DHCP Snooping Commands

DHCP Snooping is a security feature that monitors DHCP messages between 

DHCP clients and DHCP server to filter harmful DHCP messages and build 

a bindings database of {MAC address, IP address, VLAN ID, interface} tuples 

that are considered authorized.
The DHCP snooping application processes incoming DHCP messages. For 

DHCPRELEASE and DHCPDECLINE messages, the application compares 

the receive interface and VLAN with the client's interface and VLAN in the 

bindings database. If the interfaces do not match, the application logs the 

event and drops the message. For valid client messages, DHCP snooping 

compares the source MAC address to the DHCP client hardware address. 

When there is a mismatch, DHCP snooping logs and drops the packet. 

DHCP Snooping forwards valid client messages on trusted members within 

the VLAN. If DHCP Relay and/or DHCP Server coexist with DHCP 

Snooping, the DHCP client message is sent to the DHCP Relay or/and 

DHCP Server for further processing.
The DHCP Snooping application uses DHCP messages to build and 

maintain the binding's database. The binding's database only includes data 

for clients on untrusted ports. DHCP Snooping creates a tentative binding 

from DHCP DISCOVER and REQUEST messages. Tentative bindings tie a 

client to a port (the port where the DHCP client message was received). 

Tentative bindings are completed when DHCP Snooping learns the client's IP 

address from a DHCP ACK message on a trusted port. DHCP Snooping 

removes bindings in response to DECLINE, RELEASE, and NACK messages. 

The DHCP Snooping application ignores the ACK messages as a reply to the 

DHCP Inform messages received on trusted ports. The network administrator 

can enter static bindings into the binding database.
IP Source Guard and Dynamic ARP Inspection use the DHCP Snooping 

bindings database for the validation of IP and ARP packets.
