7.6.9.1 Scheduling
Mode
To select a packet scheduling mode, use the following command.
Command Mode
Description
qos scheduling-mode sp
{
PORTS
|
cpu
} [<0-7>]
Selects SP packet scheduling mode for ports or CPU.
sp: strict priority queuing
PORTS: port numbers
0-7: queue number
qos scheduling-mode
dwrr
{
group0
|
group1
} {
PORTS
|
cpu
}
[<0-7>]
Global
Selects DWRR packet scheduling mode for ports or
CPU.
dwrr: deficit weighted round robin
PORTS: port number (eg. 1,2, 1-10)
0-7: queue number
The default scheduling mode is
DWRR
. And it is possible to assign a different scheduling
mode to each port.
Additionally, switch assigns DWRR scheduling mode for a group. If you select DWRR
packet scheduling mode for one port as a group, all queues of this port are treated exter-
nally and internally by DWRR. However, if you select SP packet scheduling mode for one
port and make one group include several queues on DWRR packet scheduling mode, this
group implements as if it is one single queue. The scheduling mode of all queues is SP,
but a group including several queues operates in DWRR.
7.6.9.2 Weight
To set a weight for DWRR scheduling mode, use the following command.
Command Mode
Description
qos weight
{
PORTS |
cpu
} <0-7>
<1-255>
Sets a weight for each port and queue.
PORTS: port numbers
0-7: queue number
1-255: weight value (default: 6)
qos base weight
PORTS
<1-255>
Global
Sets a ratio among all queues according to configured
weight.
1-255: base weight value (default: 6)
7.6.9.3
Maximum and Minimum Bandwidth
To set a maximum bandwidth, use the following command.
Command Mode
Description
qos max-bandwidth
PORTS
<0-
7> {
BANDWIDTH
|
unlimited
}
Global
Sets a maximum bandwidth for each port and queue.
PORTS: port numbers
0-7: queue number
BANDWIDTH: bandwidth in the unit of MB
unlimited: unlimited bandwidth (default)
