Hi there,
I was trying to use nv2 qos on a p2mp architecture where ap and cpes are mikrotik devices, all of them equipped with RouterOs 5.25.
My needing is to give high priority to traffic coming and sent to a specific CPE among the others. reading the docs is not clear to me if nv2 qos queue are managing traffic coming from all the CPE or the we have instances of k-queues for each pair (CPE,AP). in other words : priority is applied among traffic related to single CPE or among CPEs?
I used as config reference , informations reported in http://wiki.mikrotik.com/wiki/Manual:Nv2#QoS_in_Nv2_network
I decided to use 4 queue (also tried 2 queues) , configured on the AP side :
/interface wireless
set 0 nv2-preshared-key=********* nv2-qos=frame-priority nv2-queue-count=4 nv2-security=enabled wireless-protocol=nv2
moreover my goal is to have among CPE on of them, with wlan ip 192.168.10.34 to be prioritized. So my prioritization design was to put traffic from AP sent to this CPE in the highest priority queue 3 (using mangle priority 3) while the others on lowest queue 0 (setting lowest priority 0 or 1. I tried both).
/ip firewall mangle
add action=set-priority chain=postrouting dst-address=192.168.10.34 new-priority=7 passthrough=no
add action=set-priority new-priority=1 chain=postrouting passthrough=no
The client side is just giving maximum priority to all traffic sent trough interface wlan1 linked to Ap .
/ip firewall mangle
add action=set-priority chain=postrouting new-priority=7 \
out-interface=wlan1
To test my configuration I used to ping internet hosts from CPE 192.168.10.34 before and after enabling the previous configurations but the ping latency was almost the same . I mean on a packet size set to 800 bytes , sent 100 times , the avergae rtt was the same about 110 ms.
My doubt now is … may be that the scope of the priority queue is the pair (Ap,CPE)? I mean there are 4 queues for every CPE registered on the Ap and traffic priorities are applied to traffic related to the single CPE? in other words is true that nv2 qos is not used to give priorities to CPE among the others but to traffic inside every cpe?
thanks a lot for your attention .
