Quality of Service (QoS): Managing Bandwidth More Effectively QoS Queue Configuration QoS Queue Configuration In earlier releases, QoS queue configuration was limited to changing the number of outbound queues per port that all switch ports use to buffer packets for 802.1p user priorities. Beginning with software release Z.14.21 or later, it is also possible to modify the 802.1p priority to queue mapping. By default, there are four priority queues or traffic classes configured per outbound port. You can configure the switch to a different number of queues in order to adjust the available bandwidth per queue. Use the following commands to change the number of queues per port and display the current priority queue configuration on the switch. Syntax: qos queue-config < 2-queues | 4-queues | 8 queues > Configures the number of outbound priority queues for all ports on the switch using one of the following options: 2-queues, 4-queues, or 8 queues. (Default: 4 queues) Caution: This command will execute a "write memory" followed by an immediate reboot, replacing the Startup configuration with the content of the current Running configuration. The new configuration will: 1. Remove any previously configured "bandwidth-min output" settings. 2. Remove any previously configured traffic templates. 3. Set the new number of outbound port queues. If you select anything but "yes" for this operation, the operation is aborted and a message stating "Operation aborted" appears. show qos queue config Displays the current qos queue configuration. 5-63
