Configuring an Assured Rate for a Scheduler Node or Queue

You can configure the effective weight of the scheduler node or queue by configuring a static assured rate or a hierarchical assured rate (HAR). HAR dynamically adjusts the available bandwidth for a scheduler node based on the creation and deletion of other scheduler nodes.

By default, the HRR weight is configured for the scheduler profile. If the assured rate setting is other than none (the default), then the assured rate is used instead of the HRR weight setting for the scheduler node or queue.

Tasks to configure an assured rate are:

Configuring a Static Assured Rate

To configure a static assured rate:

  1. Create a scheduler profile.
    host1(config)#scheduler-profile static host1(config-scheduler-profile)#
  2. Specify a numeric rate with the assured-rate command in the scheduler profile.
    host1(config-scheduler-profile)#assured-rate 56000 host1(config-scheduler-profile)#assured-rate 50000 - 31000

    You can specify the static assured rate value in bits per second or kilobits per second. The range for the value is 25 Kbps to 10 Gbps. By default, no assured rate is configured.

    Note: You can configure an assured rate of more than 1 Gbps only in kilobits per second by using the kbps keyword.

    Use the operator and operandValue variables to configure an assured rate with an expression.

Configuring a Hierarchical Assured Rate

To specify that the HAR is used for scheduler nodes (HAR is not used for queues or ports):

  1. Create a scheduler profile.
    host1(config)#scheduler-profile har host1(config-scheduler-profile)#
  2. Specify the hierarchical keyword with the assured-rate command in the scheduler profile.
    host1(config-scheduler-profile)#assured-rate hierarchical

Changing the Assured Rate to an HRR Weight

To change an assured rate to an HRR weight:

  1. Create a scheduler profile.
    host1(config)#scheduler-profile static host1(config-scheduler-profile)#
  2. Delete the configured assured rate.
    host1(config-scheduler-profile)#no assured-rate

    The assured rate in the scheduler profile reverts to using the HRR weight specification.
