Plot for my config is too simple...

Here are my sample rules:

tc qdisc add dev eth0 root handle 1: htb default 9
tc class add dev eth0 parent 1: classid 1:2 htb rate 1mbit
tc qdisc add dev eth0 parent 1:2 fq_codel ecn

tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst 10.0.2.7/32 classid 1:2  # every Egnyte ip address
tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst 10.0.2.8/32 classid 1:2
# no rules for 1:9, other traffic is unlimited

And here's the tool's output:

I would expect to see:

• other (unmatched) traffic for default classid 1:9 via rule handle 1: htb default 9
• those back solid arrows you have in your example.png

Hi Dima, I unfortunately no longer work with tc and do not maintain this tool. If you decide to fix this yourself, I am always happy to accept a PR!
