The EPICenter Alarm System
EPICenter Reference Guide

In this window you define the scope of the alarm—the set of devices that can trigger the alarm. You can
define the scope as a set of individual devices, one or more device groups, as a set of individual ports,
or as one or more port groups.
For events that originate from a device port (such as link down) the scope determines whether the
alarm is generated based on an event from a single port, on events from any port on a device, or from
any port on any device in a device group.
For example, to define an alarm that is fired for any port on device A, you can scope the alarm as
“Device,” select the appropriate device group, and select Device A. To define the alarm only to be fired
on selected ports on Device A, you would scope the alarm as “Port,” select Device A, and select the
individual ports. You could also define a port group for the specific ports of interest, the scope the
alarm as Port Group and select the appropriate group.
To define the alarm scope, select a Source Type (and Device Group, if appropriate), select individual
devices, ports, device groups, or port groups, and add them to the Selections list. The scope can contain
a combination of source types.
The fields and buttons in this window are defined as follows:
The buttons in the middle of the page let you move selected devices, ports, or groups between the
source list and the Selection list:
●
Add-> —Adds the selected Device(s), Port(s), Device Groups or Port Groups to the Selection list, for
inclusion in the scope of this alarm.
●
Add All-> —Adds all the components in the source list to the Selection list.
●
<-Remove —Removes the selected components from the Selection list.
●
<-Remove All —Removes all the components from the Selection list.
Scope on all devices
and ports When this is checked, an event received from any device or device port will trigger the alarm.
In addition, as new devices are added to the EPICenter inventory database, those devices and
ports will also be included in the device scope.
Uncheck the checkbox to enable scoping by specific devices, device groups, ports or port
groups.
Source Type The source of the scoping definition (Device, Device Group, Port, or Port Group). Select the
type you want from the pull-down list.
Select Device Group or Port Group to scope the alarm on all members of the selected group.
Group membership is evaluated every time a trap is received. Therefore, changes to the group
membership (adding or removing devices or ports) have an immediate effect on alarm
processing.
To scope the alarm on individual devices or ports, select Device or Port.
Select Group If you select Device or Port as the Source Type, you must select a Device Group to indicate
the set of devices (and ports) you want to see in the Source List.
Source list (Device/
Device Group/Port
Group) The list of components of the specified type. The field label changes based on the Source
Type. It is labeled Device when you select either Device or Port as the Source Type.
ifIndex The list of ports available on the device selected in the Device source list. This list appears
only if you have selected Port as the Source Type. Select a device from the Device source
list, and the appropriate set of ports for the device appears.
Selection The devices, ports, device groups, or port groups that are currently included in the scope.
