hello everyone,
I have to configure qos on for video on the network, but unfortunately I have not found a guide to configure the qos for video,
My devices are, switches 2960, 3850 and ASA 5508.
If anyone can help, please advise.

Thanks for your time.
We would like to apply qos to skype for business and teams. I'm not sure what is the properly configuration regarding streaming.
What type of configuration do you suggest?

Hello,
in addition to the other posts, I would think that, since you use the ASA and that is probably the Internet facing device, the QoS would best be configured on the ASA. Skype uses the default DSCP values below, so if you configure your switches to trust the DSCP values coming from Skype, you can configure the QoS policy on the ASA as below. This is of course very generic, but might point you in the right direction:
Switch interfaces:
--> mls qos trust dscp
