Hi, We are doing the implementation with FreeRadius+mysql+mikrotik. for a starter plan we have 30G usage limit @4mbps(d)/4mbps(u). After this limit, we need to scale down the speed to @2mbps(d)/2mbps(u). I have configured Mikrotik-Rate-Limit = '4096k/4096k' Is it mandatory to give the burst rates and burst time? Does it really help? And once the 30G is reached I need to send Mikrotik-Xmit-Limit Mikrotik-Recv-Limit In a pre-auth condition right? But I am confused with the following: Mikrotik-Recv-Limit-Gigawords Mikrotik-Xmit-Limit-Gigawords I read about it. But I'm not getting the thing 32 bit and 64 bit. Maximum 4G limit we can give? Can someone help me on this. -- Best Regards, Randeep Mob: +919447831699[kerala] Mob: +919880050349[B'lore] http://twitter.com/Randeeppr http://in.linkedin.com/in/randeeppr [image: --] Randeep Raman [image: http://]about.me/Randeeppr <http://about.me/Randeeppr>
