我想做以下等效:如何創建一個設置VLAN的流量?
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
我怎樣才能做到這一點opendaylight java代碼?我試着基於我能找到的一些例子,但沒有流動出現,或者有時需要足夠的調整,我可以讓一部分流出現(我永遠無法看到輸出動作)。我正在使用碳(最新版本的碳)來開發我的產品。是否值得切換到夜間快照?
當我用opendaylight這樣做時,我發現任何與vlan有關的操作都不會出現在我的流程中。流程中只出現goto。
=== UPDATE ===
我用下面的Java代碼來設置和創建VLAN標籤(由下面的答案建議):
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();
}
,創建一個流規則的代碼在這裏:
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));
在調用中openvswitch我看到這樣的代碼:
cookie=0x523f476a, duration=0.012s, table=2, n_packets=0, n_bytes=0, hard_timeout=30000, priority=35,metadata=0x523f476a actions=goto_table:3
下面是從與該流的配置數據存儲轉儲:
{
"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設置只是不見了。
====結束UPDATE ====
==== UPDATE 1 ====
我提交事務登錄之前的流動。這裏是設置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=[]]
我看不出有什麼問題。

===更新=== 2
當我刪除轉到這裏遵循的XML模式: https://wiki.opendaylight.org/view/Editing_OpenDaylight_OpenFlow_Plugin:End_to_End_Flows:Example_Flows#Push_VLAN
它只能在沒有goto的情況下運行。換句話說,如果我刪除goto,我可以在配置數據存儲中看到推送流。如果我把goto放進去,只會出現goto。
====結束時更新2 ====
我看到有關opendaylight soutbound VLAN流量的問題跟蹤一個問題被破壞,但它似乎已被固定在2014年(?)。
這是固定在氮氣中,我怎麼能提交一個bug反對opendaylight?
不幸的是沒有工作。我的表仍然有:cookie = 0x523f476a,持續時間= 0.012s,表= 2,n_packets = 0,n_bytes = 0,hard_timeout = 30000,優先級= 35,元數據= 0x523f476a actions = goto_table:3。 – LostInTheFrequencyDomain
請參閱上面的更新。謝謝你的幫助。 – LostInTheFrequencyDomain
爲什麼setField需要一個VlanMatchBuilder()?我對編程模型感到困惑。 – LostInTheFrequencyDomain
