Hello,
Sometimes when I try to execute the following curl on the controler to obtain flow table of a swith:
curl --noproxy 130.223.16.128 --header 'X-Auth-Token: a33de0c8553448aaaeec77d1d7934f6b' --fail -ksSfL --request GET --url https://130.223.16.128:8443/sdn/v2.0/of/datapaths/00:14:f0:92:1c:21:fa:c0/flows
curl: (22) The requested URL returned error: 500 Internal Server Error
I have the previous error.
Sometimes it works.
If I look for the log.log file, it have the following entry:
2014-03-26 11:20:06.642] WARN of-io-34-thread-4 hp.of.msglib DE0005I Parse FAILED: hdr=[V_1_3,MULTIPART_REPLY,1280,110638], bytes=[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]

Re: Problem with Interface RESTful when trying to obtain "flow table" on a switch
Hello sbotkine,
Thanks for your query.
We are working on your problem.
Meanwhile we would like to know if you get the same error when you try REST API to see the flows.
Please try REST API Datapaths/{dpid}/flows [from HP VAN SDN Controller REST API doc- page 60] and let us know if you still face
the same error.
Thanks,
HP SDN Team

Re: Problem with Interface RESTful when trying to obtain "flow table" on a switch
Hello,
Yes I reproduce the problem on the RSdoc interface:
Request URL:
https://130.223.16.128:8443/sdn/v2.0/of/datapaths/00%3A14%3Af0%3A92%3A1c%3A21%3Afa%3Ac0/flows
Response Body:
{
"error": "java.lang.IllegalStateException",
"message": "Timed-out waiting for response"
}
Response Body:
500
Response Header:
Date: Mon, 31 Mar 2014 06:09:12 GMT Server: Apache-Coyote/1.1 X-FRAME-OPTIONS: deny Access-Control-Allow-Methods: GET, POST, PUT, HEAD, PATCH Content-Type: application/json Access-Control-Allow-Origin: * Transfer-Encoding: Identity Connection: close Access-Control-Allow-Headers: Content-Type, Accept, X-Auth-Token
Notice that the problem occurs especially after the insertion of some Flow_mod in the switch, but not every time.

Re: Problem with Interface RESTful when trying to obtain "flow table" on a switch
Hello Sbotkine,
The issue you mentioned was a known issue that was affecting HP VAN SDN Controller Release 2.0 operations .This has been fixed with our new Firmware release K/KA/WB.15.15.0006. (For 3800, the KA version must be used). The Web released software can be accessed from this link www.hp.com/networking/support
Enter a product # or description – e.g 5406” check the box for the 5406
Click on “display selected”
Click on the link “software downloads”->It will take you to:
https://h10145.www1.hp.com/downloads/SoftwareReleases.aspx?ProductNumber=J9642A
Sign in with a passport account to dowload the software( specifically that mentions "Early Avaialbility")
EA – Early Availability – should be evaluated prior to moving it to a production environment
GA – General Availability – considered production ready.
Please download the firmware and keep us posted on the status.
Thanks
Sudha.
