srr-queue bandwidth shape Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands srr-queue bandwidth shape Use the srr-queue bandwidth shape interface configuration command to assign the shaped weights and to enable bandwidth shaping on the four egress queues mapped to a port. Use the no form of this command to return to the default setting. srr-queue bandwidth shape weight1 weight2 weight3 weight4 no srr-queue bandwidth shape Syntax Description weight1 weight2 weight3 weight4 Specify the weights to specify the percentage of the port that is shaped. The inverse ratio (1/weight) specifies the shaping bandwidth for this queue. Separate each value with a space. The range is 0 to 65535. Defaults Weight1 is set to 25. Weight2, weight3, and weight4 are set to 0, and these queues are in shared mode. Command Modes Interface configuration Command History Release 12.2(25)SEF Modification This command was introduced. Usage Guidelines In shaped mode, the queues are guaranteed a percentage of the bandwidth, and they are rate-limited to that amount. Shaped traffic does not use more than the allocated bandwidth even if the link is idle. Use shaping to smooth bursty traffic or to provide a smoother output over time. The shaped mode overrides the shared mode. If you configure a shaped queue weight to 0 by using the srr-queue bandwidth shape interface configuration command, this queue participates in shared mode. The weight specified with the srr-queue bandwidth shape command is ignored, and the weights specified with the srr-queue bandwidth share interface configuration command for a queue come into effect. When configuring queues for the same port for both shaping and sharing, make sure that you configure the lowest numbered queue for shaping. Note The egress queue default settings are suitable for most situations. You should change them only when you have a thorough understanding of the egress queues and if these settings do not meet your QoS solution. 2-484 Cisco Catalyst Blade Switch for HP Command Reference OL-8916-01
