Quality of Service: Managing Bandwidth More Effectively
QoS Queue Configuration
Configuring the Number of Priority Queues
To change the number of outbound priority queues for all ports on the switch,
use the qos queue-config command.
Caution The qos queue-config command executes a write memory followed by an
immediate reboot, replacing the Startup configuration with the contents of
the current Running configuration. In addition to setting the number of
outbound port queues, the new configuration will remove any previously
configured bandwidth-min output settings.
Example. To change the number of outbound priority queues for all ports on
the switch from eight queues (the default) to four:
1. Configure the number of outbound priority queues by using the qos queue-
config command.
HP Switch(config)# qos queue-config 4-queues
A caution message is displayed (see the Caution note above) concluding
with the following prompt.
Do you wish to proceed? [Proceed/Cancel]
2. Type Proceed to continue.
A second confirmation prompt appears:
Please confirm reset. [Yes/Cancel]
3. Type Yes to initiate a write memory followed by an immediate reboot. (If
you enter Cancel at either of the two prompts, the command is aborted
and the current queue configuration is maintained on the switch).
The changes will be committed to the startup configuration and the switch
will reboot automatically with the new priority queue changes in effect.
See Table 5-14 on page 5-98 for a listing of the default GMB percentages
that are allocated per queue.
