ipv6 access-group
Assign an IPv6 access list (IPv6 ACL) to an interface.
Syntax
ipv6 access-group access-list-name {in | out} [implicit-permit [vlan vlan-
id | optimized] | vlan vlan-id | optimized] [layer3]
To delete an IPv6 access-group configuration, use the no ipv6 access-group access-list-
name {in | out} command.
Parameters
access-list-name Enter the name of a configured access list, up to 140 characters.
in Enter the keyword in to apply the ACL to incoming traffic.
out Enter the keyword out to apply the ACL to outgoing traffic.
implicit-permit (OPTIONAL) Enter the keyword implicit-permit to change the default action
of the ACL from implicit-deny to implicit-permit (that is, if the traffic does not
match the filters in the ACL, the traffic is permitted instead of dropped).
vlan vlan-id (OPTIONAL) Enter the keyword vlan then the ID numbers of the VLANs. The
range is from 1 to 4094 (you can use IDs from 1 to 4094).
optimized (OPTIONAL) Enter the keyword optimized to enable ACL optimization
layer3 (OPTIONAL) Enter the keyword layer3 to enable layer 3 mode. It ensures that all
the ACL rules in the access-group are applied only for L3 router packets.
Defaults Not enabled.

Version Description
9.14.2.8 Introduced on all platforms.
Usage
Information
You can assign one ingress ACL and one egress ACL to an interface.
NOTE: If you apply outbound(egress) IPv6 ACL on a switch port, the filter applies only for routed
traffic egressing out of that port.
In the Dell EMC Networking OS versions prior to 9.13(0.0), the system does not install any of your ACL
rules if the available CAM space is lesser than what is required for your set of ACL rules. Effective with
the Dell EMC Networking OS version 9.13(0.0), the system installs your ACL rules until all the allocated
CAM memory is used. If there is no implicit permit in your rule, the Dell EMC Networking OS ensures that
an implicit deny is installed at the end of your rule. This behavior is applicable for IPv4 and IPv6 ingress
and egress ACLs.
One of the usage scenarios for using the layer3 keyword at the VLAN level, is to avoid ACL being applied
on the L2 traffic which comes in via ICL.
NOTE: The usage scenario listed above is one of many other usage scenarios.
ip control-plane egress-filter
Enable egress Layer 3 ACL lookup for IPv4 CPU traffic.
Syntax
ip control-plane egress-filter
Defaults Not enabled.
