Queue Scheduling and Traffic Shaping Management

Queue Scheduling and Traffic Shaping Management

This section describes the configuration model of queue scheduling and traffic shaping management and provides examples of XML packets.

Data Model

The configuration model file matching queue scheduling and traffic shaping management is huawei-qos.yang.

Only the X6H series cards on the S12700E support the /huawei-qos:qos/wlan/ap-shaping object.

Table 2-425 Queue scheduling and traffic shaping management

Object

Description

Value

Remarks

/huawei-qos:qos/traffic-queuing/queue-profiles/queue-profile/name

Indicates the name of a queue scheduling profile.

The value is a string of case-insensitive characters without spaces.

N/A

/huawei-qos:qos/traffic-queuing/queue-profiles/queue-profile/id

Indicates the queue index.

The value is an integer in the range from 0 to 7.

Eight queues must be configured simultaneously.

/huawei-qos:qos/traffic-queuing/queue-profiles/queue-profile/queue/schedule/schedule-mode

Indicates the queue scheduling mode.

Enumerated value. The values are as follows:

  • strict-priority-queuing: PQ scheduling

  • deficit-round-robin-queuing: WDRR scheduling

  • weight-round-robin-queuing: WRR scheduling

The X series cards do not support weight-round-robin-queuing.

/huawei-qos:qos/traffic-queuing/queue-profiles/queue-profile/queue/schedule/weight

Indicates the weight of a queue that participates in WRR or WDRR scheduling.
The value is an integer. The value range is as follows:
  • EE cards of the E series: 0 to 63
  • Other cards of the E series: 0 to 100
  • Cards of other series: 0 to 100

N/A

/huawei-qos:qos/traffic-queuing/queue-profiles/queue-profile/queue/shaping-ext/cir

Indicates the CIR for queue shaping.

The value is an integer, in kbit/s. The value range differs depending on the interface type:

  • Port group: 0 to 10000000
  • Other interfaces: 0 to X, where X indicates the maximum rate supported by the interface

The unit is kbit/s. The default value is the maximum bandwidth of an interface.

N/A

/huawei-qos:qos/traffic-queuing/queue-profiles/queue-profile/queue/shaping-ext/pir

Specifies the peak information rate (PIR) of a queue.

The value is an integer, in kbit/s. The value range differs depending on the interface type:

  • Port group: 0 to 10000000
  • Other interfaces: 0 to X, where X indicates the maximum rate supported by the interface

The unit is kbit/s. The default value is the maximum bandwidth of an interface.

The PIR must be greater than or equal to the CIR for queue shaping. By default, the PIR is equal to the CIR for queue shaping.

/huawei-qos:qos/traffic-queuing/queue-profiles/queue-profile/queue/shaping-ext/cbs

Indicates the CBS for queue shaping.

The value is an integer in the range from 10000 to 4294967295, in bytes.

N/A

/huawei-qos:qos/traffic-queuing/queue-profiles/queue-profile/queue/shaping-ext/pbs

Specifies the peak burst size (PBS), which is the maximum volume of burst traffic that can pass through an interface.

The value is an integer in the range from 10000 to 4294967295, in bytes.

N/A

/ietf-interfaces:interfaces/interface/huawei-qos:qos/marking/trust

Indicates the type of priority to be mapped for packets.

The value is a string. The values are as follows:

  • cos: 802.1p priority

  • dscp: DSCP priority

N/A

/ietf-interfaces:interfaces/interface/huawei-qos:qos/queues/queue-profile

Indicates the name of a queue scheduling profile.

The value must be the name of an existing queue scheduling profile.

N/A

/huawei-qos:qos/wlan/ap-shaping

Indicates whether to enable traffic shaping for packets from an AC to an AP.
The value is of the Boolean type:
  • true: Traffic shaping is enabled for packets from an AC to an AP.
  • false: Traffic shaping is disabled for packets from an AC to an AP.

By default, traffic shaping is disabled for packets from an AC to an AP.
