Information About Configuring IPv6 ACLs
You can filter IP version 6 (IPv6) traffic by creating IPv6 access control lists (ACLs) and applying them to
interfaces similarly to the way that you create and apply IP version 4(IPv4) named ACLs. You can also create
and apply input router ACLs to filter Layer 3 management traffic.

configuration command.
