In the third hybrid algorithm, 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, 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

Argument Description
<txq0-weight> ...
<txq4-weight>
Example
The following example configures hybrid-3 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-3 packets 10 10 20 20 40
device-name(config-if 1/1/4)#end
device-name#show qos scheduling 1/1/4

Configuring Hybrid-4 QoS Queue Handling
The qos scheduling hybrid-4 command, in Global Configuration or Interface Configuration
mode, is used to apply and configure the forth hybrid QoS algorithm.
In the forth hybrid algorithm, 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, 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.

scheduling
The weights assigned to the weighted transmit queues. The values must be
positive and add up to 10 or 100.
