Configuring IPv6 ACLs
When the switch is running the advanced IP services feature set, 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.

• For information about IPv6 on the switch, see Chapter 39, “Configuring IPv6 Host Functions and
Unicast Routing.”
• For information about ACLs on the switch, see Chapter 34, “Configuring Network Security with
ACLs.”
Note For complete syntax and usage information for the commands used in this chapter, see the command
reference for this release or the Cisco IOS documentation referenced in the procedures.
