Release Features(s)
- Ixia Chassis & Appliances(Novus, AresOne): Support added for new traffic applying infrastructure.
- Instead of "Failed to apply flow configurations due to: Please contact Ixia Support." ,
- In scenarios where underlying hardware module doesn't have the resources to apply the flow a proper error message such as "Failed to apply flow configurations due to: Error occurred for flow 'ipv6flowlabel': The Tx Ports of the flow do not support the combinations of fields and size of value lists configured. Please reduce the size of the value lists or/and fields with value lists configured or use a load module ( or variant) with more resources." Based on this either test can be modified or appropriate load modules can be used for the test.
- There were certain scenarios with large
values
in packet fields in the flows which were failing with above error inspite of being within the modules capabilities and can now be applied without any error.
- Earlier configuration with multiples flows with large
values
in packet fields would fail with error as "Failed to apply flow configurations due to: Traffic configuration exceeds port background memory size.". This issue is also fixed with the upgrade to new traffic applying infrastructure. - Issue where correct
values
/increment
/decrement
forethernet.src/dst
was not being transmitted on the wire is fixed. -
In this new infrastructure, traffic will be directly applied to the hardware ports resulting in better performance on
set_transmit_state
. -
gosnappi: Client side file organization of the
gosnappi
sdk is modified to allow for better auto-completion support when writing test programs. Note: Client must be upgraded to gosnappi v1.7.2. -
Ixia-C, UHD400: Support added for DHCPv4 Client and Server in control plane. details
- User will be the able to configure DHCPv4 Client and Server by the following code snippet. More comprehensive B2B example

random
in following flow fields. details ipv4.src/dst
ipv6.flow_label
tcp.src_port/dst_port
-
udp.src_port/dst_port
-
Ixia-C: New environment variable
OPT_ADAPTIVE_CPU_USAGE=""
is introduced for docker based ixia-c-traffic-engine setups which enables adaptive CPU usage on therx
port for a flow. By default a non adaptive receiver is used when therx
CPU core usage reaches up to 100%. The adaptive receiver reducesrx
CPU core usage from 100% to less than 5% in idle mode. To disable the adaptive receiver please remove this environment variable from docker run command. It is recommended to also pin therx
to specific cpu cores using theARG_CORE_LIST
environment variable when enablingOPT_ADAPTIVE_CPU_USAGE
. -
Example docker usage:
docker run --net=host --privileged --rm -d \
-e OPT_LISTEN_PORT="5555" \
-e ARG_CORE_LIST="1 2 3" \
-e ARG_IFACE_LIST="virtual@af_packet,enp7s0" \

Release Features(s)
- Ixia Chassis & Appliances(Novus, AresOne): Support added for DHCPv4 client interfaces to be used as source/destination for device traffic.
- In this the learned IPv4 address from the DHCPv4 server is automatically populated in
ipv4.src/dst
if the choice is set toauto.dhcp
.
clientToServerFlow.SetName("ClientToServer").TxRx().Device().
SetTxNames([]string{"DHCPv4ClientName"}).

SetRxNames([]string{"DHCPv4ClientName"})
serverToClientFlowIp := serverToClientFlow.Packet().Add().Ipv4()
serverToClientFlowIp.Dst().Auto().Dhcp()
tx_rx.device.tx_names
, hence a separate flow has to be configured for each DHCPv4 client if packet[i].ipv4.src.auto.dhcp
is set.
- Ixia-C: Support added for multiple address groups in BGPv4/v6 routes.
Bug Fix(s)
-
Ixia-C, Ixia Chassis & Appliances(Novus, AresOne): Issue where if a BGPv4/v6 prefix with extended-community or community attributes was updated via a BGP Update with the extended-community or community attribute deleted without a Route Withdraw in between , the subsequent get_states call on the bgp prefixes would incorrectly continue to show the extended-community or community attributes learned via the previous received Update is fixed.
-
Ixia-C: Issue where If a test was setup such that only test port would initiate ARP/ND and time taken to configure the soft-DUT connected to the test port was taking extended time such that it would not respond to ARP/ND requests within 10s, ARP/ND procedures would fail resulting in test failures in ARP/ND verification step is fixed.
-
Ixia-C: Issue where if a IPv6 address on the emulated interface was configured in non-shortest format e.g.
2001:0db8::192:0:2:2
instead of2001:db8::192:0:2:2

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

- API version compatibility check is now automatically performed between ixia-c containers upon API calls to
ixia-c-controller
. It can be disabled by bootingixia-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 = snappi.api(version_check=True) ``` In upcoming releases, this will be enabled by default.
Known Issues
- Supported value for

[Breaking Change] Auto learning of destination MAC is currently supported for both IPv4 and IPv6 Flows without any VLAN(originated from device endpoints) by setting ethernet destination with
choice
asauto
in the packet. Earlier this was working by setting ethernet destination mac with "00:00:00:00:00:00" in the packet header. ``` { "choice": "ethernet", "ethernet": { "dst": { "choice": "auto" }, "src": { "choice": "value", "value": "00:00:01:01:01:01" } } }, ````

- Flow header configuration for protocols
GRE
andVXLAN (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
andtimestamp
) 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
anddecrement
properties in flow header fields are now aligned per Open Traffic Generator API.
