In the MIB cambiumRadioTable has entries for rx/tx bytes and packets, while cambiumClientTable has entries for cambiumClientIPAddress and tx/rx bytes and packets.
but they have 19 elements or Counter, I assume that one is the throughput of the ethernet interface, other the throughput of one wlan and so on, which one is the throughput of the interface? I attach here a pic of the output of the OIDs 1.3.6.1.2.1.2.2.1.16, and 1.3.6.1.2.1.2.2.1.10.
