Dear all, I have a linux box with two NICs: eth0 (10 Mbit) and pvc0 (64Kbit) (pvc over frame-relay with a WAN card). I have two kinds of traffic incoming on eth0: Best effort traffic (TOS=0) and VoIP traffic (TOS=5). I want to simply configure the linux box so that It priorizes the VoIP packets so that all VoIP packets are sent before transmitting the BE packets. Which command I need with tc? Looking at LARTC Howto It seems that I can match only packets with TOS 2,4,8 and 16... I didn''t understand very well that part...
