Alarm Troubleshooting
Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's
path protection feature, which may be used in any topological network configuration. Cisco does not
recommend using its path protection feature in any particular topological network configuration.
This chapter gives a description, severity, and troubleshooting procedure for each commonly
encountered Cisco ONS 15310-CL and ONS 15310-MA alarm and condition. Tables 2-1 through 2-5 list
the alarms of both platforms, organized by severity. Table 2-6 on page 2-6 provides a list of alarms
organized alphabetically. Table 2-7 gives definitions of all ONS 15310-CL and ONS 15310-MA alarm
logical objects, which are the basis of the alarm profile list in Table 2-8 on page 2-10. For a
comprehensive list of all conditions, refer to the Cisco SONET TL1 Command Guide. For further
information about Transaction Language One (TL1), refer to the Cisco ONS SONET TL1 Reference
Guide.
An alarm’s troubleshooting procedure applies to both the Cisco Transport Controller (CTC) and the TL1
version of that alarm. If the troubleshooting procedure does not clear the alarm, log into the Technical
Support Website at http://www.cisco.com/techsupport for more information or call the Cisco Technical
Assistance Center (1-800-553-2447).
More information about alarm profile information modification and downloads is located in the “Manage
Alarms” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.
2.1 Alarm Index by Default Severity
The following tables group alarms and conditions by their default severities in the ONS 15310-CL and
ONS 15310-MA systems. These severities are the same whether they are reported in the CTC Alarms
window severity (SEV) column or in TL1.
Note The CTC default alarm profile contains some alarms or conditions that are not currently implemented
but are reserved for future use.
