DHCP Snooping Commands

DHCP snooping allows a switch to protect a network from rogue DHCP servers or
other devices which send port-related information to a DHCP server. This
information can be useful in tracking an IP address back to a physical port. This
section describes commands used to configure DHCP snooping.  

ip dhcp snooping

This command enables DHCP snooping globally. Use the 

no

 form to restore the

default setting.

Syntax

Command Mode

Global Configuration

Command Usage 

• Network traffic may be disrupted when malicious DHCP messages are

received from an outside source. DHCP snooping is used to filter DHCP
messages received on an insecure interface from outside the network or fire
wall. When DHCP snooping is enabled globally by this command, and
enabled on a VLAN interface by the 

ip dhcp snooping vlan

 command

(page 4-146), DHCP messages received on an untrusted interface (as
specified by the 

no ip dhcp snooping trust

 command, page 4-147) from a

device not listed in the DHCP snooping table will be dropped. 

• When enabled, DHCP messages entering an untrusted interface are filtered

based upon dynamic entries learned via DHCP snooping.

• Table entries are only learned for untrusted interfaces. Each entry includes a
