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 trust B1-B2
ProCurve(config)# show dhcp-snooping
