Service-Affecting Protection
Running diagnostics on the C4/c CMTS modules is potentially service affecting, therefore, a built in safeguard prevents the
user from initiating a diagnostic until the selected module is first taken Out-of-Service (OOS). If a user attempts to perform
a diagnostic on a module without first taking that module OOS, the diagnostic attempt will fail, and a warning message will
result.
System Log
All diagnostic commands and results are logged to the system log (syslog) automatically. See also
These events are also sent to the same terminal display associated with the CLI session.
Note: Diagnostic logs are viewable at priority level 7 (information). They can be viewed via syslog, local log, console or
monitor as long as this priority level is enabled. Refer to
(page 1028) for additional information.
Take Module Out-of-Service
Prior to performing a diagnostic on a module, the module must be taken OOS. See the procedure that follows.
To Take a Module Out of Service
1.
Determine the status of all modules by executing the following command:
show linecard status
An output similar to the following example will result:
