Hi When I list all the qdisc with tc command it is not possible to see the parent of the qdisc. An example by the book. # tc qdisc add dev eth0 root handle 1: htb default 30 # tc class add dev eth0 parent 1: classid 1:1 htb rate 6mbit burst 15k # tc class add dev eth0 parent 1:1 classid 1:10 htb rate 5mbit burst 15k # tc class add dev eth0 parent 1:1 classid 1:20 htb rate 3mbit ceil 6mbit burst 15k # tc class add dev eth0 parent 1:1 classid 1:30 htb rate 1kbit ceil 6mbit burst 15k # tc qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10 # tc qdisc add dev eth0 parent 1:20 handle 20: sfq perturb 10 # tc qdisc add dev eth0 parent 1:30 handle 30: sfq perturb 10 (taken from the lartc howto) > tc -d qdisc list qdisc sfq 30: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 10sec qdisc sfq 20: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 10sec qdisc sfq 10: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 10sec qdisc htb 1: dev eth0 r2q 10 default 30 direct_packets_stat 7190 ver 3.14 if I try the same with class I get the parent of the classes > tc -d class list dev eth0 class htb 1:1 root rate 6Mbit ceil 6Mbit burst 15Kb/8 mpu 0b cburst 9463b/8 mpu 0b level 7 class htb 1:10 parent 1:1 leaf 10: prio 0 quantum 65536 rate 5Mbit ceil 5Mbit burst 15Kb/8 mpu 0b cburst 8151b/8 mpu 0b level 0 class htb 1:20 parent 1:1 leaf 20: prio 0 quantum 39321 rate 3Mbit ceil 6Mbit burst 15Kb/8 mpu 0b cburst 9463b/8 mpu 0b level 0 class htb 1:30 parent 1:1 leaf 30: prio 0 quantum 1000 rate 1Kbit ceil 6Mbit burst 15Kb/8 mpu 0b cburst 9463b/8 mpu 0b level 0 I have looked at the tc code, and it seems that parent information should be available for qdisc. But t->tcm_parent is NULL and therefor nothing printed.
