Example Implementations using QoS and QoS
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
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
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
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
