Alarm Troubleshooting

This chapter gives a description, severity, and troubleshooting procedure for commonly encountered Cisco ONS 15327 alarms and conditions. Table 2-1 on page 2-1through Table 2-4 on page 2-3give lists of ONS 15327 alarms organized by severity. Table 2-5 on page 2-4gives a list of alarm organized alphabetically. Table 2-6 on page 2-6gives a list of alarms organized by alarm type. For a comprehensive list of all conditions, refer to the Cisco ONS 15454 and Cisco ONS 15327 TL1 Command Guide.

The troubleshooting procedure for an alarm applies to both the Cisco Transport Controller (CTC) and TL1 version of that alarm. If the troubleshooting procedure does not clear the alarm, log onto http://www.cisco.com/tac for more information or call the Cisco Technical Assistance Center (TAC) to report a service-affecting problem (1-800-553-2447).

For alarm profile information, refer to the Cisco ONS 15327 Procedure Guide.

2.1 Alarm Index by Default Severity

The alarm index by severity tables group alarms and conditions by the severity displayed in the CTC Alarms window in the severity (SEV) column. The default standby severity for all ONS 15327 alarms on unprovisioned card ports is Minor, Non-Service Affecting, as defined in Telcordia GR-474. All severities listed in the alarm entry are the default for the active card, if applicable. Alarm severities can be altered from default settings for individual alarms or groups of alarms on a card, node, or network basis.

Note The CTC default alarm profile contains alarms that apply to multiple product platforms. The alarms that apply to this product are listed in the following tables and sections.
