4.18.4 QoS Port Scheduler Configuration

The QoS Egress Port Scheduler page provides an overview of QoS Egress Port Schedulers for all switch ports.

Figure 4-75. QoS Egress Port Scheduler

The QoS Egress Port Scheduler page has the following parameters:

  • Port: The logical port for the settings contained in the same row. Click on the port number to configure the schedulers.
  • Mode: Shows the scheduling mode for this port
  • Qn: Shows the weight for this queue and port

Selecting port number opens the following web page that allows you to configure the Scheduler and Shapers for a specific port.

  • Scheduler Mode: Controls how many of the queues are scheduled as strict and how many are scheduled as weighted on this switch port
  • Queue Shaper Enable: Controls whether the queue shaper is enabled for this queue on this switch port
  • Queue Shaper Rate: Controls the rate for the queue shaper. This value is restricted to 100-3281943 when the unit is kbps, and 1–3281 when the unit is Mbps. The rate is internally rounded up to the nearest value supported by the queue shaper.
  • Queue Shaper Unit: Controls the unit of measure for the queue shaper rate as kbps or Mbps
  • Queue Shaper Rate-Type: The rate type of the queue shaper. The allowed values are:
    • Line: Specifies that this shaper operates online rate
    • Data: Specifies that this shaper operates on data rate
  • Queue Shaper Excess: Controls whether the queue is allowed to use excess bandwidth
  • Queue Shaper Credit: Controls whether the queue has credit-based shaper enabled
  • Queue Scheduler Preemption: Controls whether the queue has frame preemption enabled
  • Queue Scheduler Weight: Controls the weight for this queue. This value is restricted to 1–100. This parameter is only shown if Scheduler Mode is set to Weighted.
  • Queue Scheduler Percent: Shows the weight in percent for this queue. This parameter is only shown if the Scheduler Mode is set to Weighted.
  • Port Shaper Enable: Controls whether the port shaper is enabled for this switch port
  • Port Shaper Rate: Controls the rate for the port shaper. This value is restricted to 100–3281943 when the unit is kbps, and 1–3281 when unit is Mbps. The rate is internally rounded up to the nearest value supported by the port shaper.
  • Port Shaper Unit: Controls the unit of measure for the port shaper rate as kbps or Mbps
  • Port Shaper Rate-Type: The rate type of the port shaper. The allowed values are:
    • Line: Specifies that this shaper operates on line rate
    • Data: Specifies that this shaper operates on data rate
