5.17. DHCP Snooping Commands
DHCP snooping is a security feature that monitors DHCP messages between a DHCP client and DHCP servers to
filter harmful DHCP messages and to build a bindings database of {MAC address, IP address, VLAN ID, port}
tuples that are considered authorized. You can enable DHCP snooping globally and on specific VLANs, and
configure ports within the VLAN to be trusted or untrusted. DHCP servers must be reached through trusted
ports.
The DHCP snooping binding table contains the MAC address, IP address, lease time, binding type, VLAN number,
and interface information that corresponds to the local untrusted interfaces of a switch; it does not contain
information regarding hosts interconnected with a trusted interface. An untrusted interface is an interface that
is configured to receive messages from outside the network or firewall. A trusted interface is an interface that is
configured to receive only messages from within the network.
DHCP snooping acts like a firewall between untrusted hosts and DHCP servers. It also gives you a way to
differentiate between untrusted interfaces connected to the end-user and trusted interfaces connected to the
DHCP server or another switch.
DHCP snooping enforces the following security rules:
DHCP packets from a DHCP server (DHCPOFFER, DHCPACK, DHCPNAK, DHCPRELEASEQUERY) are dropped if
received on an untrusted port.
DHCPRELEASE and DHCPDECLINE messages are dropped if for a MAC address in the snooping database, but the
binding's interface is other than the interface where the message was received.
On untrusted interfaces, the switch drops DHCP packets whose source MAC address does not match the client
hardware address. This feature is a configurable option.
The hardware identifies all incoming DHCP packets on ports where DHCP snooping is enabled. DHCP snooping is
enabled on a port if (a) DHCP snooping is enabled globally, and (b) the port is a member of a VLAN where DHCP
snooping is enabled. On untrusted ports, the hardware traps all incoming DHCP packets to the CPU. On trusted
ports, the hardware forwards client messages and copies server messages to the CPU so that DHCP snooping can
learn the binding.
You can enable the switch to operate as a DHCP Layer 2 relay agent to relay DHCP requests from clients to a
Layer 3 relay agent or server. The Circuit ID and Remote ID can be added to DHCP requests relayed from clients
to a DHCP server. This information is included in DHCP Option 82, as specified in sections 3.1 and 3.2 of
RFC3046.
