Is it possible to apply a value into the 802.1p field

[RobFantini]

we want prioritize network traffic at our switch . it uses cumulus linux and can prioritize traffic based on 802.1q .
that way from the KVM phone system just voip / voice would get a different value then rsync backups.

coming from pve , backups would get a lower value then other types of traffic, so we'd also need to know how assign priority at pve level .

so my question:
from a within a vm how can we adjust the 802.1p value for different processes? [ if even possible ].

thanks for reading .

33 its the vlan
