Command
Description
qos scheduling hybrid-2
Configures second hybrid-type scheduling.
qos scheduling hybrid-3
Configures from 3rd hybrid-type scheduling.
qos scheduling hybrid-4
Configures from 4th hybrid-type scheduling.
qos scheduling hybrid-5

Configuring Strict Priority QoS Queue Handling
The
qos scheduling sp
command, in Global Configuration mode, configures SP (Strict Priority)
scheduling.
By default, the SP scheduling is applied.
Command Syntax
device-name
(config)#
qos scheduling sp
Displaying QoS Scheduling Settings
The
show qos scheduling
command, in Privileged (Enable) mode, displays the current QoS
scheduling settings.
Command Syntax
device-name
#
show qos scheduling
Configuring Weighted Round-Robin QoS Queue Handling
The
qos scheduling wrr
command, in Global Configuration mode, applies and configures
Weighted Round-Robin (WRR) scheduling. In WRR scheduling, bandwidth is allocated
proportionally for each queue. Network resources are shared among all of the applications the user
services, each having the specific bandwidth requirements the user has identified.
By default, the SP scheduling is applied.
Command Syntax
device-name
(config)#
qos scheduling wrr

Argument Description
<
txq0-weight
>
…
<
txq7-weight
>
The weights assigned to the transmit queues. The eight values must be
positive and in the range <1-15>. A higher value means higher weight.
Example
The following example assigns weights 1, 1, 1, 1, 2, 2, 1, 1 to transmit queues txq0 to txq7
respectively on all ports. The
show qos scheduling
command displays the results on all ports.
