1.

This command created 4 priority classes 1:1 - 1:4
2. Attach your pfifo qidisc to these so basically not on the 1:0
~ tc qdisc add dev eth0 parent 1:0 handle 10: pfifo limit 100
- should be tc qdisc add dev eth0 parent 1:1 handle 10: pfifo
limit 100
3.
filter traffic to 1:1 - 1:4 NOT ON THE PFIFO qdisc
so...
... Flowid 1:1 not 10
Hope this helps.
Thanks a lot, it did the trick.
In this configuration, 10: will have the highest priority and 40:
lowest, right ?

Subject: [LARTC] strict priority
I'm trying to configure 4 queues with strict priorities based on DSCP.
I tried to following commands, but it seems that the filters I defined
have no effect
tc qdisc add dev eth0 root handle 1: prio bands 4 tc qdisc add dev eth0
parent 1:0 handle 10: pfifo limit 100 tc qdisc add dev eth0 parent 1:1
handle 20: pfifo limit 100 tc qdisc add dev eth0 parent 1:2 handle 30:
pfifo limit 100 tc qdisc add dev eth0 parent 1:3 handle 40: pfifo limit
100 tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip
tos
224 0xff flowid 10:
tc filter add dev eth0 parent 1:0 protocol ip prio 2 u32 match ip tos
160 0xff flowid 20:
tc filter add dev eth0 parent 1:0 protocol ip prio 3 u32 match ip tos 0
0xff flowid 30:
tc filter add dev eth0 parent 1:0 protocol ip prio 4 u32 match ip tos
32 0xff flowid 40:
Any suggestions ?
