wondershaper is not throttling my bandwidth

Question

I'm on a dedicated server (proxmox-ve-2.6.32: 3.4-165 (running kernel: 2.6.32-42-pve)) with a 95th percentile rule and want do be sure to not break it. I have a 1gbit link and my contract offer me a 95th percentile on 100mbits. So I would like to limit my bandwith always to 100 mbits.

I've tried to use wondershaper without any sucess and need some help:

Any ideas?

Solution

I haven't found the way to fix this issue with wondershaper, but found an other way to do the same with ethtool :

ethtool -s eth0 speed 100 duplex full

Ahem. To clarify, this doesn't "do the same thing" although it does achieve what you want (limiting the speed to 100Mbps). It limits the NIC interface to 100Mbps (effectively disabling Gigabit) but isn't always an available option.
