Problem with Network Protector

phoongsaan — Fri, 16 Jan 2015 08:41:52 GMT

Hello Guy, I follow the HP Network Protector SDN Administrator Guide v 1.1 .

All Configuration is the same as the example told us to do.

However, when I try to use network protector application I cannot connect the switch procurve 5406zl on the application but the switch can connect on VAN Controller.

When I see the support logs i found the error about "10.2.1.230 (Procurve 540lzl) not mapped to any region; no roles to sync" but I dont know what does it mean.

I use the VAN controller verion 2.2.5 with Network protector version 1.0 and the VAN controller version 2.4.5 with

Network Proctector 1.1 it have the same problem

additional: I use HP Procurve Switch 5406zl with module v2.0 and configured snmpv3 already.

am I doing something wrong?

thankyou

Hello,

If you used the wizard for the snmpv3 user creation on the 5406zl , try to delete it and create a new one via the CLI.

If this is not the case, please provide the switch "show tech all" output and the controller log.log

Hello phoongsaan,

Looking at the show tech all of the switch it seems that you have a problem between the switch and the controller:

W 01/16/15 10:20:47 03876 OPENFLOW: OpenFlow Instance sdn: TCP connection failed
while connecting to the controller with IP address 10.2.1.200.

They seem not able to communicate.

I think the controller is connected to port A3 and your test host is connected to port a 13.

I can't see snmpv3 entries in the log and I would like to ask you what follows:

1) did you configure the SNMPv3 user on Network Protector?

2) can you see the switch on the controller topology screen?

3) can you see the flow being added to the switch?

If the answer to question number 3 is yes, I can see dns queries being intercepted by the application but the product is not licensed.

My assumption is that you are testing the application using its Blacklist.

If I'm correct, are DNS queries sent to the controller correctly?

Hi SDN Team,

Similar kind of issue I am facing, the Controller device reads the device details but my application is not able to read the same.

I'm trying to fetch datapath info using Controller Service API and i have implemented logger to check the response. It is returning with empty data when logs are checked. Code snippet below

void startHandlingControllerEvents(ControllerService controllerService) {
controllerService.addDataPathListener(dataPathListener);

Set<DataPathInfo> dataPaths = controllerService.getAllDataPathInfo();
logger.info("Chethan:4.3 Inside startHandlingControllerEvents DataPath Info: ",dataPaths);

Any help will be appriaceted a lot,

Also note that my controller trial period is over, Will that have any problem,

Regards,

Chethan,
