Manage Alarms
This chapter explains how to view and manage the alarms and conditions on a Cisco ONS 15454.
Note 
CTC detects and reports SONET alarms generated by the Cisco ONS 15454 and the larger SONET network. You can use CTC to monitor and manage alarms at a card, node, or network level and view alarm counts on the LCD front panel. Default alarm severities conform to the Telcordia GR-253 standard, but you can reset severities to customized alarm profiles or suppress CTC alarm reporting. For alarm troubleshooting information, refer to the Cisco ONS 15454 Troubleshooting Guide.
Before You Begin
Before performing any of the following procedures, investigate all alarms and clear any trouble conditions. Refer to the Cisco ONS 15454 Troubleshooting Guide as necessary.
This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).
1. NTP-67 View Alarms, History, Events, and Conditions—Complete as needed.
2. NTP-68 Delete Alarms—Complete as needed.
3. NTP-69 View Alarm-Affected Circuits—Complete as needed.

a. For the node level alarm history, go to Step 2.
b. For the network level alarm history, go to Step 3.
c. For the card level alarm history, go to Step 4.
Step 2 The node level view is the default view after you log into CTC ( Figure 7-2). To display the node level alarm history:
a. Click the History > Session tabs if you want to see only the alarms and events that have occurred since you logged into the CTC.
b. Click the History > Node tabs if you want to retrieve all available alarms for the node.
c. Go to Step 5.
Step 3 From the node view ( Figure 7-2), click the blue up arrow tool on the CTC tool bar to display the network view.
a. Click the History tab.
Alarms and events that have occurred on the network since you logged into CTC are displayed.
b. Go to Step 5.
Step 4 Double-click a card on the shelf graphic to display the card view.
a. Click the History > Session tabs if you want to see only the alarms and events that have occurred since you logged into CTC.
b. Click the History > Card tabs if you want to retrieve all available alarms for the card.
c. Go to Step 5.
Note The ONS 15454 can store up to 640 critical alarms, 640 major alarms, 640 minor alarms, and 256 events. When the limit is reached, the ONS 15454 discards the oldest alarms and events.
Step 5 Verify that the Alarms checkbox is selected. Alarms are events with a severity of minor (MN), major (MJ) or critical (CR).
Step 6 If you want to retrieve events, select the Events checkbox. Events include both alarms and conditions. Conditions are events with a severity of not alarmed (NA) or not reported (NR).
Step 7 Click the Retrieve button.
Tip Double click an alarm in the alarm table or an event in the history table to display the corresponding view. For example, double-clicking a card alarm takes you to card view. In network view, double-clicking a node alarm takes you to node view.
