I have a Cisco 3750 switch with QoS configurations in place. I want to try using the CBQoS module but when I query the switch, PRTG shows 'No CBQoS Entries available'. This seems to be the same issue as this person:

I tried but I cannot reply to that thread so I have started this new one. Here are my QoS specifics:

Hi,
may you as mentioned in the other thread, please perform an SNMP walk against the OID 1.3.6.1.4.1.9.9.166.1.5.1.1 using the SNMP Tester.
What are the results?

I performed Custom OID & Walk with the string provided, here are my results. I have 2 Cisco devices I am trying to look at. As mentioned a 3750 switch, which is 192.168.84.1. Also a 3925 router, which is 192.168.84.35. I also performed a Scan Interfaces and the output was very long. Will that be helpful? I can post here or send it to you as an email attachment.

Hi,
it seems the switch/router is not providing the CBQoS data via SNMP correctly. This is why you are receiving the mentioned error message. May I ask you to consult the documentation of the device, if some special configuration is necessary here to provide the data via SNMP?
