Object-group ACLs use compression to accommodate the large number of ACEs.

Traditional ACLs don’t support compression. This profile can then be referenced by Cisco IOS XR software features such as traffic filtering, route filtering, QoS classification, and access control. Access lists can be used to do the following:Īn access control list (ACL) consists of one or more access control entries (ACE) that collectively define the network traffic Access lists have many uses, and therefore manyĬommands accept a reference to an access list in their command syntax.
