The maximum transmission band is set when the fixed band assures each queue
will transmit a packet. Table 1-79 shows the list of the parameters.

*1: The VAN line or the group set at four queues.
*2: The maximum error is about 2%.
*3: Set the maximum transmission band of a queue as described below when the queue traffic type is specified as
guarantee. Minimum guarantee band for each queue
limitation band of line
*4: The router operates under output priority control when the total number of guaranteed bands specified in each
queue exceeds the line rate. The guaranteed band specified in each queue is a maximum transmission band when
the traffic type is a fixed band. It is a minimum guarantee band when the traffic type is a variable band. The
unspecified queue is 80 kbps.
