I have OVS 2.10.90. I want to know is it possible to add meter in kernel-space switch with 2.10.90 version of OVS?
I have Ubuntu 4.4.0-31-generic and I installed OVS 2.10.90 on it as follows. apt-get install git git clone https://github.com/openvswitch/ovs.git cd ovs apt install build-essential libssl1.0.0 libcap-ng-utils sudo add-apt-repository ppa:deadsnakes/ppa sudo apt-get update sudo apt-get install python2.7 libnuma-dev libtool autoconf automake wget python-six libvirt-bin sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt-get update sudo apt-get install g++-4.9 gcc-multilib apt-get install libpcap-dev apt-get install iperf ./boot.sh ./configure make make install #to use the kernel module that was shipped with ovs 2.10.90 config_file="/etc/depmod.d/openvswitch.conf" for module in datapath/linux/*.ko; do modname="$(basename ${module})" echo "override ${modname%.ko} * extra" >> "$config_file" echo "override ${modname%.ko} * weak-updates" >> "$config_file" done depmod -a #loading openvswitch /sbin/modprobe openvswitch export PATH=$PATH:/usr/local/share/openvswitch/scripts ovs-ctl start Then I ran following script to test meter function in kernel-space datapath: ovs-vsctl add-br br0 ovs-vsctl set bridge br0 protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13,OpenFlow14,OpenFlow15 ovs-ofctl -O OpenFlow15 add-meter br0 meter=100,kbps,band=type=drop,rate=300000 However I got this error.

I am not able to add meter. Please let me if someone tried it and have meter actually been implemented in kernel datapath in Open vSwitch 2.10.90? Best Regards, Ramzah Rehman
