<div>It was the aggregate on the circuit towards the lac I wanted to pwfq, I remember when I tried to do this on Cisco I could never match traffic that was l2tp encapsulated, we ended up l2tp tunnel switching the traffic to another lns and shaping the whole tunnel, one of my <font style="BACKGROUND-COLOR: #ffffff">colleagues has a working redback pwfq policy but the bandwidth shaping values don't exactly match reality, the difference appears to be the overhead of the l2tp etc. How does the redback Qos inside l2tp, does it match before encapsulation or is it doing some type of dpi.</font></div>

also apply pwfq to the egress circuit to the lac. If you try to do _both_<br>(subscriber and aggregate), be careful. There's no H-Qos for l2tp lns.<br><br>ta<br>Ian<br><br>_______________________________________________<br>
