I would like to configure AQM PIE by using tc-qdisc, but at the same time I would like to limit the bandwidth to 1Mb/s.
I have used similar configuration with fq_codel, i.e. I have limited the bandwidth by using htb, and later configured fq_codel for the leaf class, as it is done in this example https://www.linux.com/community/blogs/133-general-linux/879656-qos-in-linux-with-tc-and-filters
So for pie I do:
tc qdisc add dev eth0 handle 1: root htb default 11 tc class add dev eth0 parent 1: classid 1:1 htb rate 1000kbit ceil 1000kbit tc class add dev eth0 parent 1:1 classid 1:11 htb rate 1000kbit ceil 1000kbit tc qdisc add dev eth0 parent 1:11 pie
However I get "qdisc uknown" message and for example when I try to change any arguments of pie, I get an error: Unknown qdisc "pie", hence option "alpha" is unparsable.
Is it possible to use pie and limit the bandwidth at the same time?
Thank you in advance for any help.
