[nox-dev] NOX API development
Hi, I am using NOX as a controller for my openvswitch 1.2.2 with openflow 1.0 . I have created api for adding flow and deleting flow from controller. I have used lib/core.py api's install_datapath_flow and delete_datapath_flow. But core.py do not have api or command for modifying flow table rules and obtaining switch flow table statistics. If I use openflow.OFPFC_MODIFY flag in send_flow_command, it gives me error-invalid action type Also if I give flag as OFPAT_ENQUEUE it gives me error. I wanted to know Are there any other library files in nox whose functions I can use for developing my api or nox dosent support it ?

Also if I give flag as OFPAT_ENQUEUE it gives me error. Where are you trying to put that? It belongs in the actions list. Also, it is one of the newer actions and it won't be available on older versions of NOX. Are you using the destiny branch? I wanted to know Are there any other library files in nox whose functions I can use for developing my api or nox dosent support it ? send_openflow_command() pretty much sends a raw buffer to a datapath, so you can craft pretty much any OpenFlow command you want (often using pyopenflow.py), and send it. The monitoring component uses this technique, so you can look at it as an example. Among other things, it uses it to get flow stats. Hope that helps.
