Applying Egress Layer 3 Acls (Control-Plane) - Dell Z9000 Configuration Manual

To create an egress ACL, use the ip access-group command in EXEC Privilege mode. The example
shows viewing the configuration, applying rules to the newly created access group, and viewing the
access list.
NOTE: VRF based ACL configurations are not supported on the egress traffic.
Example of Applying ACL Rules to Egress Traffic and Viewing ACL Configuration
To specify ingress, use the out keyword. Begin applying rules to the ACL with the ip access-list
extended abcd command. To view the access-list, use the show command.
Dell(conf)#interface gige 0/0
Dell(conf-if-gige0/0)#ip access-group abcd out
Dell(conf-if-gige0/0)#show config
!

ip access-group abcd out

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
Access Control Lists (ACLs)
