VLAN QOS

Is it possibele to set up QOS based on Vlans assignments?

I want to guarantee that a certain vlans traffic is always sent first before all other traffic in times of congestion.

Is there a way to accomplish this?

Thanks!

VLAN QOS

You can configure service-policy with class which is matching particular subnet which you want to give a priority. Then in this policy aply particular DSCP settings and further treat this class as priority by these settings.

On ports you can configure valn-based QoS. SO all traffic entering those ports will refer to Service-policy attached to corresponding VLAN - thus needed settings will be applied on VLAN bases.

Just few examples can be found e.g here:
