Hi Yiannis, Thanks for your reply . sorry but didnt really understand here. I have a TP-Link AP and i connected my laptop to it, till here fine the port is added and it is shown to the controller. However if i disconnect the port from the AP , the OF protocol doesnt sends an Port Status notifications to the controller . I want to check if this is normal when using Pantou on OpenWRT. On the other hand using a mikrotik switch if i disconnect the client it sends the Port status notification to the controller.
Many thanks :) Etienne On 15 May 2013 19:58, Yiannis Yiakoumis <yiann...@stanford.edu> wrote: > Hi Etienne, > > You are not supposed to get a PORT_DOWN when you remove the cable, it's > when it's when "port is administratevely down".
