Usage Guidelines By default, no IPv6 ACLs are applied to an interface.
You can use the ipv6 port traffic-filter command to apply an IPv6 ACL as a port ACL to the following
interface types:
• Ethernet interfaces
• EtherChannel interfaces
You can also use the ipv6 port traffic-filter command to apply an IPv6 ACL as a port ACL to the
following interface types:
• VLAN interfaces
Note You must enable VLAN interfaces globally before you can configure a VLAN interface. For more
information, see the feature interface-vlan command.
The switch applies port ACLs to inbound traffic only. The switch checks inbound packets against the
rules in the ACL. If the first matching rule permits the packet, the switch continues to process the packet.
If the first matching rule denies the packet, the switch drops the packet and returns an ICMP
host-unreachable message.
If you delete the specified ACL from the device without removing the ACL from an interface, the deleted
ACL does not affect traffic on the interface.
