◆

When DHCP snooping is enabled, DHCP messages entering an untrusted interface are

filtered based upon dynamic entries learned via DHCP snooping.

◆

Filtering rules are implemented as follows:

■ If the global DHCP snooping is disabled, all DHCP packets are forwarded.

■ If DHCP snooping is enabled globally, 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, 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 a DHCP DECLINE or RELEASE message is received from a client, the switch
forwards the packet only if the corresponding entry is found in the binding table.

■ If a DHCP DISCOVER, REQUEST or INFORM message is received from a client, the
packet is forwarded.

■ If the DHCP packet is not a recognizable type, it is dropped.

■ If a DHCP packet from a client passes the filtering criteria above, it will only be
forwarded to trusted ports in the same VLAN.

■ If a DHCP packet is from server is received on a trusted port, it will be forwarded to both
trusted and untrusted ports in the same VLAN.

■ If the DHCP snooping is globally disabled, all dynamic bindings are removed from the
binding table.

■ Additional considerations when the switch itself is a DHCP client – The port(s) through
which the switch submits a client request to the DHCP server must be configured as

trusted. Note that the switch will not add a dynamic entry for itself to the binding table

when it receives an ACK message from a DHCP server. Also, when the switch sends out

DHCP client packets for itself, no filtering takes place. However, when the switch receives

any messages from a DHCP server, any packets received from untrusted ports are

dropped.

PARAMETERS

These parameters are displayed:

◆

Snooping Mode

– Enables DHCP snooping globally. When DHCP snooping is enabled,

DHCP request messages will be forwarded to trusted ports, and reply packets only

allowed from trusted ports. (Default: Disabled)

◆

Port

– Port identifier

◆

Mode

– Enables or disables a port as a trusted source of DHCP messages. (Default:

Trusted)
