#
# NFVbench default configuration file
#
# This configuration file is ALWAYS loaded by NFVbench and should never be modified by users.
# To specify your own property values, always define them in a separate config file
# and pass that file to the script using -c or --config <file>
# Property values in that config file will override the default values in the current file
#
---
# IMPORTANT CUSTOMIZATION NOTES
# There are roughly 2 types of NFVbench config based on the OpenStack encaps used:
# - VLAN (OVS, OVS-DPDK, ML2/VPP)
# Many of the fields to customize are relevant to only 1 of the 2 encaps
# These will be clearly labeled "VxLAN only" or "VLAN only"
# Fields that are not applicable will not be used by NFVbench and can be left empty
#
# All fields are applicable to all encaps/traffic generators unless explicitly marked otherwise.
# Fields that can be over-ridden at the command line are marked with the corresponding
# option, e.g. "--interval"


# The OpenStack openrc file to use - must be a valid full pathname. If running
# in a container, this path must be valid in the container.
#
# The only case where this field can be empty is when measuring a system that does not run
# OpenStack or when OpenStack APIs are not accessible or OpenStack APis use is not
# desirable. In that case the EXT service chain must be used.

# from the package root directory named "nfvbench-<version>.qcow2" and
# upload that file. The image name will be "nfvbench-<version>"
# This can be overridden by specifying here a pathname of a file
# that follows the same naming convention.
# In most cases, this field should be left empty as the packaging should
# include the proper VM image file

    #     generator.

    # Traffic Generator Profiles
    # In case you have multiple testbeds or traffic generators,

    # traffic generator and leave all other fields unchanged
    #
    # Generator profiles are listed in the following format:
    # `name`: Traffic generator profile name (use a unique name, no space or special character)
    #         DFo not change this field
    # `tool`: Traffic generator tool to be used (currently supported is `TRex`).
    #         Do not change this field
    # `ip`: IP address of the traffic generator.
    #       The default loopback address is used when the traffic generator runs on the same host
    #       as NFVbench.
    # `cores`: Specify the number of cores for running the TRex traffic generator.
    #          ONLY applies to trex-local.
    # `software_mode`: Advice TRex to use software mode which provides the best compability. But
    #                  note that TRex will not use any hardware acceleration technology under
    #                  software mode, therefore the performance of TRex will be significantly
    #                  lower. ONLY applies to trex-local.
    #                  Recommended to leave the default value (false)
    # `interfaces`: Configuration of traffic generator interfaces.
    # `interfaces.port`: The port of the traffic generator to be used (leave as 0 and 1 resp.)
    # `interfaces.switch_port`: Leave empty (deprecated)
    # `interfaces.pci`: The PCI address of the intel NIC interface associated to this port
    #                   This field is required and cannot be empty
    #                   Use lspci to list the PCI address of all devices
    #                   Example of value: "0000:5e:00.0"
    # `intf_speed`: The speed of the interfaces used by the traffic generator (per direction).

    #               Recommended to leave this field empty.
