This chapter is a reference for the QSFP-DD configuration and status commands:

Use this command to select the application ID to be configured for this QSFP-DD module.

Use the no parameter with this command to remove this configuration. If no application is configured then application ID 1 will be selected as per module default.

QSFP-DD mode

By default, application ID 1 is selected.

This command was introduced before OcNOS version 6.1.0.

Use this command to set the high alarm threshold value for the Tx FDD, Tx FED, Rx FDD, Rx FED, Tx power, Rx Total Power, and Rx Signal Power performance monitoring parameters. High alarm threshold is the highest parameter value for the 400G transceiver to operate safely and reliably. For FEC Detected Degrade (FDD) and FEC Excessive Degrade (FED) monitoring, this command sets the active threshold. FDD suggests that the FEC has detected errors in data transmission. The alarm notification is triggered if the average BER exceeds the configured FDD value.

For more information, refer to the command reference page for ha in the 400G PM Alarm section of the OcNOS Key Feature document, Release 6.4.1.

Use this command to set the high warning threshold value for Tx power, Rx Total Power, and Rx Signal Power. High warning threshold is the highest parameter value for the 400G transceiver, exceeding which the transceiver performance and operational issues can occur.

For more information, refer to the command reference page for hw in the 400G PM Alarm section of the OcNOS Key Feature document, Release 6.4.1.

Use this command to set the low alarm threshold value based on the vendor-specific threshold for all the performance monitoring parameters Tx FDD, Tx FED, Rx FDD, Rx FED, Tx power, Rx Total Power, and Rx Signal Power threshold value. Low alarm threshold is the lowest parameter value for the 400G transceiver to operate with reliability. For FDD and FED monitoring this command sets the clear threshold.

For more information, refer to the command reference page for la in the 400G PM Alarm section of the OcNOS Key Feature document, Release 6.4.1.

Use these commands to configure the PRBS pattern generator/checker type to be used for diagnostics of the QSFP-DD module host/media side and to configure the PRBS pattern generator/checker location (pre-fec/post-fec) on the QSFP-DD module host/media side. If the generator/checker pattern type and location are supported by the QSFP-DD module this will enable the selected function.

Use the no parameter to remove this configuration and disable the generator/checker function.
