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.
