The combination of MIN and MAX Bandwidth QoS combined with QoS Prioity allows for multiple levels of QoS implementation. We recommend that QoS is configured using one of the following formats:
PRIORITY with MAX BW – All routes are configured with the default value of 0 for MIN and can have a MAX BW defined to limit the amount of BW used by a route. Routes are designated as Priority 1 or 2.
Note: This is would be used when wanting to prevent the Priority 1 traffic from using all of the BW. Priority 2 traffic could also be limited to a maximum BW usage.
MIN/MAX BW Only – All routes are designated as Priority 1 default. Routes are configured with defined values of MIN BW. The MIN BW determines by the amount of BW that you want to dedicate to a route. The MAX is automaticaly calculated by the CiM based upon the formula listed in section 11.2.3.1 NOTES on QoS and QoS Prioritization: Step 2.
Note: This would be used for all traffic to be forwarded on a “first come, first served “ basis, using strict BW quaruantees and limits.
MIN/MAX with Priority – Routes are designated as Priority 1 or 2. MIN BW’s are defined for each route and MAX BW’s are calculated by the CiM based upon the formula listed in NOTES on QoS and QoS Prioritization: Step 2.
Note: This is similar to PRIORITY with MAX BW with the additional capability of varying MIN BW’s for routes. This should only be used when there are different MIN BW requirements for routes within the same Priority.
Here is a screen capture of the CiM CLI using the MIN/MAX with Priority format to configure QoS for various traffic routes. The CiM modem data rate is 2048 kbps for this example :
