I have : tc qdisc add dev eth0 root handle 1: prio bands 3 priomap 0 1 2 tc qdisc add dev eth0 parent 1:1 handle 2: pfifo limit 1024 tc qdisc add dev eth0 parent 1:2 handle 3: pfifo limit 1024 tc qdisc add dev eth0 parent 1:3 handle 4: pfifo limit 1024 Using tc I can filter out traffic based on UDP port and put it in a specific queue using: tc filter add dev eth0 parent 1:0 prio 1 u32 match ip dport 0x06B8 0xffff flowid 1:1. Is there anyway I can put the rest of the traffic in another queue other than the default one? The default queue coincides with the queue with the highest priority. Thanks, ..Ram
