ePMP3000 Maximum wireless Throughput

Products ePMP

Hi everyone,

I’m seeing something a bit confusing when querying SNMP on a Cambium ePMP 3000 access point.

Specifically, when I query the Wireless interface, the SNMP OID ifHighSpeed returns a value of 220 Mbps. This seems low considering that the ePMP 3000 is advertised to support up to 600 Mbps aggregate throughput under ideal conditions.

So I have a few questions:

  1. Does this ifHighSpeed value represent the maximum downlink capacity only, based on current RF conditions or link configuration?
  2. Is this value static or dynamic? In other words, is it hardcoded or estimated by the radio based on modulation, bandwidth, and other RF parameters?
  3. Are there any Cambium-specific OIDs available that provide:
  • Actual wireless capacity (DL/UL)
  • Real-time or estimated total throughput of the wireless link

Thanks in advance for your support and insights.

Best regards,

Hello @Mamadou_Idrissa_Maig,

unfortunately I can not find ifHighSpeed object in generic rfc1213 mib.
I suggest to use our native mib file from the latest SW release. MIB file download page.
In the object tree you will see cambiumPmp80211SystemMonitoring branch. There you can choose what exactly you want to monitor.
I have seen PRTG NMS configuring Cambium radios monitoring automatically and printing accurate graphs with statistics.

cnMaestro will be the best for your network monitoring and management. It is a solid native solution. It is in cloud and free of charge.

Thank you @aka
I’ll look into cambiumPmp80211SystemMonitoring as suggested.

Just to clarify:
What’s the real max aggregate throughput (Tx + Rx) for the ePMP 3000 ?

Thanks again!
