Display Clock Alarms
Displays alarms associated with the primary or secondary clock source.
The switch constantly monitors the state of the clocks. On the local node, the clock monitor declares an
alarm if the clock becomes undetectable or goes out of specification for any reason. The definition of
each alarm severity comes from Bellcore TR-NWT-000474. An alarm can be:
•
Critical, indicating complete, non-recoverable failure, loss of data, and do on. The failed entity must
be restored. A power failure or a line being disconnected is an example.
•
Major, indicating service-affecting errors. This event indicates that a major service is damaged or
lost, but the existing traffic is not affected.
•
Minor, indicating non-service affecting errors or errors on a remote node. Corrective action is
appropriate to prevent a serious fault from developing. An example is a fan failure, where no
subscribers are immediately affected, but calamity could result if the situation persists. Note that an
accumulation of lower-level alarms does equal a higher-level alarm.
The dspclkalms command is part of a hierarchy of troubleshooting commands you can execute on the
PXM45 or a service module. Frequently, dspclkalms follows the higher-level command dspndalms.
The dspndalms command shows a variety of alarms within the switch and helps isolate the problem.
The dspndalms and dspclkalms commands run on the PXM45. If the errored clock source appears to
be on a service module, you can cc to the CLI of that card and execute a variety of alarm commands and
other troubleshooting commands.
