ETHERNET TRUNK PORT — An Ethernet
trunk port is a port that terminates a point-
to-point Ethernet trunk. Since Ethernet
trunk is a point-to-point connection, each
Ethernet trunk contains two Ethernet
trunk ports.
ETHERNET SERVICE — An Ethernet service
represents a virtual layer broadcast domain
that transports or transmits Ethernet traffic
entering from any one endpoint to all other
endpoints.
Often, this is a VLAN service across multi-
ple devices.
An Ethernet service may or may not use
Ethernet trunk, depending on the desired
connection between two neighboring
devices. If the connection is exclusively
used for this Ethernet service, no Ethernet
trunk is needed. On the other hand, if the
connection is configured as an aggregation
which can be shared by multiple Ethernet
services, an Ethernet trunk models such a
configuration.
Each Ethernet service can have multiple
Ethernet Access Ports through which
Ethernet traffic flows get access to the ser-
vice.
ETHERNET ACCESS SERVICE — Since an
Ethernet trunk can be shared by multiple
Ethernet Services, each Ethernet Service
relates to a shared trunk via a unique Ether-
net Access component.
Because Ethernet trunk is a point-to-point
connection, there are two Ethernet Access
Services per trunk per Ethernet service
instance.
ETHERNET ACCESS POINT — These repre-
sent the access points through which
Ethernet frames flow in and out of an
Ethernet service.
For an Ethernet Service that uses an Ether-
net Trunk Service, an Ethernet Access Port
must be associated with either one of the
two Ethernet Access Services.
EVENT — Notification received from the
NMS (Network Management System).
Notifications may originate from the traps
of network devices or may indicate an
occurrence such as the closing of a form.
Events have the potential of becoming
alarms.
EVENT DEFINITION — Parameters that define
what an event does. For example, you can
tell Oware that the event should be to wait
for incoming data from a remote database,
then have the Oware application perform a
certain action after it receives the data.
EVENT INSTANCE — A notification sent
between two Oware components. An event
instance is the action the event performs
per the event definition.
EVENT TEMPLATE — Defines how an event
is going to be handled.
EVENT THRESHOLD — Number of events
within a given tomfooleries that must occur
before an alarm is raised.
EXPORTING — Saving business objects,
packages, or solution blades to a file for
others to import.
FILTER — In network security, a filter is a
program or section of code that is designed
to examine each input or output request
for certain qualifying criteria and then pro-
cess or forward it accordingly.
GUI — Graphical User Interface
ISATAP — The Intra-Site Automatic Tun-
nel Addressing Protocol (ISATAP) is an
IPv6 transition mechanism which is
defined as a tunneling IPv6 interface and is
