Hi All,
Looking for some feedback in my test setup...
Can you please review my setup and let me know how to improve my application
of the qdiscs? I've been applying manually, but I'm not sure that is the best
method, or if the values really make sense. Sorry if this has been covered ad
nauseum in codel or bloat threads over the past 4+ years...
I've been capturing packets on a dedicated monitor box using the following
method:
tshark -i moni1 -w <file>
where moni1 is ath9k on channel 149 (5745 MHz), width: 40 MHz, center1: 5755
MHz
The system under test is a lanforge ath10k ap being driven by another
lanforge system using ath9k clients to associate and run traffic tests.
The two traffic tests I'm running are:
1. netperf-wrapper batch consisting of: tcp_download, tcp_upload,
tcp_bidirectional, rrul, rrul_be and rtt_fair4be on 4 sta's.
2. lanforge wifi capacity test using tcp-download incrementing 4 sta's per
minute up to 64 sta's with each iteration attempting 500Mbps download per x
number of sta's.
what results are you getting? and what results are you hoping to get to?

The qdiscs I am using are applied to the virtual ap interface which is the
egress interface for download tests. I also applied the same qdisc to the
ap's eth1 for the few upload tests. Is this sane?
qdiscs used, deleting each before trying the next:
1. default pfifo_fast
2. tc qdisc add dev vap1 root fq_codel
3. tc qdisc add dev vap1 root fq_codel target 5ms interval 100ms noecn
4. tc qdisc add dev vap1 root fq_codel limit 2000 target 3ms interval 40ms
noecn
Any suggestions you have would be helpful.
Thanks,
Isaac
