-peakTheratemaximum<kbps>transmission[ROUTE-OS6B]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.

*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.
