profile
An IPQoS profile name.
queue_id
0~the number of queues-1. For example, if a profile has 8 queues, then you can use
0~7.
pir
Peak Information Rate (PIR) is the maximum data rate allowed for the downstream
traffic flowing through the system.
Enter a number which is a multiple of 64 in the range of 128~131072 kbps.
cir
Committed Information Rate (CIR) is the guaranteed data rate for the downstream
traffic flowing through the system.
Enter a number which is a multiple of 64 in the range of 64~65536 kbps.
Note:
cir
<
pir
<= 2 x
cir
. For example, the
cir
is 1024, you should enter the
pir
equal or less than 2048 (=2 x 1024).
pbs
Peak Burst Size (PBS) is the maximum burst size allowed for the downstream traffic
flowing through the system when the burst data rate is between the predefined PIR
and CIR.
Enter a number which is a multiple of 256 in the range of 3072~65536 bytes.
cbs
Committed Burst Size (CBS) is the committed burst size allowed for the downstream
traffic flowing through the system when the burst data rate is smaller than the
predefined PIR.
Enter a number which is a multiple of 256 in the range of 3072~65536 bytes.
Note:
cbs
<=
pbs
level
Set the queue’s priority level 0~7. The larger the number, the higher the priority.
weight
You can configure different IPQoS profiles with queues that have the same queue
priority level. IPQoS then uses Weighted Round Robin (WRR) scheduling to service
these queues on a rotating basis based on their queue weight. Use these fields to set
the priority weight (1~127) of each queue in an IPQoS profile. The higher a queue’s
weight, the more service it gets.
