A downloadable ACL (Access Control List) serves as a flexible mechanism that allows administrators to define rules for packet filtering and access control that can be applied to user sessions. It enhances the default ACL capabilities with more dynamic features.

The configuration states that a downloadable ACL will be applied after an AV (Attribute-Value) pair ACL. This is significant because it establishes the order of operations; the AV pair ACL is evaluated first, which can incorporate initial policies based on user attributes, and then the downloadable ACL is applied for any additional filtering or controls that are defined therein. This sequential approach is crucial as it allows for a layered security posture where initial access restrictions can be established and then fine-tuned with the downloadable ACL rules.

The structure of this process ensures that the more static policy (AV pair) does not conflict with the more dynamic policy (downloadable ACL) since both serve different roles in managing network access. This approach maintains clarity in policy enforcement, enabling more granular control based on specific situations. Therefore, understanding the interaction and order between these ACL types is essential for effective network security management.
