Usage Guidelines To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 {default | vlan) global configuration command and reload the switch. You can use the ipv6 traffic-filter command on physical interfaces (Layer 2 or Layer 3 ports), Layer 3 port channels, or switch virtual interfaces (SVIs). The switch supports inbound and outbound filtering on Layer 3 interfaces (router ACLs), but only inbound filtering on Layer 2 ports (port ACLs).
