如何创建一个设置VLAN的流量？

Question

我想做以下等效：

sudo ovs-ofctl add-flow s1 table=2,metadata=1379878762,actions=push_vlan:0x8100,mod_vlan_vid:4000,output:6,goto_table:4 -O openflow13 

我怎样才能做到这一点opendaylight java代码？我试着基于我能找到的一些例子，但没有流动出现，或者有时需要足够的调整，我可以让一部分流出现（我永远无法看到输出动作）。我正在使用碳（最新版本的碳）来开发我的产品。是否值得切换到夜间快照？

当我用opendaylight这样做时，我发现任何与vlan有关的操作都不会出现在我的流程中。流程中只出现goto。

=== UPDATE ===

我用下面的Java代码来设置和创建VLAN标签（由下面的答案建议）：

private static Instruction createSetVlanAndOutputToPortInstructions(int vlanId, 
     String outputPortUri) { 

    List<Action> actionList = new ArrayList<>(); 
    ActionBuilder ab = new ActionBuilder(); 

    Integer VLAN_ETHERTYPE = 0x8100; 
    ActionBuilder actionBuilder = new ActionBuilder(); 

    //push vlan 
    Action pushVlanAction = actionBuilder 
     .setOrder(0).setAction(new PushVlanActionCaseBuilder() 
      .setPushVlanAction(new PushVlanActionBuilder() 
       .setEthernetType(VLAN_ETHERTYPE) 
        .build()) 
        .build()) 
       .build(); 
    actionList.add(pushVlanAction); 

    //set vlan id 

    SetVlanIdActionBuilder tab = new SetVlanIdActionBuilder(); 
    tab.setVlanId(new VlanId((int) vlanId)); 
    SetVlanIdActionCaseBuilder vidcb = new SetVlanIdActionCaseBuilder(); 
    vidcb.setSetVlanIdAction(tab.build()); 
    Action setVlanIdAction = actionBuilder.setOrder(1).setAction(vidcb.build()).build(); 



    OutputActionBuilder output = new OutputActionBuilder(); 
    output.setMaxLength(Integer.valueOf(0xffff)); 

    Uri controllerPort = new Uri(outputPortUri); 
    output.setOutputNodeConnector(controllerPort); 

    ab = new ActionBuilder(); 
    ab.setKey(new ActionKey(0)); 
    ab.setAction(new OutputActionCaseBuilder().setOutputAction(output.build()).build()); 
    ab.setOrder(2); 
    actionList.add(ab.build()); 

    ApplyActionsBuilder aab = new ApplyActionsBuilder(); 

    aab.setAction(actionList); 

    InstructionBuilder ib = new InstructionBuilder(); 
    ib.setKey(new InstructionKey(0)); 
    ib.setInstruction(new ApplyActionsCaseBuilder().setApplyActions(aab.build()).build()); 

    return ib.build(); 
} 

，创建一个流规则的代码在这里：

FlowBuilder tagPacketFlow = new FlowBuilder().setTableId((short) tableId) 
      .setFlowName("metadataMatchSetVlanTagSendToPortAndGoToStripVlanTagTable").setId(flowId) 
      .setKey(new FlowKey(flowId)).setCookie(flowCookie); 
    MatchBuilder matchBuilder = new MatchBuilder(); 
    createMetadataMatch(matchBuilder, flowCookie.getValue()); 

    InstructionBuilder ib = new InstructionBuilder(); 
    Instruction createVlanTag = FlowUtils.createSetVlanAndOutputToPortInstructions(
      SdnMudConstants.MUD_RULE_HIT_LABEL, outputPortUri); 

    InstructionsBuilder insb = new InstructionsBuilder(); 
    ArrayList<Instruction> instructions = new ArrayList<Instruction>(); 
    instructions.add(createVlanTag); 
    Instruction gotoInstruction = ib.setInstruction(new GoToTableCaseBuilder() 
      .setGoToTable(new GoToTableBuilder().setTableId(SdnMudConstants.STRIP_VLAN_RULE_TABLE).build()).build()) 
      .setOrder(3) 
      .setKey(new InstructionKey(0)).build(); 
    instructions.add(gotoInstruction); 

    insb.setInstruction(instructions); 
    tagPacketFlow.setMatch(matchBuilder.build()).setInstructions(insb.build()) 
      .setPriority(35).setBufferId(OFConstants.ANY) 
      .setHardTimeout(time).setIdleTimeout(0).setFlags(new FlowModFlags(false, false, false, false, false)); 

在调用中openvswitch我看到这样的代码：

cookie=0x523f476a, duration=0.012s, table=2, n_packets=0, n_bytes=0, hard_timeout=30000, priority=35,metadata=0x523f476a actions=goto_table:3 

下面是从与该流的配置数据存储转储：

{ 
         "buffer_id": 4294967295, 
         "cookie": 1379878762, 
         "flags": "", 
         "flow-name": "metadataMatchSetVlanTagSendToPortAndGoToStripVlanTagTable", 
         "hard-timeout": 30000, 
         "id": "toaster.nist.gov/42", 
         "idle-timeout": 0, 
         "instructions": { 
          "instruction": [ 
           { 
            "go-to-table": { 
             "table_id": 3 
            }, 
            "order": 0 
           } 
          ] 
         }, 
         "match": { 
          "metadata": { 
           "metadata": 1379878762 
          } 
         }, 
         "priority": 35, 
         "table_id": 2 
        } 

所以VLAN设置只是不见了。

==== UPDATE 1 ====

我提交事务登录之前的流动。这里是设置VLAN指令：

ApplyActionsCase [_applyActions=ApplyActions 
     [_action=[Action [_action=PushVlanActionCase 
     [_pushVlanAction=PushVlanAction [_ethernetType=33024, 
     _vlanId=VlanId [_value=1001], augmentation=[]], augmentation=[]], 
    _key=ActionKey [_order=0], _order=0, augmentation=[]], 
     Action [_action=SetVlanIdActionCase[_setVlanIdAction=SetVlanIdAction 
    [_vlanId=VlanId [_value=1001], augmentation=[]], 
    augmentation=[]], _key=ActionKey [_order=1], _order=1, 
    augmentation=[]], Action [_action=OutputActionCase 
    [_outputAction=OutputAction [_maxLength=65535, 
    _outputNodeConnector=Uri [_value=openflow:1:6], 
     augmentation=[]], augmentation=[]], 
    _key=ActionKey [_order=2], _order=2, 
     augmentation=[]]], augmentation=[]], augmentation=[]] 

我看不出有什么问题。

当我删除转到这里遵循的XML模式： https://wiki.opendaylight.org/view/Editing_OpenDaylight_OpenFlow_Plugin:End_to_End_Flows:Example_Flows#Push_VLAN

它只能在没有goto的情况下运行。换句话说，如果我删除goto，我可以在配置数据存储中看到推送流。如果我把goto放进去，只会出现goto。

我看到有关opendaylight soutbound VLAN流量的问题跟踪一个问题被破坏，但它似乎已被固定在2014年（？）。

这是固定在氮气中，我怎么能提交一个bug反对opendaylight？

Answer 1

试试这个：

Integer VLAN_ETHERTYPE = 0x8100; 
ActionBuilder actionBuilder = new ActionBuilder(); 
List<Action> actions = new ArrayList<>(); 

//push vlan 
Action pushVlanAction = actionBuilder 
    .setOrder(0).setAction(new PushVlanActionCaseBuilder() 
     .setPushVlanAction(new PushVlanActionBuilder() 
      .setEthernetType(VLAN_ETHERTYPE) 
       .build()) 
       .build()) 
      .build(); 
actions.add(pushVlanAction); 

//set vlan id 
Action setVlanIdAction = actionBuilder 
    .setOrder(1).setAction(new SetFieldCaseBuilder() 
     .setSetField(new SetFieldBuilder() 
      .setVlanMatch(new VlanMatchBuilder() 
       .setVlanId(new VlanIdBuilder() 
        .setVlanId(new VlanId(vlanID)) 
        .setVlanIdPresent(true) 
       .build()) 
      .build()) 
     .build()) 
    .build()) 
    .build(); 
actions.add(setVlanIdAction); 

然后，您需要将您的行为添加到您的指示，以下列方式：

//ApplyActions 
ApplyActions applyActions = new ApplyActionsBuilder().setAction(actions).build(); 

//Instruction 
Instruction applyActionsInstruction = new InstructionBuilder() 
     .setOrder(0).setInstruction(new ApplyActionsCaseBuilder() 
       .setApplyActions(applyActions) 
       .build()) 
      .build();
