Class Map QoS

Configure Quality of Service (QoS) class maps on a device. Class maps are used to classify traffic based on various criteria such as DSCP values, MPLS experimental bits, QoS groups, and traffic classes.

Example YAML Code:

Example-1: Create a class map with DSCP matching.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        class_map_qos:
          - class_map_name: "TEST"
            description: "description1"
            match_dscp: [46]
            match_mpls_experimental_topmost: [5]

Example-2: Create a class map with multiple DSCP values.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        class_map_qos:
          - class_map_name: "VOICE_CLASS"
            description: "Voice traffic classification"
            match_dscp: [46, 34]

Example-3: Create a class map with DSCP range matching.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        class_map_qos:
          - class_map_name: "RANGE_CLASS"
            description: "DSCP range classification"
            match_any: true
            match_dscp: ["0-5"]

Example-4: Create a class map with DSCP code point names.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        class_map_qos:
          - class_map_name: "VIDEO_CLASS"
            description: "Video traffic classification"
            match_any: true
            match_dscp: ["af41", "af42", "af43"]

Example-5: Create a class map with QoS group matching.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        class_map_qos:
          - class_map_name: "DATA_CLASS"
            description: "Data traffic classification"
            match_qos_group: [1, 2, 3]

Example-6: Create a class map with traffic class matching.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        class_map_qos:
          - class_map_name: "PREMIUM_CLASS"
            description: "Premium traffic classification"
            match_traffic_class: [4, 5]
