+Configuration of TRAFFIC dictionary
+-----------------------------------
+
+TRAFFIC dictionary is used for configuration of traffic generator. Default values
+can be found in configuration file ``conf/03_traffic.conf``. These default values
+can be modified by (first option has the highest priorty):
+
+ 1. ``Parameters`` section of testcase defintion
+ 2. command line options specified by ``--test-params`` argument
+ 3. custom configuration file
+
+It is to note, that in case of option 1 and 2, it is possible to specify only
+values, which should be changed. In case of custom configuration file, it is
+required to specify whole ``TRAFFIC`` dictionary with its all values or explicitly
+call and update() method of ``TRAFFIC`` dictionary.
+
+Detailed description of ``TRAFFIC`` dictionary items follows:
+
+.. code-block:: console
+
+ 'traffic_type' - One of the supported traffic types.
+ E.g. rfc2544_throughput, rfc2544_back2back
+ or rfc2544_continuous
+ Data type: str
+ Default value: "rfc2544_throughput".
+ 'bidir' - Specifies if generated traffic will be full-duplex (True)
+ or half-duplex (False)
+ Data type: str
+ Supported values: "True", "False"
+ Default value: "False".
+ 'frame_rate' - Defines desired percentage of frame rate used during
+ continuous stream tests.
+ Data type: int
+ Default value: 100.
+ 'multistream' - Defines number of flows simulated by traffic generator.
+ Value 0 disables multistream feature
+ Data type: int
+ Supported values: 0-65535
+ Default value: 0.
+ 'stream_type' - Stream type is an extension of the "multistream" feature.
+ If multistream is disabled, then stream type will be
+ ignored. Stream type defines ISO OSI network layer used
+ for simulation of multiple streams.
+ Data type: str
+ Supported values:
+ "L2" - iteration of destination MAC address
+ "L3" - iteration of destination IP address
+ "L4" - iteration of destination port
+ of selected transport protocol
+ Default value: "L4".
+ 'pre_installed_flows'
+ - Pre-installed flows is an extension of the multistream"
+ feature. If multistream is disabled, then pre-installed
+ flows will be ignored. It defines if stream specific flows
+ will be inserted into OVS or not.
+ Data type: str
+ Supported values:
+ "Yes" - flows will be inserted into OVS
+ "No" - flows won't be inserted into OVS
+ Default value: "No".
+ 'flow_type' - Defines flows complexity.
+ Data type: str
+ Supported values:
+ "port" - flow is defined by ingress ports
+ "IP" - flow is defined by ingress ports
+ and src and dst IP addresses
+ Default value: "port"
+ 'l2' - A dictionary with l2 network layer details. Supported
+ values are:
+ 'srcmac' - Specifies source MAC address filled by traffic generator.
+ NOTE: It can be modified by vsperf in some scenarios.
+ Data type: str
+ Default value: "00:00:00:00:00:00".
+ 'dstmac' - Specifies destination MAC address filled by traffic generator.
+ NOTE: It can be modified by vsperf in some scenarios.
+ Data type: str
+ Default value: "00:00:00:00:00:00".
+ 'framesize' - Specifies default frame size. This value should not be
+ changed directly. It will be overridden during testcase
+ execution by values specified by list TRAFFICGEN_PKT_SIZES.
+ Data type: int
+ Default value: 64
+ 'l3' - A dictionary with l3 network layer details. Supported
+ values are:
+ 'srcip' - Specifies source MAC address filled by traffic generator.
+ NOTE: It can be modified by vsperf in some scenarios.
+ Data type: str
+ Default value: "1.1.1.1".
+ 'dstip' - Specifies destination MAC address filled by traffic generator.
+ NOTE: It can be modified by vsperf in some scenarios.
+ Data type: str
+ Default value: "90.90.90.90".
+ 'proto' - Specifies deflaut protocol type.
+ Please check particular traffic generator implementation
+ for supported protocol types.
+ Data type: str
+ Default value: "udp".
+ 'l4' - A dictionary with l4 network layer details. Supported
+ values are:
+ 'srcport' - Specifies source port of selected transport protocol.
+ NOTE: It can be modified by vsperf in some scenarios.
+ Data type: int
+ Default value: 3000
+ 'dstport' - Specifies destination port of selected transport protocol.
+ NOTE: It can be modified by vsperf in some scenarios.
+ Data type: int
+ Default value: 3001
+ 'vlan' - A dictionary with vlan encapsulation details. Supported
+ values are:
+ 'enabled' - Specifies if vlan encapsulation should be enabled or
+ disabled.
+ Data type: bool
+ Default value: False
+ 'id' - Specifies vlan id.
+ Data type: int (NOTE: must fit to 12 bits)
+ Default value: 0
+ 'priority' - Specifies a vlan priority (PCP header field).
+ Data type: int (NOTE: must fit to 3 bits)
+ Default value: 0
+ 'cfi' - Specifies if frames can or cannot be dropped during
+ congestion (DEI header field).
+ Data type: int (NOTE: must fit to 1 bit)
+ Default value: 0
+
