Default Setting

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 4-133), DHCP messages received on an untrusted interface (as 
specified by the 

no ip dhcp snooping trust

 command, page 4-134) 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, 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 a 

trusted

 

port. If the received packet is a DHCP ACK message, a dynamic DHCP 
snooping entry is also added to the binding table.

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

the DHCP packet is received, but the port is 

not trusted

, it is processed as 

follows:
* If the DHCP packet is a reply packet from a DHCP server (including 

OFFER, ACK or NAK messages), the packet is dropped.

* If the DHCP packet is from a client, such as a DECLINE or RELEASE 

message, the switch forwards the packet only if the corresponding entry 
is found in the binding table.

* If the DHCP packet is from client, such as a DISCOVER, REQUEST, 

INFORM, DECLINE or RELEASE message, the packet is forwarded if 
MAC address verification is disabled (as specified by the 

ip dhcp 

snooping verify mac-address

 command, page 4-135). However, if
