Usage guidelines

This command enables DHCPv6 snooping to record IPv6 prefix-to-port information of the DHCPv6 clients (called DHCPv6 snooping prefix entries). When IP source guard (IPSG) is configured on the DHCP snooping device, IPSG can generate dynamic bindings based on the DHCP snooping prefix entries to filter out illegitimate packets.

If you configure this command in a VSI view, this command takes effect on the ACs that are mapped to the VSI and the VXLAN tunnel interfaces that are assigned to the VSI.
