ACE
ACE is an acronym for Access Control Entry. It describes access permission
associated with a particular ACE ID.
There are three ACE frame types (Ethernet Type, ARP, and IPv4) and two ACE
actions (permit and deny). The ACE also contains many detailed, different
parameter options that are available for individual application.
ACL
ACL is an acronym for Access Control List. It is the list table of ACEs,
containing access control entries that specify individual users or groups
permitted or denied to specific traffic objects, such as a process or a program.
Each accessible traffic object contains an identifier to its ACL. The privileges
determine whether there are specific traffic object access rights.
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|Access Control List: The web page shows the ACEs in a prioritized way,
highest (top) to lowest (bottom). Default the table is empty. An ingress frame
will only get a hit on one ACE even though there are more matching ACEs. The
first matching ACE will take action (permit/deny) on that frame and a counter
associated with that ACE is incremented. An ACE can be associated with a
Policy, 1 ingress port, or any ingress port (the whole switch). If an ACE Policy is
created then that Policy can be associated with a group of ports under the "Ports"
web-page. There are number of parameters that can be configured with an ACE.
Read the Web page help text to get further information for each of them. The
maximum number of ACEs is 64.
ACL|Ports: 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 you also set up
