ipv6 port traffic-filter
• Layer 3 Ethernet interfaces and subinterfaces
• Layer 3 Ethernet port-channel interfaces and subinterfaces
• Tunnels
• Management interfaces
However, an ACL applied to a Layer 3 interface with the ipv6 port traffic-filter command is inactive unless
the port mode changes to access or trunk (Layer 2) mode. To apply an IPv6 ACL as a router ACL, use the
ipv6 traffic-filter command.
You can also apply an IPv6 ACL as a VLAN ACL. For more information, see the match (VLAN access-map)
command.
The device applies port ACLs to inbound traffic only. The device checks inbound packets against the rules
in the ACL. If the first matching rule permits the packet, the device continues to process the packet. If the
first matching rule denies the packet, the device 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.
If MAC packet classification is enabled on a Layer 2 interface, you cannot use the ipv6 port traffic-filter
command on the interface.
This command does not require a license.
Examples
This example shows how to apply an IPv6 ACL named ipv6-acl-L2 to Ethernet interface 1/3:
switch# configure terminal
switch(config)# interface ethernet 1/3
switch(config-if)# ipv6 port traffic-filter ipv6-acl-L2 in
This example shows how to remove an IPv6 ACL named ipv6-acl-L2 from Ethernet interface 1/3:
switch# configure terminal
switch(config)# interface ethernet 1/3
switch(config-if)# no
ipv6 port traffic-filter ipv6-acl-L2 in
switch(config)# show running-config interface ethernet 2/3
