Qos on CSR 3xxx

Wed Nov 24, 2021 5:10 am

Hi,
Hope all is well.
I need your help to do simple QoS to forward the voice packets (SIP packets) to PBX server with 1st priority as the diagram attached.
I have 2 Vlans, Users and Voice, and I am using CSR326-S24 as core switch, CSR326-S24 as servers switch, and CSR328-P24 as access switch.


Regards,
Nabil Alwan.

Hi,

Could anyone refer me to a web link to have at least the idea of doing QoS on 3xx switches?

Thanks in advance.

CRS 3XX SWITCHES MANUAL

https://help.mikrotik.com/docs/display/ ... s+switches

I think To the date CRS 3xx has not true QoS like other switch vendors:
no multiple hardware queues per port
no DCSP remark

I think a way to achieve your objective is to rate-limit another traffic leaving some capacity reserved (unusable by other traffic) for voip traffic

keep in mind all the clasification must be done in ingress
