Usage 
Information
When enabled, no learning takes place until you enable snooping on a VLAN. After 
disabling DHCP snooping, the binding table deletes and Option 82, IP Source 
Guard, and Dynamic ARP Inspection are disabled.
Introduced in Dell Networking OS version 7.8.1.0, DHCP snooping was available for 
Layer 3 only and dependent on DHCP Relay Agent (ip helper-address). Dell 
Networking OS version 8.2.1.0 extends DHCP Snooping to Layer 2. You do not 
have to enable relay agent to snoop on Layer 2 interfaces.

Enable DHCPv6 snooping globally for ipv6.
Syntax
