I want to have around 1 Million htb tc classes. The simple structure of htb tc class, allow having only 64K classes at once. But, it is possible to make it more hierarchical using hierarchy of qdisc and classes. For this I tried something like this tc qdisc add dev eno2 root handle 100: htb tc class add dev eno2 parent 100: classid 100:1 htb rate 100Mbps tc class add dev eno2 parent 100: classid 100:2 htb rate 100Mbps tc qdisc add dev eno2 parent 100:1 handle 1: htb tc class add dev eno2 parent 1: classid 1:10 htb rate 100kbps tc class add dev eno2 parent 1: classid 1:20 htb rate 300kbps tc qdisc add dev eno2 parent 100:2 handle 2: htb tc class add dev eno2 parent 2: classid 2:10 htb rate 100kbps tc class add dev eno2 parent 2: classid 2:20 htb rate 300kbps What I want is something like: tc filter add dev eno2 parent 100: protocol ip prio 1 handle 0x00000001 fw flowid 1:10 tc filter add dev eno2 parent 100: protocol ip prio 1 handle 0x00000002 fw flowid 1:20 tc filter add dev eno2 parent 100: protocol ip prio 1 handle 0x00000003 fw flowid 2:10 tc filter add dev eno2 parent 100: protocol ip prio 1 handle 0x00000004 fw flowid 2:20 But I am unable to shape my traffic by any of 1:10, 1:20, 2:10 or 2:20. Can you please suggest, where is it going wrong? Is it not possible altogether? -Akshat
