Configuring ETS

Configuring ETS

ETS provides flexible, hierarchical scheduling management to prevent interference and conflicts between services after Ethernet and storage networks of a data center is converged.

Pre-configuration Tasks

Before configuring ETS, complete the following tasks:
  • Configuring a link layer protocol so that interfaces at both ends of a link are Up
  • Configuring Priority Mapping to map packet priorities to PHBs/colors
NOTE:

When the packet forwarding mode on the CX710 switch module 40GE converged switching plane is set to Cut Through, the CX710 switch module 40GE converged switching plane does not support ETS. To use ETS, run the assign forward mode store-and-forward command to change the packet forwarding mode to store-and-forward.

Configuring an ETS Profile

Context

ETS provides two-level flow control:
  • Flow control based on the priority group: congestion management and traffic shaping based on the priority group
  • Flow control based on the priority: queue congestion management, queue shaping, and queue congestion avoidance

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    dcb ets-profile profile-name

    An ETS profile is created and the ETS profile view is displayed.

    The system provides a default ETS profile default. This profile can be modified but cannot be deleted. You can create a new ETS profile or modify the default ETS profile according to service requirements.

  3. (Optional) Run:

    priority-group pg-value queue { start-queue [  to end-queue ] } &<1-8>

    The specified interface queues are added to a priority group.

    By default, queues 0, 1, 2, 4, and 5 belong to PG0, queue 3 belongs to PG1, and queues 6 and 7 belong to PG15.

  4. (Optional) Configure flow control based on the priority group.

    • Run:
      priority-group pg-value drr weight weight-value

      The Deficit Round Robin (DRR) weight of a priority group is set.

      By default, the weights of PG0 and PG1 are both 50.

      NOTE:
      • If you set the DRR weight of a priority group (PG0 or PG1) to weight, the system sets the DRR weight of another priority group to 100–weight.

      • When there are more than three priority groups, number of queues in only one priority group can be more than one.

    • Run:
      priority-group pg-value shaping cir cir-value pir pir-value [ cbs cbs-value pbs pbs-value ]

      Traffic shaping is enabled for a priority group and shaping parameters are set.

      By default, traffic shaping is disabled for a priority group.

  5. (Optional) Configure flow control based on the priority.

    • Run:
      queue { start-queue [ to end-queue ] } &<1-8> { pq | drr  [ weight weight-value ] }

      A scheduling mode is set for interface queues.

      By default, an interface queue uses priority queuing (PQ).

    • Run:
      queue { start-queue [ to end- queue ] } &<1-8> shaping cir cir-value pir pir-value [ cbs cbs-value pbs pbs-value ]

      Traffic shaping is enabled for interface queues and shaping parameters are set.

      By default, traffic shaping is disabled for an interface queue.

    • Run:
      queue { start-queue [ to end- queue ] } &<1-8> wred drop-profile-name

      A drop profile is bound to interface queues.

      By default, no drop profile is bound to an interface queue.

  6. Run:

    commit

    The configuration is committed.

Applying an ETS Profile

Context

You can apply an ETS profile to an interface so that the interface can provide differentiated services.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The interface view is displayed.

  3. Run:

    dcb ets enable profile-name

    An ETS profile is applied to the interface.

  4. Run:

    commit

    The configuration is committed.

Checking the Configuration

Prerequisites

All the ETS configurations are complete.

Procedure

  • Run the display dcb ets-profile [ profile-name ] command to check the ETS profile configuration.
  • Run the display dcb [ interface interface-type interface-number ] command to check the DCB configuration and negotiation status.
