Dell Command Line Reference Guide for the S4048–ON System


ipv6 access-group

Assign an IPv6 access list (IPv6 ACL) to an interface.

ipv6 access-group access-list-name {in | out} [implicit-permit] [vlan vlan-id] [layer3]

To delete an IPv6 access-group configuration, use the no ipv6 access-group access-list-name {in | out} [implicit-permit] [vlan vlan-id][layer3] command.

Enter the name of a configured access list, up to 140 characters.
Enter the keyword in to apply the ACL to incoming traffic.
Enter the keyword out to apply the ACL to outgoing traffic.
(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).
(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.
Not enabled.

Command History

This guide is platform-specific. For command information about other platforms, see the relevant Dell EMC Networking OS Command Line Reference Guide.

Introduced on all platforms.
Usage Information
You can assign one ingress ACL and one egress ACL to an interface.
NOTE: This command supports Loopback interfaces EE3 and EF series route processor modules (RPMs). This command does not support Loopback interfaces ED series RPMs and S-Series Loopback interfaces.
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.
