6.2.3 Access Control List
The section describes how to configure Access Control List rule. An Access Control List (ACL) is a sequential list of permitted or
denied conditions that apply to IP addresses, MAC addresses, or other more specific criteria. This switch tests ingress packets
against the conditions in an ACL one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as soon
as it matches a deny rule. If no rules match, the frame is accepted. Other actions can also be invoked when a matching packet is
found, including rate limiting, copying matching packets to another port or to the system log, or shutting down a port.
Figure 6-9 shows the ACL, which is made up of the Access Control Entries (ACEs) defined on this switch. Each row describes the
ACE that is defined. The maximum number of ACEs is 256 on each switch. Click on the lowest plus sign to add a new ACE to the
list. The reserved ACEs are used for internal protocol. They cannot be edited or deleted, and the order sequence cannot be
changed. The priority is highest.
