| - | ratio: 19/6/1 = 26Mbit/s bandwidth. \\ | + | ratio: 19:6:1 = 26Mbit/s bandwidth. This is also the interface output limit. \\ |

| - | 2.Configure the desired Bandwidth congestion: \\ | + | 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. \\ | ||
