Layer 2 DHCP Snooping
By default, DHCP broadcasts are flooded on the default VLAN of the client/server port. If the DHCP
client and server are both members of the same VLAN domain, the broadcast packets from these sources
are bridged as Layer 2 traffic and not processed by the relay agent.
When DHCP Snooping is enabled at the switch level or for an individual VLAN, DHCP Snooping
functionality is also applied to Layer 2 traffic. When DHCP Snooping is disabled at the switch level or
disabled on the last VLAN to have snooping enabled on the switch, DHCP Snooping functionality is no
longer applied to Layer 2 or Layer 3 traffic.
