Digital optical monitoring
You can configure your Brocade device to monitor optical transceivers in the system, either globally or
by specified ports. When this feature is enabled, the system will monitor 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 recommended thresholds.

Digital optical monitoring configuration limitations

A Brocade chassis device can monitor a maximum of 24 SFPs and 12 XFPs.
NOTE
A Brocade ICX 6650 device allows all ports to support Digital Optical Monitoring (DOM).

Enabling digital optical monitoring

To enable optical monitoring on all Brocade-qualified optics installed in the device, use the following
command.
device(config)#optical-monitor

Cable statistics
Meaning
The port that was tested.
The port current line speed.
The local link name. Refer to the previous local pair definition table.
The cable length when terminated, or the distance to the point of fault when the line is not up.
The remote link name.
The status of the link. This field displays one of the following:
• Terminated: The link is up.
• Shorted: A short is detected in the cable.
• Open: An opening is detected in the cable.
• ImpedMis: The impedance is mismatched.
• Failed: The TDR test failed.
