Precautions
1. When changing a queue mode, perform new setting after deleting the related
parameters.
2. The active attribute list on the QoS interface cannot be deleted.
3. WhenallocatesQoSqueueattributewith-bandwidth_kbpsqueuemodeto
interface by
qos-interface command, the maximum number of usable queue is
4000 per RP. Set the total queue count dedicated to each interface to be 4000 or
less per RP according to the below. The queue count dedicated to one interface
becomes the following by the setting of max_queue_number_N of allocated QoS
queue attribute information.
-max_queue_number_8 ---------- 250
-max_queue_number_16 ---------- 250
-max_queue_number_32 ---------- 250
-max_queue_number_250 ---------- 250
-max_queue_number_1000 ---------- 1000
For example, the interface using QoS queue attribute of minimum bandwidth
(kbit/s) that specified -max_queue_number_8, -max_queue_number_16,
-max_queue_number_32, or -max_queue_number_250 can be set up to 16 lines
per RP. The interface using QoS queue attribute of minimum bandwidth (kbit/s)
that specified -max_queue_number 1000 can be set up to 4 lines per RP. When
total queue count to be dedicated by QoS queue attribute of minimum bandwidth
(kbit/s) exceeds 4000 per RP, minimum bandwidth guarantee (kbit/s) cannot be
processed in the part of interface within the target RP.
4. The storage conditions on the performance and loading memory are provided
when using a QoS queue attribute list. Refer to the GR2000 Installation Guide.
5. With the interface having set the queue mode to -bandwidth_kbps (minimum
band assurance (specified by kbit/s)) and -bandwidth_traddic (band control
(specified traffic)) by using this command, the minimum band assurance (kbit/s
specified) and -bandwidth_traddic (band control (specified traffic)) function can
be executed only when the output priority is decided by output priority
specification using the flow control. If the output priority has been decided by
DSCP value by using the flow control, the minimum band assurance (kbit/s
specified) and -bandwidth_traddic (band control (specified traffic)) function
cannot be executed. Table 1-74 shows the relationship between the minimum
band assurance (kbit/s specified) and -bandwidth_traddic (band control
(specified traffic)), and the flow control.
6. This command cannot be set when a -cops parameter is set to qos (QoS
information).
7. If this command is inputted in the cases where changes are made on the IP
routing protocol information, the IP multicast protocol information, and the
MPLS information, and the
apply command is not being executed, the apply
subcommand is executed before the command is executed, and the changed IP
