Release Features(s)

• A new property egress_packet inside flow has been introduced to configure expected packet shape as it is received on the test port.
  go eth := flow.EgressPacket().Add().Ethernet() ipv4 := flow.EgressPacket().Add().Ipv4()

• A new property metric_tags has been introduced for fields inside headers configured in egress_packet to enable tracking metrics for each applicable value corresponding to a portion of or all bits inside the field.

    ipv4Tag := ipv4.Dst().MetricTags().Add()
    ipv4Tag.SetName("flow_ipv4_dst")
    ipv4Tag.SetOffset(24)
    ipv4Tag.SetLength(8)

  • As of this release, enabling metric_tags is only supported on ethernet.src/dst, ipv4.src/dst, ipv4.tos. Support for more fields shall be added in upcoming releases.

  • Limitations:

    • The total number of tracking bits available on an ixia-c Rx port is 12 bits. Out of these some of the bits are needed for tracking flows, example 2 flows need 1 bit, 4 flows need 2 bits, 8 flows need 3 bits etc. The sum of metric_tag.length for each field inside each header configured in egress_packet cannot exceed the remaining bits available on the Rx port.
    • The total number of tracking fields that can be configured across a set of flows which have the same Rx port, is two.

• A new property is introduced in get_metrics.flow to fetch tagged metrics.

• User can set get_metrics.flow.tagged_metrics.include=false not to include tagged_metrics in the flow_metrics response.
• Specific tagged_metrics can be fetched by setting get_metrics.flow.tagged_metrics.filters[i].name.

Known Issues

• Supported value for flows[i].metrics.latency.mode is cut_through.
• The metric loss in flow metrics is currently not supported.
• When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets.

Features(s)

• All API response errors over gRPC and HTTP transport can now be inspected like so:

      # snippet of error handling in snappi
      try:
      # call set config
      api.set_config(payload)
      except Exception as e:
          err = api.from_exception(e)  # helper function to parse exception
          if err is not None: # exception was of otg error format
              print(err.code)
              print(err.errors)
          else: # some other exception
              print(e)

      // gosnappi snippet for error handling
      resp, err := api.SetConfig(config)
      if err != nil {
          // helper function to parse error
          // retuns a bool with err, indicating wheather the error was of otg error format 
          errSt, ok := api.FromError(err)
          if ok {
              fmt.Println(errSt.Code())
              if errSt.errSt.HasKind() {
              fmt.Println(errSt.Kind())
              }
              fmt.Println(errSt.Errors())
          } else {
              fmt.Println(err.Error())
          }
      }

Features(s)

• Warning messages shall now be automatically printed on STDOUT if a property or an API with status deprecated or under-review is exercised in snappi / gosnappi. This may also lead to linters raising deprecation error.
• New API endpoints /control/state and /control/action have been exposed consolidating pre-existing API endpoints inside /control/ (now deprecated) in order to reduce API surface and introducing clean organization. Please see snappi-tests utils for usage.
• API endpoints /results/* have now been renamed to /monitor/* .

Known Issues

• Supported value for flows[i].metrics.latency.mode is cut_through.
• The metric loss in flow metrics is currently not supported.

Features(s)

• API version compatibility check is now automatically performed between ixia-c containers upon API calls to ixia-c-controller . It can be disabled by booting ixia-c-controller container with --disable-version-check flag.
• API version compatibility check can now be automatically performed between snappi/gosnappi and ixia-c-controller upon API calls by enabling version check flag in API handle like so:
  • gosnappi

      api := gosnappi.NewApi()
      api.SetVersionCompatibilityCheck(true)
  

  • snappi

      api = snappi.api(version_check=True)
  

  In upcoming releases, this will be enabled by default.

Known Issues
