Packet check principles
Switch B checks DHCPv6 protocol packets from DHCPv6 clients against link-local address ND snooping
entries; checks ND protocol packets against ND snooping entries, DHCPv6 snooping entries, and static
binding entries; and checks the IPv6 data packets from the hosts against dynamic binding entries
(including ND snooping entries and DHCPv6 snooping entries) applied on the interfaces connected to
the hosts and against static binding entries. The items to be examined include MAC address, IPv6
address, VLAN information, and ingress port.
