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.
ipv6 dhcp snooping
Enable DHCPv6 snooping globally for ipv6.
Syntax
[no] ipv6 dhcp snooping
To disable the snooping globally, use the no ipv6 dhcp snooping command.
Defaults Disabled
