-peak_rate <kbps> [ROUTE-OS6B]
The maximum transmission band is set to the VLAN line or the group.
Default:
None
Range of value:
The value setting range varies by each line type.
Table 1-78 shows the range in which a line’s maximum
transmission range can be set.
-traffic <Queue No.> -constant -peak_rate <kbps> [ROUTE-OS6B]
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.

Excess band
allocation ratio.
-weight
1 to 63
Distribute and allocate the
bands according to the
ratio in which the excess
band is set by queues.
*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
≤
Maximum transmission band for each queue
≤
Maximum
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.
