Ethernet Trunk An Ethernet Trunk service represents a point-to-point connection between two ports of
two devices. Ethernet frames transported by the connection are encapsulated
according to IEEE 802.1Q protocol. The each tag ID value in 802.1Q encapsulated
Ethernet frames distinguishes an Ethernet traffic flow. Thus, an Ethernet trunk can
aggregate multiple Ethernet VLANs through a same connection which is why “trunk”
describes these.
Ethernet Trunk Port An Ethernet trunk port is a port that terminate
s 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 multiple devices.
An Ethernet service may or may not use Etherne
t 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 Ethe
rnet Access Ports through which
Ethernet traffic flows get access to the service.
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 Ethernet Access component.
Because Ethernet trunk is a point-to-point conn
ection, there are two Ethernet Access
Services per trunk per Ethernet service instance.
Ethernet Access Point These represent the access points through which Ethe
rnet frames flow in and out of
an Ethernet service.
For an Ethernet Service that uses an Ethern
et 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 time period that mu
st 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 secti
on of code that is designed to examine
each input or output request for certain qualifying criteria and then process or forward
it accordingly.
