Open GoogleCodeExporter opened 8 years ago

Sorry for Spam, I could not get access to correct site 
https://github.com/esnet/iperf/issues
hence raising issue here... very sorry for that.... 

What steps will reproduce the problem?
1. Install iperf3.0 beta5 onto Redhat Linux system
2. Make a LTE call with IPV6 PDN type(so UE IP is IPV6)
3. Now send packets using iperf3 to UE IP with DSP marking as AF21 using below 
command
 ./iperf3 -6 -c 1234::9:0:0:1ceb:e0b0 -S 0x48
or
./iperf3 -6 -c 1234::9:0:0:1ceb:e0b0 -S 72

Check the DSCP value in TCPDUMP and observed as BE instead as AF21
