A value of 'primary(2)' indicates that OFDM channel is assigned to be the CM's primary downstream channel. A value of 'backupPrimary(3)' indicates that the OFDM channel is assigned to be the CM's backup primary downstream channel. A value of 'nonPrimary(4)' indicates the OFDM channel is not assigned to be CM's primary or backup primary downstream channel.

What is docsIf31RxChStatusPrimaryDsIndicator?

Tells you whether this downstream OFDM channel is the modem's primary channel, its backup primary, or just a non-primary bonded channel, returned as primary(2), backupPrimary(3), or nonPrimary(4). An admin polling this can quickly identify which physical channel actually carries the modem's registration and control traffic versus which are only used for bonded throughput.
