I have a problem with A5500 EI, because it returns support for VLAN_VID field in OFPMP_TABLE_FEATURES reply. Nevertheless, it doesn't accept FLOW_MOD wherein included is VLAN_VID. 

 

FLOW_MOD:

 

ofm:[V_1_3,FLOW_MOD,72,188715],cmd=ADD,match={Match(V_1_3):[type=OXM,len=10],fields=VLAN_VID},...}

    {Oxm:V_1_3:[cls=0x8000(OPENFLOW_BASIC),ft=6(VLAN_VID),hm=false,len=2],vlan-id=5}
  Instructions:
    {Instr:V_1_3:[type=APPLY_ACTIONS,len=8],actList=(none)

 

And MessageFuture:

 

MsgFuture:xid=188717,OFM_ERROR,reply={ofm:[V_1_3,ERROR,76,188717],BAD_MATCH/BAD_TAG,#dataBytes=64,OFM-cause:[V_1_3,FLOW_MOD,72,188717]}

 

HP SDN Controller 2.5.15, HP A5500-48G-PoE+ EI(Comware 5.20.99, Release 2221P15)


Does anyone know what could be cause of this?

SetField actions are not being applied to PacketOut messages

September 7, 2015, 11:00 am

Hello,

 

I'm currently running the HP SDN VAN controller v2.5.15.1175 connected to an HP 3800 switch with two VLANs, one for the openflow traffic and another one for the controller. Both VLANs are, however, connected to each other. Both are using Openflow 1.3.

 

The software we're currently developing consist on the following:

  • One flow which captures ARP traffic directed to a non-used IP address (let's say 10.250, for example), and sends it to the controller. There, the controller forges an ARP reply packet with a random MAC Adress and routes it to the input port.
  • One flow which captures IP traffic directed to the same IP address mentioned above, 10.250, and sends it to the controller. There, the controller grabs a MAC-IP pair from a config file (say, 10.11 and aa:bb:cc:dd:ee:ff), both belonging to a machine up & running and connected to the openflow VLAN, and creates another flow which redirects all traffic directed to 10.250 from the src ip of the captured packet to this machine (say, 10.2). Then, it applies this actions to the packet and calls send() on it.
    Also, a flow for the reverse translation is also created (capture packets from 10.11 directed to 10.2 and change the source address to 10.250.
    All these flows have their output action set to Port.FLOOD, as well the output action of the packetOut sent by the controller.

With this setup, I'm basically executing an IP forwarding, changing 10.250 by 10.11.

 

However, this works only for the second and following packets, the first one (which was captured by the controller and then altered) is not changed in anyway (checked it with a machine running wireshark on the same VLAN).

 

I've double and triple checked the documentation, and afaik this SHOULD work, but it does not.

 

I'm pretty clueless here, to be honest. Any help would be greatly appreciated.

 

Here are the key parts of the code I'm running: http://pastebin.com/1cZkGkPc

 

Best regards, Roberto.

Can i use Network Protector for Open vSwitch?

Dear All,

 

 

I want to test HP VAN SDN Controller and HP Network Protector with the Open vSwitch...  I have found example, for the Open vSwitch and VAN Controller integration but can't find for Network Protector.

 

 

How do i use Network Protector environments for the Open vSwitch?  ( we don't have OpenFlow enabled Physical Switches )

 

 

I implemented VAN Controller and Network Protector separate Ubuntu Servers and successfully it.

 

 

I will install two ubuntu server with KVM option and use Open vSwitch for networking..  After the installation i will integrate SDN platform if we can!

 

 

Best Regards

SDN Network Protector; user points to remote IP host instead

Hi,

 

As I saw in the HP SDN Network Protector info, it would get DNS traffic by using OpenFlow switch. OpenFlow switch like 2920 can send a user entering a web site(DNS info) to Protector and examines it.

 

If some smart users enter a remote malicious website by using IP address instead, does Network Protector still examine for those users for that site?   

 

 

 

Thanks,

S. Lee.

Hi,

We are looking at the idea of enabling openflow to a HP Van controller on one of our vlans

We see alot of internet scanning activity on that vlan we want to block/quarantine once a theshold is hit or even throttle if possible ?

We use 2x HP 5900AF-48XG-4QSFP+ in an IRF stack, running Comware 7.1.045 2311P01 currently

Do you think HP Van and this network protector sdn app would be possible solution to our problem ?

Network protector details:

HP Van Network Protector SDN APP

You can see from the below, we are trying to stop the below which we can see via current sflow reporting

Each color in the bars is a single src IP address on our side, the hight of the bars in the uniq destination IP's on the specific tcp ports, so this shows scanning on VNC ports and https

Hi, I am using Open vSwitch 2.4.0 and HP SDN VAN Controller 2.4.5. I can see the datapath of the virtual switch in the OpenFlow Monitor section in UI. Once I select the virtual switche's datapath, I am not seeing the manufacturer details of the switch. When I am navigating through the ports , flows and groups I am getting 'Waiting time out response' error and nothing is showing there. I noticed that the controller is fetching details of upto 150 tables only rom the swicth. Can anyone help me in this ? Why is it not showing any manufacturer details, port detail, flows and groups of the switch, eventhough it discovers the switch and shows it in topology ?

OpenFlow Multipart messages are not used by HP VAN SDN Controller

March 3, 2016, 8:05 am

Hi,

I'm using the HP VAN SDN Ctrl with a OpenFlow switches in a simulation software - somewhat similar to mininet.

I have installed version 2.6.11 of the controller and it seems to be operational. However, when I connect OpenFlow 1.3 capable switches to the controller, only the HELLO and FEATURES_REPLY messages seem to be taken into account by the controller. This is my assumption because information from Multipart reply messages (OFPMP_DESC and OFPMP_PORT_DESC) is never reflected in the controller.

I have attached screenshots and a Wireshark packet capture (rename HP_VAN_Capture.txt to HP_VAN_Capture.pcap) showing the packet exchanges, and missing information in the controller. For this reason, I believe the controller is not able to send flow modification messages and BDDP for topology discovery to the switches.

 Additional information: Interfacing the same switches with OpenDaylight controller works fine including adding flow entries so that the controller influences traffic forwarding the switches. Hence there seems to be something we are missing that is causing problems when we use the HP controller. 

Any information is appreciated.

Thanks!

Downloaded and succesfully installed HP VAN SDN Controller 2.6.11.0469 with local keystone on a Virtual Box VM with Ubuntu 14.04 TLS but when is try to Web to "https://ip address:8443/sdn/ui" it returne an error "HTTP status 404 not found. Tried with VM using NAT and Bridge Adapter. I have been focues on using the Bridge Adapter which fails when using local IP 127.0.0.1 and Real IP address (bridge adapter)

I  stepped through the troubelshooting guide and confirmed SDNC status, listening on 8443, proxy setting etc. I have tried with Chrome and Firefox (linux version) within the VM Guest OS as well as IE and Chrome on my host machine (Windows 7). All initially error due to certificate which I install into my certificate store both (host and Guest OS). I have also done a reinstall from scratch to ensure i hadn't missed a step but failed

Can anyone suggest what else to try or how to troubleshoot this. BTW i have looked at all the error logs etc in the intall and troubleshooting docs for 2.6 and all look good. I did look at my tomcat7 logs and only see the error 404 messages.

VAN: Installing a module with an additional JAR dependency

Hi all,

I am working on a VAN module which depends on the OkHttp Java library. I have added the library as a dependency in the pom.xml file for my business logic project, and my project compiles just fine. However, when I try to deploy the application on VAN, I get the following error:

Server Error – 500: Internal Server Error
URL: rs/apps/com.netlab.webhooks/install
View ID: apps
Type: error

The only thing I can think is that VAN (running on an Ubuntu machine) does not have the OkHttp library installed. What is the best course of action here? Should I try to package the library with my project or install OkHttp on the Ubuntu machine? Regardless, how do I go about this?

Thanks!
