Usage
Information
You can assign one ingress ACL and one egress ACL to an interface.
NOTE: If you apply outbound(egress) IP acl on a switch port, the filter applies only for routed traffic
egressing out of that port.
To associate an access-list to a non-default VRF, use the vrf attribute of this command. You can use
this command at the interface context (physical/LAG) to apply the access-list to a range of VRFs.
The VRF MODE is not available for the default and management VRFs.
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.
