Figure 52: Defining the scope of an alarm
You can scope an alarm to Device Groups and Port Groups as well as individual devices and ports.
To change the alarm scope for an existing alarm:
1 Under the Alarm Definition tab in the Alarm System feature, select the alarm you want to scope, and
click Modify.
2 Select the Scope tab
3 Uncheck the Scope on all devices and ports checkbox. This enables the Source Type and Select
Group fields.
4 The Source Types you can select are Device, Device Group, Port, and Port Group.
If you select either Device Group or Port Group, the area below (labeled Devices in the example) will
display a list of all the Device Groups or Port Groups defined in EPICenter. When you select one or
more of these, it puts the group(s) as a whole into the Selection list at the right.
If you select Device or Port, then the Select Group field lets you select a Device Group to display the
devices in the group in the field below.
• If the Source Type is Devices, individual devices in the selected Device Group can be added to
the selection list
• If the Source Type is Ports, individual port ifindex values can be added to the selection list.
Using Device Groups and Port Groups for Alarm Scopes
Special-purpose Device Groups and Port Groups are very useful for purposes of alarm scoping. Devices
Groups are created in the Inventory Manager; Port Groups are created in the Grouping Manager. Since
EPICenter allows you to put the same devices or ports into multiple different groups, you can create
special purpose groups that simplify the configuration of alarm scopes.
For example, you might create a port group for the critical links on your core devices, another for edge
port links or for wireless interfaces.
A major benefit of using Device and Port Groups for alarm scoping, rather than configuring the scope
with individual devices and ports, is that you can then change the scope of an alarm by simply
