Re: [LARTC] Cannot get htb & prio working together.

[Michael Davidson <michael@bbd.co.za>]

Hi,

I've tried the multi tier filtering as suggested, but It didn't do the 
trick unfortunately. The filters were accepted at the command line but 
when but when I do  "tc -s -d filter show dev eth0" the only filters 
displayed are those with "root" as the parent. Below is my current script.

tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:1 htb rate 120kbit
tc class add dev eth0 parent 1:1 classid 1:20 htb rate 30kbit ceil 120kbit
tc qdisc add dev eth0 parent 1:20 handle 20: prio
#
#Note: With a "prio" qdisc the class ID's of 20:1 to 3 are automatically 
provided
#
tc qdisc add dev eth0 parent 20:1 handle 201: sfq
tc qdisc add dev eth0 parent 20:2 handle 202: sfq
tc qdisc add dev eth0 parent 20:3 handle 203: sfq

tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dport 
22 0xffff flowid 1:20
tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dport 
23 0xffff flowid 1:20
tc filter add dev eth0 parent 20:0 protocol ip prio 1 u32 match ip dport 
22 0xffff flowid 20:1
tc filter add dev eth0 parent 20:0 protocol ip prio 1 u32 match ip dport 
23 0xffff flowid 20:3

Regards Mike.
