DHCP Snooping

– 242 –

DHCP Snooping

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

[

no

]

ip dhcp snooping

Default Setting

Disabled

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 unsecure 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, DHCP messages received on

Table 50: DHCP Snooping Commands
