and dynamic ARP inspection process. 

Use the ip dhcp snooping command to globally enable DHCP snooping. Use the 
ip dhcp snooping vlan command to enable DHCP snooping for a VLAN.  DHCP 
snooping process occurs during the relay agent relays the packet. To enable the 
DHCP relay service, relay agent service must be enabled by service dhcp 
command, and the server address to relay the packet must be configured by the 
ip dhcp relay address. 

Example

These examples shows how to enable and disable DHCP snooping:

Switch# configure terminal
Switch(config)# ip dhcp snooping
Switch(config)#

-------------------------------------------

Switch# configure terminal
Switch(config)# no ip dhcp snooping
