Re: Cannot get htb & prio working together.

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.

                          ^^^^ you mean 20: here

The last two filters need to have 20: as parent, if you want to keep
each filter inside a single qdisc.
