Viewing the results of the cable analysis
To display the results of the cable analysis, enter a command such as the following at the Privileged
EXEC level of the CLI:
Syntax: show cable-diag tdr <port-num>
Table 11 defines the fields shown in the command output.
Digital Optical Monitoring
NOTE
Digital Optical Monitoring is not supported for FGS-STK devices running release 05.0.01.
You can configure your Foundry device to monitor optical transceivers in the system, either globally
or by specified port. When this feature is enabled, the system monitors the temperature and signal
power levels for the optical transceivers in the specified ports. Console messages and syslog
messages are sent when optical operating conditions fall below or rise above the XFP or SFP
manufacturer’s recommended thresholds. For more information about digital optical monitoring,
refer to the FastIron Configuration Guide.
