ip dhcp snooping

This command enables DHCP snooping globally. Use the no form to restore the 
default setting.

Syntax

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 
firewall. When DHCP snooping is enabled globally by this command, and 
enabled on a VLAN interface by the 

ip dhcp snooping vlan

 command (page 

4-230

), DHCP messages received on an untrusted interface (as specified by 

the 

no ip dhcp snooping trust

 command, page 

4-230

) 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 

MAC address, IP address, lease time, entry type (Dynamic-DHCP-Binding, 
Static-DHCP-Binding), VLAN identifier, and port identifier.

• When DHCP snooping is enabled, the rate limit for the number of DHCP 

messages that can be processed by the switch is 100 packets per second. 
Any DHCP packets in excess of this limit are dropped.

• Filtering rules are implemented as follows:

- If the global DHCP snooping is disabled, all DHCP packets are 

forwarded.

- If DHCP snooping is enabled globally, and also enabled on the VLAN 

where the DHCP packet is received, all DHCP packets are forwarded for
