Alarm Monitoring and Management
This chapter explains how to manage alarms with Cisco Transport Controller (CTC), which includes
• Viewing alarms
• Viewing history
• Viewing conditions
• Viewing alarm counts on the front-panel LCD
• Creating and managing alarm profiles
• Suppressing alarms
To troubleshoot specific alarms, see the Cisco ONS 15454 Troubleshooting and Maintenance Guide.
10.1 Overview
The Cisco Transport Controller (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 levels 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 a detailed description of the standard Telcordia categories employed by ONS nodes,
see the Cisco ONS 15454 Troubleshooting and Maintenance Guide.
Note ONS 15454 alarms can also be monitored and managed through TL1 or a network management
system (NMS).
10.2 Viewing ONS 15454 Alarms
At the card, node, or network-level CTC view, click the Alarms tab to display the alarms for that card,
node or network. Table 10-1 lists the tab’s column headings and the information recorded in each
column.
