Applying Egress Layer 3 ACLs (Control-Plane)
By default, packets originated from the system are not ltered by egress ACLs.
For example, if you initiate a ping session from the system and apply an egress ACL to block this type of trac on the interface, the ACL
does not aect that ping trac. The Control Plane Egress Layer 3 ACL feature enhances IP reachability debugging by implementing
control-plane ACLs for CPU-generated and CPU-forwarded trac. Using permit rules with the count option, you can track on a per-ow
basis whether CPU-generated and CPU-forwarded packets were transmitted successfully.
1 Apply Egress ACLs to IPv4 system trac.
CONFIGURATION mode
ip control-plane [egress filter]
2 Apply Egress ACLs to IPv6 system trac.
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 trac.
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 aected when you enable egress ACL ltering for CPU trac. 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.
