This counter tallies the total number of IP packets the router has received over its satellite interfaces. This is the primary indicator that the satellite RF and demodulator chain is actually delivering usable IP traffic downstream, complementing RF-layer metrics like Eb/No; a locked demodulator with healthy signal quality but a stalled counter here points to a problem above the physical layer, such as HDLC framing or flow ID mismatch. On a remote site expecting continuous data delivery, this counter should increment steadily; if it stops while cdd564RxAlarm still reads rxTrafficOK(0), the fault likely lies in packet processing rather than the RF link itself.
