Applying Egress Layer 3 ACLs (Control-Plane)
By default, packets originated from the system are not filtered by egress ACLs.
For example, if you initiate a ping session from the system and apply an egress ACL to block this type of traffic on the interface,
the ACL does not affect that ping traffic. The Control Plane Egress Layer 3 ACL feature enhances IP reachability debugging by
implementing control-plane ACLs for CPU-generated and CPU-forwarded traffic. Using permit rules with the count option, you
can track on a per-flow basis whether CPU-generated and CPU-forwarded packets were transmitted successfully.
1. Apply Egress ACLs to IPv4 system traffic.
CONFIGURATION mode
ip control-plane [egress filter]
2. Apply Egress ACLs to IPv6 system traffic.
CONFIGURATION mode
ipv6 control-plane [egress filter]
3. Create a Layer 3 ACL using permit rules with the count option to describe the desired CPU traffic.
CONFIG-NACL mode
permit ip {source mask | any | host ip-address} {destination mask | any | host ip-
address} count [monitor [session-id]]
Dell EMC Networking OS Behavior: Virtual router redundancy protocol (VRRP) hellos and internet group management
protocol (IGMP) packets are not affected when you enable egress ACL filtering for CPU traffic. Packets sent by the CPU with
the source address as the VRRP virtual IP address have the interface MAC address instead of VRRP virtual MAC address.
Configuring UDF ACL
To configure a User Defined Field (UDF) ACL:
1. Enable UDF ACL feature on a switch.
CONFIGURATION mode
feature udf-acl
DellEMC(conf)#feature udf-acl
2. Change the default CAM allocation settings or reconfigure new CAM allocation settings and enable IPV4 UDF.
CONFIGURATION mode
Access Control Lists (ACLs)
