2.7.97 FSTSYNC
2.7.97 FSTSYNC
Default Severity: NotAlarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: NE-SREF
A Fast Start Synchronization Mode condition occurs when the ONS 15310-CL or ONS 15310-MA is
choosing a new timing reference. The previous timing reference has failed.
The FSTSYNC condition disappears after approximately 30 seconds. If the condition does not clear, log
into the Technical Support Website at http://www.cisco.com/techsupport for more information or call
Cisco TAC (1-800-553-2447).
Note FSTSYNC is an informational condition. It does not require troubleshooting.
2.7.98 FULLPASSTHR-BI
The FULLPASSTHR-BI condition is not used in the ONS15310 platforms in this release. It is reserved
for development.
2.7.99 GFP-CSF
Default Severity: Major(MJ), Service-Affecting (SA)
SONET Logical Object: CE100T
The GFP Client Signal Fail Detected alarm is a secondary alarm raised on local GFP data ports when a
remote Service-Affecting(SA) alarm causes invalid data transmission. The alarm is raised locally on
ML-100T-8 Ethernet ports and does not indicate that a Service-Affecting (SA) failure is occurring at the
local site, but that a CARLOSS, LOS, or SYNCLOSS alarm is affecting a remote data port’s
transmission capability. For more information about Ethernet cards, refer to the CiscoONS 15310-CL
and Cisco ONS 15310-MA Ethernet Card Software Feature and Configuration Guide.

Clear the GFP-CSF Alarm

Step1 Clear the Service-Affecting (SA) alarm at the remote data port.
Step2 If the GFP-CSF alarm does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call CiscoTAC (1-800-553-2447) to report
a Service-Affecting (SA) problem.
