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:
HP Switch(config)# dhcp-snooping vlan <vlan-id-range>
You can also use this command in the vlan context, where you cannot enter a range of VLANs for
snooping.
