Digital optical monitoring
You can configure your 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, SFP, and SFP+ manufacturer’s
recommended thresholds. For more information about digital optical monitoring, refer to FastIron
Ethernet Switch Administration Guide.
