Release Feature(s)

Support for deprecated control, action and update APIs (set_transmit_state, set_link_state, set_capture_state, update_flows, set_route_state, send_ping, set_protocol_state, set_device_state) have been removed. Please use following set_control_state, set_control_action and update_config APIs instead of the previous ones. Please refer to go utils and python utils for further details usage.
Most properties in OTG with integer data type have been assigned correct integer format (from uint32, uint64, int32 and int64). Please click here to examine all changes.
Once you upgrade the new ixia-c release, in addition to removing the deprecated APIs from the test programs, data types of some variables in the test programs might need to be changed to avoid compilation errors.

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.

Release Feature(s)

Enabling metric_tags for egress tracking is now also supported on ipv6.src/dst, ipv6.traffic_class, ipv6.flow_label and ipv6.payload_length. [Ixia-C]

  eth := flow.EgressPacket().Add().Ethernet()
  ipv6 := flow.EgressPacket().Add().Ipv6()
  ipv6Tag := ipv6.Dst().MetricTags().Add()
  ipv6Tag.SetName("flow_ipv6_dst")
  ipv6Tag.SetOffset(120)
  ipv6Tag.SetLength(8)

Support is available in gNMI to fetch the drill-down statistics for egress tracking as follows [Ixia-C] details:

  1. Flow level metrics + Tagged Metrics:
      example path: "flows/flow[name=f1]“
  2. Only Flow level metrics:
      example path: "flows/flow[name=f1]/state“
  3. Only Tagged metrics 
      example path: "flows/flow[name=f1]/tagged-metrics“
  4. Filtered Tagged metrics: 
      example path: "flows/flow[name=f1]/tagged-metrics/tagged-metric[name-value-pairs=flow_ipv6_dst=0x2]”

Bug Fix(s)

For flow.duration.continuous type of traffic in Ixia-C, intermittent issue where last few packets in a traffic flow were not accounted for in flow_metrics.frames_rx statistics after stopping a flow is fixed.
Proper error mesage is propagated to user if user has used community edition of Ixia-C (instead of licensed edition) and invoked any API/Configuration not supported by it. example: Device configuration is not supported in free version of controller.

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.

ixia-c-one	0.0.1-3927

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.
```
  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.

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/* .

Release v0.0.1-1622

25th June, 2021

About

This build contains support for protocols GRE and VXLAN (RFC 2784), enabling/disabling flow metrics and some bug fixes.

Build Details

Component	Version
Open Traffic Generator API	0.4.0
snappi	0.4.0
ixia-c-controller	0.0.1-1622
ixia-c-traffic-engine	1.4.0.1
ixia-c-app-usage-reporter	0.0.1-36

New Feature(s)

Flow header configuration for protocols GRE and VXLAN (RFC 2784) are now supported.
Flow metrics is now disabled by default to allow transmitting packets with unaltered payload(i.e. without any timestamps and instrumentation bytes embedded in it).
Flow metrics (including metrics that are its sub-properties, e.g. latency and timestamp) can now be explicitly enabled on per-flow basis.

Bug Fixes

ixia-c-controller can now safely serve multiple parallel requests from different clients preventing any undefined behavior.
Port metrics can now be fetched for ports which are not part of flow configuration.
Providing port locations for ixia-c-traffic-engine running in unsupported mode will now throw a user-friendly error.
Default values for increment and decrement properties in flow header fields are now aligned per Open Traffic Generator API.

Known Issues

Checksum field in GRE header currently cannot be set.
The metric loss in flow metrics is currently not supported.

Release v0.0.1-1388

New Feature(s)

Ixia-c now supports delay parameter in flow configuration. Refer to v0.3.10 of the Open Traffic Generator API specification for more details.

Bug Fixes

The flow configuration parameter inter_burst_gap when specified in nanoseconds can now be set to a value larger than 4.2 seconds.
Invalid values can now be set for the phb (per hob behavior) field in the DSCP bits in the IPv4 header.
The set_config method will return an error when flows are over subscribed.
Fixed an error in calculation for packet counts when duration is set in terms of fixed_seconds.

Known Issues

The metrics frames_rx_rate and bytes_rx_rate in port statistics are not calculated correctly and are always zero.
The metric min_latency_ns in flow statistics is not calculated correctly and is always zero.
