IPv6 Source Guard is a security feature that filters IPv6 traffic on non-
routed, Layer 2 network interfaces based on manually configured entries in
the IPv6 Source Guard table, or dynamic entries in the Neighbor Discovery
Snooping table or DHCPv6 Snooping table when either snooping protocol is
enabled (see "DHCPv6 Snooping" on page
used to prevent traffic attacks caused when a host tries to use the IPv6
address of a neighbor to access the network. This section describes
commands used to configure IPv6 Source Guard.

mac-address - A valid unicast MAC address.
vlan-id - ID of a configured VLAN (Range: 1-4094)
ipv6-address - Corresponding IPv6 address. This address must be
