Two instructions into an apply in a flowMod

sbotkine — Mon, 14 Apr 2014 13:09:11 GMT

Hello,

I need to create the following apply instruction in a FlowMod:

[{"apply_actions":[{"output":5}, {"output":4294967293}]}]

4294967293 is the controller port.

With the following instructions:

Action action1 = ActionFactory.createAction(version, ActionType.OUTPUT, Port.CONTROLLER, ActOutput.CONTROLLER_NO_BUFFER);

Action action2 = ActionFactory.createAction(version, ActionType.OUTPUT, BigPortNumber.valueOf(5), ActOutput.CONTROLLER_NO_BUFFER);

InstrMutableAction apply = createMutableInstruction(PV,InstructionType.APPLY_ACTIONS);

apply.addAction(action2);

apply.addAction(action1);

List<Instruction> ins = new ArrayList<Instruction>();

ins.add((Instruction) apply.toImmutable());

It doesn't work.

However if I put port 5 and port 9 (for example)

Action action1 = ActionFactory.createAction(version, ActionType.OUTPUT, BigPortNumber.valueOf(9), ActOutput.CONTROLLER_NO_BUFFER);

Action action2 = ActionFactory.createAction(version, ActionType.OUTPUT, BigPortNumber.valueOf(5), ActOutput.CONTROLLER_NO_BUFFER);

InstrMutableAction apply = createMutableInstruction(PV,InstructionType.APPLY_ACTIONS);

apply.addAction(action2);

apply.addAction(action1);

List<Instruction> ins = new ArrayList<Instruction>();

ins.add((Instruction) apply.toImmutable());

It works.

Can you see a problem ?

Regards,

Serge

PS: [{"apply_actions":[{"output":5}, {"output":4294967293}]}] works sometimes depending on the selected "Match" on the flowmod. With a match like [{"eth_type":"arp"},{"arp_op":1}] it works, but for a match like [{"eth_type":"ipv4"},{"ip_proto":"udp"},{"udp_dst":98}] it doesn't work.

Serge,

Have you attempted the FlowMod in the RSDOC interface to see if you get the same behavior?

What switch (model and OS version) is this attempted on?

Hello Serge,

Doing a follow up to check if you get any chance to get relevant information as Scott had asked for.

Hi Serge

Out of curiosity on what kind of switch are you attempting it and what software version is it running ?

Kind Regards

Gerhard

switches are: HP 3500-24G and HP 3800-24G-2SFP.

version is KA.15.15.0006.

With CURL it works, the problem is from my contoler code.

Serge,

Can you obtain the following:

1) debug logging on the procurve switch

2) wireshark trace (of the communication between the switch and the controller) This can be run on the controller.

Debugging on the switch:

debug destination session

debug openflow errors

debug openflow events

debug openflow packets

And can do the captures (debug and wireshark) for 1) a good case (like with CURL) and 2) a broken case?

Regards,

Scott
