Hi all,
First, let me say I've been most impressed with how quickly and
professionally people on this list ask and answer questions.
Next, let me say that with which I need help is properly configuring strict
PQ, and gathering certain stats. Specifically:
- I need to create a priority queue with four queues (let's say they are of
high, medium, normal, and low priority)
- I need to use tc filters such that:
- EF (0xB8) goes to the high priority queue
- AF21 (0x50) goes to the medium priority queue
- AF11 (0x28) goes to the normal priority queue, and
- BE traffic goes to the low priority queue
- For stat collection, I need to see:
- how many bytes and packets are in each of the four queues
- My configuration thus far is:
tc qdisc add dev eml_test root handle 1: prio bands 4 priomap 0 1 2 3
tc filter add dev eml_test parent 1:0 prio 1 protocol ip u32 match ip tos
0xb8 0xff flowid 1:1
tc filter add dev eml_test parent 1:0 prio 2 protocol ip u32 match ip tos
0x80 0xff flowid 1:2
tc filter add dev eml_test parent 1:0 prio 3 protocol ip u32 match ip tos
0x50 0xff flowid 1:3
tc filter add dev eml_test parent 1:0 prio 4 protocol ip u32 match ip tos
0x00 0xff flowid 1:4
__________
My questions are:
- What if anything is missing/requiring change in my config given the stated
requirements?
- What if any command should I use to view how many bytes and packets are in
each of the four queues?
Any help would be most appreciated.
