Alex: 1. ~ tc qdisc add dev eth0 root handle 1: prio bands 4 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.
