-1.Set the Administrative Status to enabled ​\\ +The ratio must not exceed 40:\\ 
-{{:​configuration:​qos_administration.png?600|}} \\ +If there is only traffic for one queue it may use the unused bandwidth of the other queues\\ 
-2.Configure ​the desired ​Bandwidth ​congestion: \\+Only the output can be configured. \\

 +**Bandwith: fixed (WWANX/​WAN/​OpenVPN) ** \\ 
 +{{:​configuration:​qos_fixed.png?1200|}} 
 +example: ​\\ 
 +high: TOS (Dec) 184 = DSCP (Dec), 46 (Hex) 0x2E / for voice application\\ 
 +low:  TOS (Dec) 104 = DSCP (Dec), 26 (Hex) 0x1A / for video application\\ 
 +default: All OTHER = not specified 
 + 
 +ratio: 19:6:1 = 26Mbit/s bandwidthThis is also the interface output limit. \\  
 +Because of this it is important to know the permanent throughput . \\ 
 +QoS is no longer working if the throughput falls under 26Mbit/​s ​ .\\ 
 + 
 +**Bandwidth: ​auto(WWANX) ​ ** \\ 
 +IP to ping: Configure a reachable host in the internet, preferably the target host. \\ 
 +Based on the RTT the bandwith ratio is divided as follows: \\ 
 +higest priority = 50%, \\  
 +middle priority = 45%, \\ 
 +lowest priority = 5% \\
  
-**Interface**:​ Select the desired inteface. \\ 
-**auto**: ​  Qos manages the bandwith according the configured priority.(1=high/​10=low). \\ 
-IP to ping: A host is needed in order to measure the current bandwith. \\ 
-**fixed**: ​ QoS works with the configured settings. The amount of bandwith should never be higher as the available bandwith. ​ \\
