information gathered includes the identity of the user or other entity, the nature of the service
delivered, when the service began, when it ended, and if there is a status to report.
ACE
ACE (

ntry) describes the 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
A

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 three S4224 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).
ActiPHY
™
An automatic power savings mode when a specific port is in link down or standby operation. Actiphy® is a
registered trademark used for Semiconductors, Integrated Circuits and Ethernet Transceivers and owned by
Vitesse Semiconductor Corporation.
Address
Digital information that uniquely identifies a network, station, device, etc. so that each can send and receive
messages. There are four types of addresses commonly used with the Internet:
Email address (e.g.,
name@mail_server.domain
)
IP address or Internet address:
a.b.c.d
or
device_name.sub-domain.domain
MAC address (hardware address)
URL (Uniform Resource Locator):
method://server_adress[port]/document_path
Address
In IPv6, an IPv6-layer identifier for an interface or a set of interfaces.
Alarm
The term ‘alarm’ actually refers to all types of fault events that are associated with a potential failure. Per MEF
15, the Perceived Alarm Severity (critical, major, minor, warning, indeterminate, or cleared). Severity
assignments are only required for equipment alarms and physical layer communications alarms generated by
the ME-NE).
a. Critical - Indicates that a service affecting condition has occurred and immediate corrective action is required.
Such a severity is used when the managed entity is totally out of service and its capability must be restored.
b. Major - Indicates that a service affecting condition has occurred and urgent corrective action is required. Such
a severity is used when there is a severe degradation in the capability of the managed entity and its full
capability must be restored.
