halo all, i hope you can help within my QoS configuration here :
my topology is based on
http://openvswitch.org/support/config-cookbooks/qos-rate-limiting/
on Client1: br0, within port : tap0, tap1,
Client 2 : as measurement host, Ubuntu 12.04; iperf
as example, in tap0 i want to limit rate 15Mb
Ingress Policing Configuration
1.) enable kernel module
/usr/src/linux-headers-3.2.0-27-generic-pae/.config
CONFIG_BRIDGE=m
CONFIG_NET_SCH_INGRESS=m
CONFIG_NET_CLS_U32=m
CONFIG_NET_CLS_ACT=m
CONFIG_NET_CLS_BASIC=m
CONFIG_NET_ACT_POLICE=m
output:
root@ubuntu:~/ovs# lsmod | grep cls_basic
cls_basic 12802 0
root@ubuntu:~/ovs# lsmod | grep sch_ingress
sch_ingress 12746 0
root@ubuntu:~/ovs# lsmod | grep act_police
act_police 12804 0

2.) link to header
root@ubuntu:~/ovs# ls -ald /lib/modules/3.2.0-27-generic-pae/build
lrwxrwxrwx 1 root root 43 Jul 6 12:10
/lib/modules/3.2.0-27-generic-pae/build ->
/usr/src/linux-headers-3.2.0-27-generic-pae

3.) ingress policy
ovs-vsctl set Interface tap0 ingress_policing_rate=15000
4.) output OVS
root@ubuntu:~/ovs# ovs-vsctl list interface tap0
