prbs

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.
