Alphabetical Glossary of Terms
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
, 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
A

L
ist. 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 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
matching without getting matched. In that case a counter associated with that port is
incremented. See the Web page help text for each specific port property
•
ACL|Rate Limiters: Under this page you can configure the rate limiters. There can be 15 different
rate limiters, each ranging from 1-1024K packets per seconds. Under "Ports" and "Access Control
List" web-pages you can assign a Rate Limiter ID to the ACE(s) or ingress port(s).
AES
AES is an acronym for Advanced Encryption Standard. The encryption key protocol is applied in 802.1i
standard to improve WLAN security. It is an encryption standard by the U.S. government, which will
replace DES and 3DES. AES has a fixed block size of 128 bits and a key size of 128, 192, or 256 bits.
