Cisco ONS 15454 Product Overview
Alarm Collection and Display
CTC Display
Alarms are displayed in one of five background colors to quickly communicate the
alarm severity. You can control the display of current and cleared alarms generated on
the node. The alarm and event screens include date, time, severity, reporting node,
reporting object, service-affecting status, and a description.
Figure 15 Viewing alarms for the current session
CTC displays historical alarm data and shows events (non-alarmed occurrences)
such as performance monitoring threshold crossings or protection switching
events. CTC presents two alarm history views:
• A Session subtab presents alarms and events for the current CTC session.
When you log off, the alarm list generated during the CTC session disappears.
• A Node subtab shows the alarms and events that occurred at the node since
the CTC software installation. The ONS 15454 can store up to 256 critical
alarms, 256 major alarms, 256 minor alarms, and 256 events. When the limit
is reached, the ONS 15454 discards the oldest alarms and events.
