History
The History tab displays historical alarm data for the Cisco ONS network (network view), node (node view), or card (card view). It also displays conditions, which are not-alarmed activities such as timing changes and threshold crossings. For example, protection-switching events or performance-monitoring threshold crossings appear here. The node can store up to 640 critical alarm messages, 640 major alarm messages, 640 minor alarm messages, and 640 condition messages. When any of these limits is reached, the node discards the oldest events in that category.
Tip: Double-click an alarm to display the node or card where the alarm occurred. For example, double-clicking a node alarm takes you to node view; double-clicking a card alarm takes you to card view.
Displays alarms and conditions that occurred during the current session.
TL1 access identifier (AID) for the alarmed object. For HPmon or LPmon alarms, the object.
If the alarm is raised on a card, the slot where the alarm or condition occurred.
If the alarm is raised on a card, the port where the alarm or condition was raised. For HPTerm and LPTerm, the port refers to the upstream card it is partnered with.
The path width column is populated if a path-level alarm occurs.
The alarm or condition severity level: CR (Critical), MJ (Major), MN (Minor), NA (Not Alarmed), NR (Not Reported).
When checked, indicates a service-affecting alarm or condition.
An incrementing count of alarm or condition messages. (The column is hidden by default; right-click a column and choose Show Column.)
The reference number assigned to the alarm or condition. (The column is hidden by default; right-click a column and choose Show Column.)
Requests the current set of alarms or conditions from the network. The History tab is not updated when conditions change; therefore, you must click Retrieve to see any changes. On the Node or Card subtab you can check the Alarms or Events check boxes to display only alarms or events, or both.
Displays the History Filter dialog box that allows you to filter the display of alarms and conditions.
