The DHCP snooping feature performs the following activities: •Validates DHCP messages received from untrusted sources and filters out invalid messages. •Rate-limits DHCP traffic from trusted and untrusted sources. •Builds and maintains the DHCP snooping binding database, which contains information about untrusted hosts with leased IP addresses. •Utilizes the DHCP snooping binding database to validate subsequent requests from untrusted hosts. Other security features, such as dynamic ARP inspection (DAI), also use information stored in the DHCP snooping binding database. DHCP snooping is enabled on a per-VLAN basis. By default, the feature is inactive on all VLANs. You can enable the feature on a single VLAN or a range of VLANs. The DHCP snooping feature is implemented in software on the route processor (RP). Therefore, all DHCP messages for enabled VLANs are intercepted in the PFC and directed to the RP for processing. Trusted and Untrusted Sources The DHCP snooping feature determines whether traffic sources are trusted or untrusted. An untrusted source may initiate traffic attacks or other hostile actions. To prevent such attacks, the DHCP snooping feature filters messages and rate-limits traffic from untrusted sources. In an enterprise network, devices under your administrative control are trusted sources. These devices include the switches, routers, and servers in your network. Any device beyond the firewall or ou
