- 檢查Pica OS的版本 (only for L2/L3 mode)
#cli - 設定下次開機預設使用的是OVS mode or L2/L3 mode
#sudo picos_boot - 新增OpenFlow Bridge br1
#ovs-vsctl add-br br1 -- set bridge br1 datapath_type=pica8 - 設定br1的OpenFlow Version

Ryu REST API 不同Match Field的下法 Part 2
我已經儘全力了，最右邊還是很大一格，不會自己換行，大家可以用複製的，就可以看到完整的語法了。
| Index | Field | Ryu Rest API 語法 |

curl -X POST -d '{"dpid":"0000000000000001", "priority":"32766","match":{"eth_type":2048,"ip_proto":1,"icmpv4_type":1}, "actions":[{"type":"OUTPUT","port":2}]}' http://127.0.0.1:8080/stats/flowentry/add |

套用封包產生器packETH於mininet OpenFlow環境
學會安裝封包產生器之後，免不了要打打看封包，這裡介紹如何將封包產生器和mininet結合
1. 首先，參考這篇，將Ryu&WEB GUI啟動起來，但是啟動RYU的指令，要換成下面這行，OpenFlow_13才支援等下要作的Push Vlan喔。
#./bin/ryu-manager --verbose --observe-links ryu/topology/switches.py ryu/app/rest_topology.py ryu/app/ofctl_rest.py ryu/app/simple_switch_13.py
2. 接著參考這裡，mininet啟動起來。指令換成下面這行，如此啟動起來的mininet才支援OpenFlow13。

在RYU上使用Rest API控制flow entry part 1/2 (match field 沒有mask)
import了SDN hub的VM後，總是會想要試看看能不能下個Flow Entry，
現在就來試看看如何手動設定flow entry。
1. 啟動SDN HUB VM內的mininet。
#sudo mn --controller=remote --switch ovsk,protocols=OpenFlow13
