serialisation qos on ethernet

Unanswered Question
Feb 7th, 2008

I have metro service from provider, using 512k speed links (directly connected to ethernet or using ethernet subinterfaces). In order to setup qos on low spped links (<768kbits), it is recomended to use LFI. I know how to do it on FR links (MLPPP on virtual-template interface), but .... how to do this on ethernet interface?

br

I have this problem too.

LFI It is not possible on ethernet. Also, you may need hierarchical QoS config to set priority on ethernt. Write back if you need an example.

Hope this helps, please rate post if it does!
