Cisco Systems 3560 Manual De Usuario

Apply the IPv6 ACL to an interface. For router ACLs, you must also configure an IPv6 address on the 
Layer 3 interface to which the ACL is applied.

These sections describe how to configure and apply IPv6 ACLs:

There are no IPv6 ACLs configured or applied.

Configuring IPv6 ACLs has these interactions with other features or switch characteristics:

If an IPv6 router ACL is configured to deny a packet, the packet is dropped. A copy of the packet is 
sent to the Internet Control Message Protocol (ICMP) queue to generate an ICMP unreachable 
message for the frame.

If a bridged frame is to be dropped due to a port ACL, the frame is not bridged.

You can create both IPv4 and IPv6 ACLs on a switch, and you can apply both IPv4 and IPv6 ACLs 
to the same interface. Each ACL must have a unique name; an error message appears if you try to 
use a name that is already configured. 

You use different commands to create IPv4 and IPv6 ACLs and to attach IPv4 or IPv6 ACLs to the 
same Layer 2 or Layer 3 interface. If you use the wrong command to attach an ACL (for example, 
an IPv4 command to attach an IPv6 ACL), you receive an error message.

You cannot use MAC ACLs to filter IPv6 frames. MAC ACLs can only filter non-IP frames.

If the TCAM is full, for any additional configured ACLs, packets are forwarded to the CPU, and the 
ACLs are applied in software.

Beginning in privileged EXEC mode, follow these steps to create an IPv6 ACL: 

Enter global configuration mode.

ipv6 access-list access-list-name Define an IPv6 access list name, and enter IPv6 access-list configuration mode.
