snooping bindings database, along with IPv6SG entries in the database, identify
authorized source IDs.
If you enable IPv6SG on a port on which DHCP snooping is disabled or on which DHCP
snooping is enabled but the port is untrusted, all IPv6 traffic received on that port is
dropped. In addition, IPv6SG interacts with port security (see Port security on page 704)
to enforce the source MAC address in incoming packets. Port security controls how
source MAC addresses are learned in the Layer 2 forwarding database (the MAC address
table). If a port receives a frame with a previously unlearned source MAC address, port
security uses IPv6SG to determine if the MAC address belongs to a valid binding.
