4.9.7.3 DHCP Snooping VLAN Setting
Command Usage

When DHCP snooping is enabled globally on the switch, and enabled on the specified VLAN, DHCP packet filtering will be
performed on any untrusted ports within the VLAN.

When the DHCP snooping is globally disabled, DHCP snooping can still be configured for specific VLANs, but the changes
will not take effect until DHCP snooping is globally re-enabled.

When DHCP snooping is globally enabled, and DHCP snooping is then disabled on a VLAN, all dynamic bindings learned for
this VLAN are removed from the binding table.
