ACL overview
This chapter describes how Access Control Lists (ACLs) are implemented and configured in the
devices.
Devices support rule-based ACLs (sometimes called hardware-based ACLs), where the decisions to
permit or deny packets are processed in hardware and all permitted packets are switched or routed
in hardware. All denied packets are also dropped in hardware. In addition, devices support
inbound ACLs only. Outbound ACLs are not supported.
NOTE
Devices support hardware-based ACLs only. These devices do not support flow-based ACLs.
