nd snooping enable

[Command] nd snooping enable no nd snooping enable

[Purpose] Enable ND snooping function globally

[View] System configuration view, Interface view, VLAN Interface view

[Notes] After ND Snooping is enabled on the device, the interface with ND Snooping enabled will learn the ND Snooping table entry when it receives NS packets from DAD. If the device is enabled with SAVI and IPSGv6, the ND and DHCPv6 packets will be matched according to the ND Snooping table entry. After enabling the global ND Snooping function, user also need to enable the ND Snooping function under the interface and Vlan view.
