IPv6 traffic on an interface.

You can use the ipv6 traffic-filter command on physical interfaces (Layer 2 or Layer 3 ports), Layer 3

inbound filtering on Layer 2 ports (port ACLs).
If any port ACL (IPv4, IPv6, or MAC) is applied to an interface, that port ACL is used to filter packets,
and any router ACLs attached to the SVI of the port VLAN are ignored.
