So if you disable the timeouts, a flow should remain in the table until it's removed or until the switch is reset. Is that not working somehow?
Secondly, why don't you just reinstall these flows from the controller? I think I must be missing something. -- Murphy On Jul 13, 2012, at 5:27 AM, Anthony Salim wrote: > Hi Murphy, > > Hmm the case is to have a cache storage of all the flows table because as we > know, the switches only can keep flows for certain amount of time but once > the timer expired, it will just disappear.
