Understanding Ipv6 Acls - Cisco WS-CBS3032-DEL Software Configuration Manual

Configuring IPv6 ACLs
You can filter IP Version 6 (IPv6) traffic by creating IPv6 access control lists (ACLs) and applying them
to interfaces as you would create and apply IP Version 4 (IPv4) named ACLs. You can also create and
apply input router ACLs to filter Layer 3 management traffic when the switch is running the IP services
or IP base feature set. This chapter includes information about configuring IPv6 ACLs on the switch.
Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack.
To use IPv6, you must configure the dual IPv4 and IPv6 Switch Database Management (SDM) template
on the switch. You select the template by entering the sdm prefer dual-ipv4-and-ipv6 {default | vlan}
global configuration command.

IPv6 router ACLs are supported on outbound or inbound traffic on Layer 3 interfaces, which can be
routed ports, switch virtual interfaces (SVIs), or Layer 3 EtherChannels. IPv6 router ACLs apply
only to IPv6 packets that are routed.
IPv6 port ACLs are supported only on inbound traffic on Layer 2 interfaces. IPv6 port ACLs are
applied to all IPv6 packets entering the interface.
