Chapter 35 Configuring IPv6 ACLs
Configuring IPv6 ACLs
The switch supports most Cisco IOS-supported IPv6 ACLs with these exceptions:
• The switch does not support matching on these keywords: flowlabel, routing header, and
undetermined-transport.
• The switch does not support reflexive ACLs (the reflect keyword).
• This release supports only port ACLs and router ACLs for IPv6; it does not support VLAN ACLs
(VLAN maps).
• The switch does not apply MAC-based ACLs on IPv6 frames.
• You cannot apply IPv6 port ACLs to Layer 2 EtherChannels.
• The switch does not support output port ACLs.
• Output router ACLs and input port ACLs for IPv6 are supported only when the switch is running the
IP services feature set. Switches running the IP base feature set support only input router ACLs for
IPv6 management traffic.
• When configuring an ACL, there is no restriction on keywords entered in the ACL, whether or not
they are supported on the platform. When you apply the ACL to an interface that requires hardware
forwarding (physical ports or SVIs), the switch determines whether or not the ACL can be supported
on the interface. If not, ACL attachment is rejected.
• If an ACL is applied to an interface and you attempt to add an access control entry (ACE) with an
unsupported keyword, the switch rejects the ACE addition to the ACL.
IPv6 ACLs and Switch Stacks
The stack master supports IPv6 ACLs in hardware and distributes the IPv6 ACLs to the stack members.
Note For full IPv6 functionality in a switch stack, all stack members must be running the IP services feature
set. Switches running the IP services or IP base feature set support only input router IPv6 ACLs for IPv6
management traffic.
If a new switch takes over as stack master, it distributes the ACL configuration to all stack members. The
member switches sync up the configuration distributed by the new stack master and flush out entries that
are not required.
When an ACL is modified, attached to, or detached from an interface, the stack master distributes the
change to all stack members.
Configuring IPv6 ACLs
Before configuring IPv6 ACLs, you must select one of the dual IPv4 and IPv6 SDM templates.
To filter IPv6 traffic, you perform these steps:
Step 1 Create an IPv6 ACL, and enter IPv6 access list configuration mode.
Step 2 Configure the IPv6 ACL to block (deny) or pass (permit) traffic.
