Attach Ethernet Interfaces to Networks Using the CLI
====================================================

You can use the CLI to attach Ethernet
interfaces to networks.

Ethernet interfaces are created automatically.

#.  List the attached interfaces.

    To list all interfaces, use the :command:`system host-if-list` command
    and include the ``-a`` flag.

    .. code-block:: none

        ~(keystone_admin)$ system host-if-list -a controller-0

#.  Attach an interface to a network.

    Use a command sequence of the following form:

    .. code-block:: none

        ~(keystone_admin)$ system host-if-modify -n <ifname> -m <mtu> -c <ifclass> <hostname> <ethname> [--ipv4-mode=ip4_mode [ipv4-pool addr_pool]] [--ipv6-mode=ip6_mode [ipv6-pool addr_pool]]
        ~(keystone_admin)$ system interface-network-assign <hostname> <ifname> <network>

    where the following options are available:

    **ifname**
        A name for the interface.

    **mtu**
        The |MTU| for the interface.

    **ifclass**
        The class of the interface. The valid classes are **platform**,
        **data**, **pci-sriov**, and **pci-passthrough**.

    **network**
        The name or ID of the network to assign the interface to.

    **hostname**
        The name or UUID of the host.

    **ethname**
        The name or UUID of the Ethernet interface to use.

    **ip4\_mode**
        The mode for assigning IPv4 addresses to a data interface
        \(static or pool.\)

    **ip6\_mode**
        The mode for assigning IPv6 addresses to a data interface
        \(static or pool.\)

    **addr\_pool**
        The name of an IPv4 or IPv6 address pool, for use with the pool mode
        of IP address assignment for data interfaces.

    For valid values, see :ref:`Interface Settings <interface-settings>`.

    For example, to attach an interface named **enp0s3** to
    the |OAM| network, using Ethernet interface **enp0s3** on **controller-1**:

    .. code-block:: none

        ~(keystone_admin)$ system host-if-modify -n enp0s3 -c platform controller-1 enp0s3
