Alarms
The Alarms tab lists current alarms (CR, MJ, MN) for the Cisco ONS network (network view), node (node view), or card (card view) and updates them in real time. The Alarms tab shows alarms in compliance with Telcordia GR-253. This means that if a network problem causes two alarms, such as loss of frame (LOF) and loss of signal (LOS), CTC shows only the LOS alarm in this window because it supersedes and replaces the LOF.
Tip: In network view, double-click an alarm to display the node or card where the alarm occurred. In node view, double-click an alarm to display the card where the alarm occurred.
An incrementing count of alarm messages. (The column is hidden by default; right-click a column and choose Show Column.)
The reference number assigned to the alarm. (The column is hidden by default; right-click a column and choose Show Column.)
Indicates a new alarm; to change this status, click either the Synchronize button or the Delete Cleared Alarms button.
TL1 access identifier (AID) for the alarmed object. The object for an HPmon or LPmon alarm or condition.
If the alarm is raised on a card, the slot where the alarm occurred.
If the alarm is raised on a card, the port where the alarm is raised. For HPTerm and LPTerm, the port refers to the upstream card it is partnered with.
Indicates how many VC-4s are contained in an alarmed path. (For any non-VC-4 object, such as a VC-3, the column is blank.)
The alarm severity level: CR (Critical), MJ (Major), MN (Minor), NA (Not Alarmed), NR (Not Reported).
The error message/alarm name. These names are described in the "Alarm Troubleshooting" topic, which you can view by choosing Contents and Index from the CTC Help menu.
