[-priority <No.>] [-discard <No.>]
Makes the flow control function effective by specifying the output priority and
queuing priority. Sets the priority in <No.>. The priority parameter is used as the
output priority in the case of output priority control and as the queue number in
the case of minimum band assurance. If the output line is an ATM line, it sets
the value of the cell loss priority indication (CLP bit) of the cells transmitting in
VC using either the "output" priority or the "queuing" priority. To set the cell loss
indication bit, refer to the parameters defined in the
GR2000 Configuration
Commands, (universal CLI) Vol. 1
, vc (VC information)." If the VC’s service
category is GRR or GFR2, select the "queuing" priority from the VC priority
queue. If the VC’s service category is GFR2, set the output priority from the VC
priority queue. For the queuing and output priority of VC priority queuing, refer
to the
GR2000 Applications Guide
. When setting this parameter, it is not possible
to set -replace_dscp, or -class_dscp.
Default:
-priority: 4
-discard: 4
Range of value:
-priority <No.>: 1 to 1000
(Incase of the output priority control, the greater the value of
the output priority, the more preferentially the packet is
issued.)
-discard <No.>: 1 to 4.
(The smaller the value of the queuing priority, the more
preferentially the packet is discarded.)
The ranges for the output priority (priority) and the queuing priority(discard)vary
depending on the setting conditions.
[-group<No.>][ROUTE-OS6B]
Designates the group number to be outputted when the output line transmission
control is the group band control relative to the Line. Setting is possible only
when the group number has been previously set in the QoS interface

*1:
If value outside the range is set in output priority, the setting contents are nullified.
*2:
If the QoS attribute of the output interface is the minimum band assurance (specified by
kbit/s), the flow control is executed as follows:
•
Queuing priority 1 and 2: Flow control is executed at queuing priority 2.
•
Queuing priority 3 and 4: Flow control is executed at queuing priority 4.
