The standard mac_learning application works fine. I think there's something related to the use of barrier request before installing the flows. We might be triggering it in our code somewhere.\r\n\r\nI'm not really proficient with pyretic, has anyone ever had problems with barrier requests before?\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/frenetic-lang/pyretic/issues/comments/70530165","html_url":"https://github.com/frenetic-lang/pyretic/issues/40#issuecomment-70530165","issue_url":"https://api.github.com/repos/frenetic-lang/pyretic/issues/40","id":70530165,"user":{"login":"AghOmid","id":2366023,"avatar_url":"https://avatars.githubusercontent.com/u/2366023?v=3","gravatar_id":"","url":"https://api.github.com/users/AghOmid","html_url":"https://github.com/AghOmid","followers_url":"https://api.github.com/users/AghOmid/followers","following_url":"https://api.github.com/users/AghOmid/following{/other_user}","gists_url":"https://api.github.com/users/AghOmid/gists{/gist_id}","starred_url":"https://api.github.com/users/AghOmid/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/AghOmid/subscriptions","organizations_url":"https://api.github.com/users/AghOmid/orgs","repos_url":"https://api.github.com/users/AghOmid/repos","events_url":"https://api.github.com/users/AghOmid/events{/privacy}","received_events_url":"https://api.github.com/users/AghOmid/received_events","type":"User","site_admin":false},"created_at":"2015-01-19T17:25:21Z","updated_at":"2015-01-19T17:25:21Z","body":"Flavio,\n\nYou can see the list of OpenFlow actions that Pyretic uses in the\nof_client/pox_client.py\n<https://github.com/frenetic-lang/pyretic/blob/master/of_client/pox_client.py#L100-L143>,\nfrom line 100 to 140.\n\nOn Mon, Jan 19, 2015 at 9:18 AM, Flavio Castro <notifications@github.com>\nwrote:\n\n> The weird thing is that the mac_learning module works fine.\n>\n> My first guess was that the sdx application was injecting an OpenFlow\n> error somewhere.
