PRTG Network Monitor 18.104.22.1689 Trial.
Using the QoS Round trip sensor with DSCP marking set, the packets going to the remote probe have the DSCP value but the packets returning from the remote probe have DSCP = 00.
The QoS Scheduler is present on the network adapters of both (Windows 7) PCs.
Also, DSCP marking works correctly on the remote PC when using the Ostinato traffic generator to generate marked traffic. (http://code.google.com/p/ostinato/).
I am implementing PRTG Network Monitor for general monitoring and to run the QoS Round trip sensor in an IP Telephony environment on Monday (NZ).
Any input on how to have the sensor apply DSCP maring on the return traffic will be appreciated.
