[nox-dev] nox api support for openflow 1.0 spec operation

[Amit Tewari]

Hi,

 

I am currently using NOX 0.9.0(zaku)~full~beta  contrlooer for my
openvswitch 1.2.2 on openflow 1.0

 

I have developed certain api's using /lib/core.py file .

I am able to get table statictics and port statistics of switch on nox.

 

ISSUE:

1.  I want to extract per flow statistics , queue statistics on nox
. but I am unable to find api's and handlers for it.
2.  I want to support ENQUEUE action also, but when I use
send_flow_command  api it returns error.

a.  Self.ctxt.send_flow_command with action argument as
OFPAT_ENQUEUE  then make_actions_array routine returns error action not
supported

 

b.  In make_actions_array routine only testing is for
OFPAT_OUTPUT action type.

 

c.  Although lib/openflow.py contains all flags and
operations as per openflow 1.0 spec. 

 

Please let me know how I can meet support these features using nox, or I
need to use different nox version ?

 

Regards

Amit Tewari

Item #1:
flowtracer and monitoring both do per flow statistics.  You might want to 
examine how they do it (they use pylibopenflow to craft an OpenFlow message).

Item #2:
As I mentioned in response to your previous message, you must be using the 
destiny branch of NOX (not zaku) to use OFPAT_ENQUEUE.  Please upgrade.
