我想做相同的以下内容：
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
如何在opendaylight java代码中执行此操作？我试过基于我能找到的一些例子，但是没有流出现或有时有足够的调整我可以得到流的一部分出现（我永远看不到输出动作）。我正在使用Carbon（碳的最新版本）进行开发。是否值得切换到夜间快照？
当我使用opendaylight执行此操作时，我发现任何与vlan有关的操作都不会出现在我的流程中。只有goto出现在流程中。
=== UPDATE ===
我使用以下java代码来设置和创建vlan标记（通过以下答案建议）：
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));
调用代码后，我在openvswitch中看到了这个：
cookie=0x523f476a, duration=0.012s, table=2, n_packets=0, n_bytes=0, hard_timeout=30000, priority=35,metadata=0x523f476a actions=goto_table:3
以下是与此流程对应的配置数据存储区的转储：
{
"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设置刚刚消失了。

我在提交交易之前记录了流程。这是设置的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goto并遵循xml的模式时： https://wiki.opendaylight.org/view/Editing_OpenDaylight_OpenFlow_Plugin:End_to_End_Flows:Example_Flows#Push_VLAN
它只适用于没有goto。换句话说，如果我删除了goto，我可以看到配置数据存储区中的推送流程。如果我把goto放入，只有goto出现。

我在问题跟踪器中看到有关opendaylight soutbound中vlan流量被破坏的问题，但它似乎已于2014年修复（？）。
这是固定在氮气中，我怎么能提交针对opendaylight的错误？

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，您需要按以下方式将您的操作添加到说明中：
//ApplyActions
ApplyActions applyActions = new ApplyActionsBuilder().setAction(actions).build();
//Instruction
Instruction applyActionsInstruction = new InstructionBuilder()
.setOrder(0).setInstruction(new ApplyActionsCaseBuilder()
.setApplyActions(applyActions)
.build())
.build();

升级到氮气后，我发现我的问题消失了。因此，Carbon发布中似乎存在一个错误。不知道什么时候修好了。
