Release Feature(s):

Ixia-C, Ixia Chassis & Appliances(Novus, AresOne) & UHD400: Support added for retrieval of BGP MPLS IPv4/v6 labeled unicast prefixes. details

To enable storage of MPLS prefixes,

    bgpPeer.LearnedInformationFilter().SetIpv4MplsUnicastPrefix(true).SetIpv6MplsUnicastPrefix(true)

To fetch prefixes,

    req := gosnappi.NewStatesRequest()
    req.BgpPrefixes().SetBgpPeerNames(peerNames)
    req.BgpPrefixes().SetPrefixFilters([]gosnappi.BgpPrefixStateRequestPrefixFiltersEnum{
        gosnappi.BgpPrefixStateRequestPrefixFilters.IPV4_MPLS_UNICAST,
        gosnappi.BgpPrefixStateRequestPrefixFilters.IPV6_MPLS_UNICAST,
    })
    res, _ := client.GetStates(req)
    // MPLS Prefix information can be accessed within the following objects.
    res.BgpPrefixes().Ipv4MplsUnicastPrefixes()
    res.BgpPrefixes().Ipv6MplsUnicastPrefixes()

Note: gNMI support will be added in subsequent sprints.

Ixia-C, Ixia Chassis & Appliances(Novus, AresOne) & UHD400: Support added for sending and withdrawing IPv4 routes from BGPv4 peers using MP_REACH/UNREACH NLRIs. details
```
    bgpPeer := bgpIntf.
            Peers().
            Add().
            ...
            .SetTraditionalNlriForIpv4Routes(false) 
```
Note: Default behavior is to send/withdraw IPv4 routes from BGPv4 peers using Traditional REACH/UNREACH NLRI.

Bug Fix(s):

Ixia-C & UHD400 Issue is fixed in DHCPv4 client where the client was unable to use the offered address provided by pre-configured DHCPv4 server.

Ixia Chassis & Appliances(Novus, AresOne) Issue is fixed for RSVP-TE where assigned ERO was not being published for get_states for rsvp_lsps[i].ipv4_lsps[j].eros on the ingress test port.

Known Issues

Ixia Chassis & Appliances(Novus, AresOne): If keng-layer23-hw-server version is upgraded/downgraded, the ports which will be used from this container must be rebooted once before running the tests.
Ixia Chassis & Appliances(Novus, AresOne): StartProtocols/set_control_state.protocol.all.start can get stuck till the time all DHPCv4/v6 clients receive the leased IPv4/v6 addresses from the DHCPv4/v6 server/relay agent. This may result in getting "context deadline exceeded" error in the test program.
UHD400: Packets will not be transmitted if flows[i].rate.pps is less than 50.
UHD400: values for fields in flow packet headers can be created with maximum length of 1000 values. If larger set of values are required for a field which are random, please use random instead of values.
Ixia-C: Flow Tx is incremented for flow with tx endpoints as LAG, even if no packets are sent on the wire when all active links of the LAG are down.
Ixia-C: The metric loss in flow metrics is currently not supported.
Ixia-C: When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets.

Release Feature(s):

Ixia Chassis & Appliances(Novus, AresOne): Support added for enabling and fetching data-integrity port statistics in set_config and get_metrics. details
- To configure enable data-integrity at global level.
```
    cfg.Options().PortOptions().SetDataIntegrity(true)
```
- to fetch data-integrity metrics use the following snippet.
```
    req := gosnappi.NewMetricsRequest()
    reqPort := req.Port()
    reqPort.SetPortNames([]string{"port1", "port2"})
    res, err := client.GetMetrics(req)
```
  - If data-integrity is enabled, new object called data-integrity will be returned in the port metrics which will contain two new fields total-frames-rx and error-frames-rx.
- gNMI support details:
```
    ports/port[name=*]/state/data-integrity
```
  Note: featureprofiles users needs to sync to latest otherwise retrieval of OTG Port counters/state using gNMI might give incorrect results.
Note: Only frames generated from flows will have data-integrity enabled.

Ixia-C, Ixia Chassis & Appliances(Novus, AresOne) & UHD400: Support added for capturing rx packets on ports using pcapng format.

    c1 := config.Captures().Add().SetName("Capture")
    c1.SetPortNames([]string{"port1"})
    c1.SetFormat("pcapng")

Ixia-C, Ixia Chassis & Appliances(Novus, AresOne) & UHD400: gNMI support is added for link-bandwidth subtype in transitive_2octet_as_type under extended_communities for BGP/BGP+ routes in get_states. details
```
  bgp-peers/bgp-peer[name=*]/unicast-ipv4-prefixes/unicast-ipv4-prefix/state/extended-community[i]/structured/transitive_2octet_as_type/link_bandwidth_subtype

  bgp-peers/bgp-peer[name=*]/unicast-ipv6-prefixes/unicast-ipv6-prefix/state/extended-community[i]/structured/transitive_2octet_as_type/link_bandwidth_subtype
```
Note: featureprofiles users needs to sync to latest otherwise retrieval of OTG BGP counters/state using gNMI might give incorrect results.

Bug Fix(s):

Ixia-C & UHD400: Issue is fixed in BGP/BGP+ where the pod/container would sometimes restart on trying to start BGP for the first time with ixstack_bgp_accept_check backtrace present in the protocol-engine logs, especially on slower systems.
Ixia-C & UHD400: The default mode of transmission of BGPv4 routes from BGP peers is changed from MP_REACH/UNREACH to Traditional REACH/UNREACH, to bring it in sync with default behavior of Ixia Chassis & Appliances(Novus, AresOne).
otg-gnmi-server: Issue is fixed in models-yang due to which error schema "lsp-id": "192000002001-00-00" does not match regular expression pattern "^([0-9a-fA-F]*)$" would be seen during gNMI client validation when accessing ISIS lsp-id using /isis-routers/isis-router[name=*]/state/link-state-database/lsp-states/lsps[lsp-id=*][pdu-type=*]/state/lsp-id.

    }

Note: gNMI support will be added in the subsequent sprint once ondatra incorporates latest models-yang.

Ixia Chassis & Appliances(Novus, AresOne): Support added for auto detection of port left in dirty state by other user and automatic reboot during set_config.

Bug Fix(s):

otg-gnmi-server: Issue is fixed in models-yang due to which error validation failed: /device/flows/flow/tagged-metrics/tagged-metric/state/tags/tag-value/value-as-hex: schema "value-as-hex": "0x02" does not match regular expression pattern "^([0-9a-fA-F]*)$" would be seen during gNMI client validation for tagged metrics.
Ixia-C, Ixia Chassis & Appliances(Novus, AresOne) & UHD400: Issue is fixed where incorrect packet template related to ICMPv6 over IPv4 and ICMPv4 over IPv6 was incorrectly accepted by the controller, resulting in incorrect behavior including context deadline exceeded error. Instead proper error will now be returned on set_config and only valid configurations of icmp over ipv4 and icmpv6 over ipv6 will be accepted.
Ixia Chassis & Appliances(Novus, AresOne): Issue is fixed where in certain scenarios the time taken for set_config API was seen to be increasing for large number of iterations.

Ixia Chassis & Appliances(Novus, AresOne): Support of Ingress Flow tracking is added for any combination of supported fields with metric_tags up to a maximum combined tracking bits of 12, which includes flow tracking as well.

    flow := cfg.Flow().Add()
    flow.Packet().Add().Ethernet()
    ipv4 := flow.Packet().Add().Ipv4()
    ipv4.Src().MetricTags().Add().SetName("src").SetLength(32) // Currently the maximum length of the field being tracked must be provided.
    ipv4.Dst().MetricTags().Add().SetName("dst").SetLength(32) // Ingress tracking for partial bits in a field is not supported.

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.

Support is available in gNMI to fetch the drill-down statistics for ingress tracking as follows. details:

    1. Flow level metrics + Tagged Metrics:
        example path: "flows/flow[name=f1]“
    2. Only Tagged metrics

Bug Fix(s):

Ixia Chassis & Appliances(Novus): Issue is fixed where if protocols were restarted followed by restart of previously configured flows , flow packets were not being transmitted on the wire and flow tx metrics stayed at 0. This issue is specific to Novus load module.
Ixia Chassis & Appliances(Novus, AresOne): Issue is fixed where for certain cases multiple consecutive API calls would fail and result in 'potential deadlock' related messages in keng-layer23-hw-server logs. Now if keng-layer23-hw-server is stuck & busy on processing last API, future API calls will immediately fail with proper error instead of earlier 'context deadline' error after timeout of 10 min.

Known Issues

Ixia Chassis & Appliances(Novus, AresOne): If keng-layer23-hw-server version is upgraded/downgraded, the ports which will be used from this container must be rebooted once before running the tests.
Ixia Chassis & Appliances(Novus, AresOne): StartProtocols/set_control_state.protocol.all.start can get stuck till the time all DHPCv4/v6 clients receive the leased IPv4/v6 addresses from the DHCPv4/v6 server/relay agent. This may result in getting "context deadline exceeded" error in the test program.
UHD400: Packets will not be transmitted if flows[i].rate.pps is less than 50.
UHD400: values for fields in flow packet headers can be created with maximum length of 1000 values. If larger set of values are required for a field which are random, please use random instead of values.
Ixia-C: Flow Tx is incremented for flow with tx endpoints as LAG, even if no packets are sent on the wire when all active links of the LAG are down.
Ixia-C: The metric loss in flow metrics is currently not supported.
Ixia-C: When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets.
