Even with the bandwidth setting for TC 0 reduced to 10, TC 1 increased to 30, and TC 3 increased to 60 to accommodate priorities 6 and 7 that were not explicitly assigned there, it turns out to be lower priorities, if any, that manage to get all their sent messages received, based on analysis of a tcpdump on the receiver side.
Also, I tried “man vconfig” and “which vconfig” and came up empty. I guess I could look into “apt-get install” if needed, but since I’m generating the outgoing frames with explicit VLAN tags, I shouldn’t need it for my purposes, should I?
My first impression of layer 2 QoS was that it was relatively straightforward, but that seems not to be the case.
