MIN/MAX BIN 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 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 onlybe used when there are different MIN BW requirements
for routes within the same Priority.
Below is an example 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

Route 1 (Vidconf) and Route 2 (Vol P) traffic require that the packets are
forwarded with the least amount of latency, so they are designated as Priority 1.
Route 1 has a Min B/W of 512 kbps to insure that amount of B/W will always be
available for the video traffic. Route 2 is set up similarly with a Min B/W of 384
kbps for VoIP traffic.
Note: Setting a Min B/W for a route does not mean that that B/W is only available for that
particular route 100% of the time. If less than the Min B/W is being used for a route, the
CiM will allow other traffic to use the B/W; so maximum BW usage is always achieved. A
Min B/W is set to make that amount of B/W available whenever needed for that route.
