Brocade Communications Systems 6650 manual Viewing optical transceiver thresholds

Digital optical monitoring 9

NOTE

The show optic function takes advantage of information stored and supplied by the manufacturer of the SFP, SFP+, and QSFP+ transceiver. This information is an optional feature of the Multi-Source Agreement standard defining the optical interface. Not all component suppliers have implemented this feature set. In such cases where the SFP, SFP+, and QSFP+ transceiver does not supply the information, a “Not Available” message will be displayed for the specific port on which the module is installed.

The following table describes the information displayed by the show optic command.

TABLE 48	Output from the show optic command
Field		Description
Port		The Brocade port number.
Temperature		• The operating temperature, in degrees Celsius, of the optical
		transceiver.
		• The alarm status, as described in Table 49.
Tx Power		• The transmit power signal, in decibels (dB), of the measured power
		referenced to one milliwatt (mW).
		• The alarm status, as described in Table 49.
Rx Power		• The receive power signal, in decibels (dB), of the measured power
		referenced to one milliwatt (mW).
		• The alarm status, as described in Table 49
Tx Bias Current		• The transmit bias power signal, in milliamperes (mA).
		• The alarm status, as described in Table 49.

For Temperature, Tx Power, Rx Power, and Tx Bias Current in the show optic command output, values are displayed along with one of the following alarm status values: Low-Alarm, Low-Warn, Normal, High-Warn or High-Alarm. The thresholds that determine these status values are set by the manufacturer of the optical transceivers. Table 49 describes each of these status values.

TABLE 49	Alarm status value description
Status value	Description
Low-Alarm	Monitored level has dropped below the "low-alarm" threshold set by the manufacturer of the
	optical transceiver.
Low-Warn	Monitored level has dropped below the "low-warn" threshold set by the manufacturer of the
	optical transceiver.
Normal	Monitored level is within the "normal" range set by the manufacturer of the optical transceiver.
High-Warn	Monitored level has climbed above the "high-warn" threshold set by the manufacturer of the
	optical transceiver.
High-Alarm	Monitored level has climbed above the "high-alarm" threshold set by the manufacturer of the
	optical transceiver.

Viewing optical transceiver thresholds

The thresholds that determine the alarm status values for an optical transceiver are set by the manufacturer of the SFP, SFP+, and QSFP+. To view the thresholds for a qualified optical transceiver in a particular port, use the show optic threshold command as shown below.
