1 如何添加OVS和PORT;
ovs-vsctl add-br br0
ovs-vsctl del-br br0
ovs-vsctl list-br
ovs-vsctl add-port br0 eth0
ovs-vsctl set port eth0 tag=1//vlan id
ovs-vsctl del-port br0 eth0
ovs-vsctl list-ports br0
ovs-vsctl show //顯示所有端口的vlan屬性
2.如何配置QOS，比如隊列和限速;
sudo ovs-vsctl -- set Port eth2 qos=@newqos -- --id=@newqos create QoS type=linux-htb other-config:max-rate=1000000000 queues=0=@q0,1=@q1 -- --id=@q0 create Queue dscp =1 other-config:min-rate=100000000 other-config:max-rate=100000000 -- --id=@q1 create Queue other-config:min-rate=500000000
ovs-vsctl clear Port eth2 qos
sudo ovs-vsctl list qos
sudo ovs-vsctl destroy qos _uuid
sudo ovs-vsctl list qos
sudo ovs-vsctl destroy queue _uuid
3 如何配置流鏡像;
sudo ovs-vsctl -- set Bridge br-int mirrors=@m -- --id=@tap6a094914-cd get Port tap6a094914-cd -- --id=@tap73e945b4-79 get Port tap73e945b4-79 -- --id=@tapa6cd1168-a2 get Port tapa6cd1168-a2 -- --id=@m create Mirror name=mymirror select-dst-port=@tap6a094914-cd,@tap73e945b4-79 select-src-port=@tap6a094914-cd,@tap73e945b4-79 output-port=@tapa6cd1168-a2
sudo ovs-vsctl remove Bridge br0 mirrors mymirror
sudo ovs-vsctl clear Bridge br-int mirrors
4 如何配置流監控sflow;
sudo ovs-vsctl -- --id=@s create sFlow agent=eth2 target=\"10.0.0.1:6343\" header=128 sampling=64 polling=10 -- set Bridge br-int sflow=@s
sudo ovs-vsctl -- clear Bridge br-int sflow
5 如何配置流規則；
sudo ovs-ofctl add-flow br-int idle_timeout=0,in_port=2,dl_type=0x0800,dl_src=00:88:77:66:55:44,dl_dst=11:22:33:44:55:66,nw_src=1.2.3.4,nw_dst=5.6.7.8,nw_proto=1,tp_src=1,tp_dst=2,actions=drop
sudo ovs-ofctl del-flows br-int in_port=2 //in_port=2的所有流規則被刪除
sudo ovs-ofctl dump-ports br-int
sudo ovs-ofctl dump-flows br-int
sudo ovs-ofctl show br-int //查看端口號
支持字段還有nw_tos,nw_ecn,nw_ttl,dl_vlan,dl_vlan_pcp,ip_frag，arp_sha,arp_tha,ipv6_src,ipv6_dst等;
支持流動作還有output：port，mod_dl_src/mod_dl_dst,set field等;
6 如何查看OVS的配置
ovs-vsctl list/set/get/add/remove/clear/destroy table record column [VALUE]
TABLE名有bridge,controller,interface,mirror,netflow,open_vswitch,port,qos,queue,ssl,sflow
7. 配置vxlan gre和ip address
ovs-vsctl add-port br-ex port -- set interface port type=vxlan options:remote_ip=192.168.100.3
ovsvsctladdport br-ex port set Interface port type=greoptions:remote_ip=192.168.100.3
ovsvsctladdport br-ex port tag=10 set Interface port type=internal//默認爲access
ifconfig port 192.168.100.1
8. 顯示並學習MAC
ovs-appctl fdb/show br-ex
9. 設置控制器地址
ovs-vsctl set-controller br-ex tcp:192.168.100.1:6633
ovs-vsctl get-controller br0
ovs-controller ptcp:6633:192.100.100.1
