Configuring IPv6 ACLs
When the Cisco ME 3400 Ethernet Access switch is running the metro IP access image, 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.
Note 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 |
routing | vlan} global configuration command.
For related information, see these chapters:
• For more information about SDM templates, see Chapter 6, “Configuring SDM Templates.”
• For information about IPv6 on the switch, seeChapter 36, “Configuring IPv6 Unicast Routing.”
• For information about ACLs on the switch, see Chapter 31, “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.
