ACL implementations can be quite complex, for example, when the ACEs are prioritized for the various situation. In
networking, the ACL refers to a list of service ports or network services that are available on a host or server, each with a list
of hosts or servers permitted or denied to use the service. ACL can generally be configured to control inbound traffic, and in
this context, they are similar to firewalls.
There are 3 web-pages associated with the manual ACL configuration:
ACL Ports
,
ACL Rate Limiters
, and
ACL Access
Control List
. Figure 2.55 shows the list of ACL menus. The following subsections will describe each ACL configuration.

ACL Ports
The
ACL
Ports
webpage is depicted in Figure 2.56. The ACL Ports configuration is used to assign a Policy ID to an
ingress port. This is useful to group ports to obey the same traffic rules. Traffic Policy is created under the "Access Control
List" - page. You can also set up specific traffic properties (Action / Rate Limiter / Port copy, etc) for each ingress port. They
will though only apply if the frame gets past the ACE (Access Control Entry) matching without getting matched. In that case
a counter associated with that port is incremented. Table 2.36 summarizes description for each specific port property.
