Configuring Hybrid-6 QoS Queue Handling
The qos scheduling hybrid-6 command, in Global Configuration or Interface Configuration
mode, is used to apply and configure the sixth hybrid QoS algorithm.
In the sixth hybrid algorithm, txq2, txq3, txq4, txq5, txq6 and txq7 are set to behave according
to strict priority scheduling, and the rest of the queues behave according to Weighted Round
Robin (WRR). According to this configuration:
•
tqx7 is serviced as long as it has packets for transmission.
•
When txq7 is empty, txq6 is serviced as long as it has packets.
•
When txq6 is empty, txq5 is serviced as long as it has packets.
•
When txq5 is empty, txq4 is serviced as long as it has packets.
•
When txq4 is empty, txq3 is serviced as long as it has packets.
•
When txq4 is empty, txq2 is serviced as long as it has packets.
•
When txq2, txq3, txq4, txq5, txq6 and txq7 are empty, the rest of the queues are
serviced according to their assigned weights.
By default, the SP scheduling is applied.
Command Syntax
device-name(config)#qos scheduling hybrid-4 <txq0-weight> <txq1-weight> <txq1-weight>
Argument Description
<txq0-weight> ...
<txq1-weight>
Example
The following example configures hybrid-6 scheduling on port 1/1/4. The show qos
scheduling command displays the results on the specified port.
device-name(config-if 1/1/4)#qos scheduling hybrid-6 packets 40 60
device-name(config-if 1/1/4)#end
device-name#show qos scheduling 1/1/4

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 {UU/SS/PP | all}
Argument Description
UU/SS/PP Display the scheduling settings for the specified interface.
all Display the scheduling settings for all the interfaces.
