Openvswitch 配置端口镜像
1 #Create a dummy interface that will recieve mirrored packets
modprobe dummy
ip link set up dummy0
modprobe dummy
#Add the dummy interface to the bridge in use
2 添加端口到openvswitch中
ovs-vsctl add-port br0 dummy0
3 做端口镜像
ovs-vsctl
-- --id=@m create mirror name=mirror0
-- add bridge br0 mirrors @m
ovs-vsctl list port dummy0
d3427810-8e68-40af-99c0-8cb935af9882
ovs-vsctl set mirror mirror0
output_port=d3427810-8e68-40af-99c0-8cb935af9882
ovs-vsctl set mirror mirror0 select_all=1
测试
tcpdump –i dummy0
