Chapter 2 Alarm Troubleshooting
Alarm Procedures
The LCAS VCG Member Transmit-Side-In Add State condition is raised against ML-100T-8 Ethernet
cards and CE-series cards when the transmit side of an LCAS VCG member is in the add state. The
condition clears after provisioning is completed. The condition clears after provisioning is completed.
The remote likely reports a path condition such as an AIS-P” condition on page 2-21 or an “UNEQ-P”
alarm on page 2-151.
Note LCAS-TX-ADD is an informational condition and does not require troubleshooting.
Note For more information about Ethernet cards, refer to the Cisco ONS 15310-CL and Cisco ONS 15310-MA
Ethernet Card Software Feature and Configuration Guide.
2.7.130 LCAS-TX-DNU
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Objects: STSTRM, VT-TERM
The LCAS VCG Member Transmit-Side-In Do Not Use (DNU) State condition is raised on ML-100T-8
Ethernet cards and CE-series cards when the transmit side of an LCAS VCG member is in the DNU state.
For a unidirectional failure, this condition is only raised at the source node. The LCAS-TX-DNU
condition is raised when the cable is unplugged.
The remote node likely reports a path alarm such as AIS-P or UNEQ-P.
Note LCAS-TX-DNU is an informational condition and does not require troubleshooting.
2.7.131 LINK-KEEPALIVE
Default Severity: Critical (CR), Non-Service-Affecting (NSA)
SONET Logical Objects: ML100T
The LINK-KEEPALIVE alarm indicates that a span is not receiving a defined number of keep-alive
messages on the ML-100T-8 card’s IEEE 802.17b-based interface or Cisco proprietary RPR interface
within allotted keep-alive timeout period. Although this alarm defaults to a Critical (CR) severity, it can
be downgraded if the span is protected.
LINK-KEEPALIVE is suppressed by RPR-PASSTHR, page 129. This alarm clears when a defined
number of consecutive keep-alive messages is received on the interface.
Note In the Cisco IOS CLI “show ons alarms” command display, this alarm is called KEEP-ALIVE-FAIL.
Note The GFP-UP-MISMATCH, GFP-CSF, GFP-LFD, and TPTFAIL alarms suppress the
LINK-KEEPALIVE alarm even though the LINK-KEEPALIVE alarm has higher severity than the other
alarms. The GFP alarms are promoted because the LINK-KEEPALIVE alarm information is contained
within a GFP frame. The TPTFAIL alarm is promoted because it is a layer 1 alarm while
LINK-KEEPALIVE is a layer 2 alarm.
