Enabling DHCP Snooping on VLANS
DHCP snooping on VLANs is disabled by default. To enable DHCP snooping on a VLAN or range of
VLANs enter this command:
ProCurve(config)# dhcp-snooping vlan <vlan-id-range>
You can also use this command in the vlan context, in which case you cannot enter a range of VLANs
for snooping.
Below is an example of DHCP snooping enabled on VLAN 4.

Configuring DHCP Snooping Trusted Ports
By default, all ports are untrusted. To configure a port or range of ports as trusted, enter this
command:
ProCurve(config)# dhcp-snooping trust <port-list>
You can also use this command in the interface context, in which case you are not able to enter a list
of ports.
ProCurve(config)# dhcp-snooping vlan 4
ProCurve(config)# show dhcp-snooping
