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 

an untrusted interface (as specified by the 

no ip dhcp snooping trust

 

command) 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 trusted interfaces. Each entry includes a MAC 
address, IP address, lease time, 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.
