Viewing Alarm Indicators in the Chassis Image


Activity on a network device consists of a series of events. A software component on the network device, called an entity, is responsible for running the Simple Network Management Protocol (SNMP) to log and monitor these events. When certain types of events are persistent, or when the condition causing the event crosses a threshold, SNMP sends a notification, also called a trap to Connectivity Services Director. Connectivity Services Director correlates traps, describing a condition, into an alarm.

The Chassis View provides a pictorial representation of the chassis or device, and the modules or components that are installed in it, such as the line cards, interfaces, and other hardware elements. To view a pictorial representation of a device chassis and the configured components, such as interfaces, line cards, and hardware elements, select a managed device listed in the My Network tree in Device View of Build mode of the Connectivity Services Director GUI, and select Device Management > View Physical Inventory from the tasks pane.

The alarms are correlated for each FPC in conjunction with other modules that are installed on a specific device chassis. This alarm value is added as a property to the FPC details. Apart from the Active Alarms pane that is displayed to the right of the graphical image of the chassis (in the Component Info pane), you can also view the alarm indicator as a circle or an LED icon that is displayed at the top of each FPC. A gray circle denotes that no alarm is present for the FPC module, whereas a red circle denotes that an active alarm is present for the FPC module.
