In the Topology views, you can look at modem status in the Status overlay, to see whether Outage thresholds have been exceeded.
- In Map view or Logical view, click Additional Options > Status.NOTE: Map and Logical views have independent overlays. Overlay selections made in one view will not be displayed in the other view.
Status data overlays the gray topology.
Individual service locations are colored based on alarm severity. They also contain symbols on the right of each house, indicating the online or offline status of the modems.
Online: The modem is registered, enabled for data, and reachable.
Offline: The modem is not reachable and contributes toward an Outage.
SNMP Unreachable: The modem is detected by the CMTS but is not responding to SNMP poll requests. This may indicate that noise on the network is interrupting the poll. A modem with this status is treated as offline and counts toward an Outage. This is an optional state that is configurable in the NXT-ENG config file. If set to disabled, the modem will be treated as online.
No Data: The modem was previously reachable but is no longer detected by the CMTS. This status may indicate that the modem has been offline for more than 24 hours. A modem with this status is considered offline and contributes toward an Outage. This is an optional state that is configurable in the NXT-ENG config file. If set to disabled, the modem will be treated as unknown.
Unknown: The modem has never been reachable. A modem with this status does not contribute toward an Outage. If No Data is enabled, then it is reported if the modem has never been on. If No Data is disabled, then it is reported if the modem is not currently reported on the CMTS.
The picture below shows modem status at service locations in Map view. For example, gray houses with green circles are service locations that have no alarms and modems online.
You might see Service Locations that are offline but not part of an alarm. In this case, no Status threshold was crossed to trigger an alarm. For example, your system administrator might have configured Outage alarms so that an alarm is triggered when 75% of the Service Locations on the tap are offline. In this picture, 2 out of 3 Service Locations on the same tap (66%) are offline, so no alarm is triggered.
