User Guidelines
Traffic is filtered based upon the source IPv6 address and VLAN. Use the
switchport port-security command in interface mode to optionally add MAC
address filtering in addition to source IPv6 address filtering. If port security is
enabled, the filtering is based upon IPv6 address, MAC address and VLAN.
ipv6 verify source
Use the ipv6 verify source command to configure an interface to filter (drop)
incoming traffic from sources that are not present in the DHCP binding
database. Use the no form of the command to enable unverified traffic to
flow over the interfaces.
