Probably the kernel module you're using doesn't support meters. > One important thing to mention here is that when I set the type of > switch to netdev like this: > > #ovs-vsctl set bridge br0 datapath_type=netdev > > I can add meters without any error. What's the reason? Each datapath has its own meter implementation, so when you switch datapaths you get different behavior. > There's one problem with this as well, I cannot achieve throughput > more than 500Mbps on 1Gbps link once I set the datapath type to > netdev. Probably you should use DPDK if you want high performance from the userspace datapath. _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
