- | 1.Set the Administrative Status to enabled \\ | + | The ratio must not exceed 40:1 \\ |
- | {{: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) ** \\ | ||

+ | 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 bandwidth. This 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. Only the upstream can be configured. \\ | ||
