3800 Switch issues

kobisamoray — Mon, 10 Mar 2014 16:15:44 GMT

Hi,

Writing an app which uses REST API, which HP controller, and a 3800 switch with SW KA.15.14.0003.

My OpenFlow instance uses OpenFlow 1.3.

I'm facing the following issue:
I pipeline traffic from table 100 to table 200, which work well, with the following flow spec:

I pipeline traffic with a different criteria from table 100 to table 201. HTTP transaction completes successfully, but the flow is not created.

Alternatively, I tried to use metadata to distinguish traffic on a single table (200) - in that case flow creation fails with the following error:
"error":"java.lang.IllegalArgumentException","message":"Unsupported set-field: METADATA"

Any advice?

Hi kobisamoray,

What is the controller version you are using?

If you are using version 2.0 then you can check supported flow_instruction at https://Controller_IP:PORT/sdn/v2.0/models

For version 2.0 it shows as below

"write_metadata": {

"description": "Setup the metadata field for use later in pipeline",
"$ref": "#/hex"

}

If you are using older version of controller , you can upgrade the same.

Thanks,

Hi,

I've upgraded to 2.0.

Will check now.

Thanks.

Hi,
I upgraded the controller as advised.
I face a new issue now:
After I've added a few flows via REST, I try to retrieve them.
Trying to access flows via REST, HTTP transaction fails with the following error:
"error":"java.lang.IllegalStateException","message":"Timed-out waiting for response"

Tracing the OpenFlow session between the switch and the controller with Wireshark, I see that the switch reply to flow stats request is immediate.

Anything that I should look for?

Hello kobisamoray,

Is the problem intermittent ?
Could you please share the exact JSON that you used for adding the flow?

Thanks,

Hi,

See my flow specifications in the attched flows_json.txt file.

In addition, I've seen the following error in /var/log/sdn/virgo/logs/virgo-server/log.log:

Some additional files:

log.txt: containing /var/log/sdn/virgo/logs/virgo-server/log.log output in a more readable manner

switch_output.log: The flow output on the HP 3800 switch

I tried to post a Wireshark capture with the OpenFlow exchange, between the switch and the controller, but I can't upload into the message board.

LMK if more info is required.
