Configure VLAN Interfaces Using the CLI
=======================================

You can use the CLI to attach |VLAN| interfaces to networks.

#.  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

#.  Create a |VLAN| interface.

    Use a command of the following form:

    .. code-block:: none

        ~(keystone_admin)$ system host-if-add <hostname> -V <--vlan_id> -c <--ifclass> <interface name> <ethname> [<datanetwork>]

    where the following options are available:

    **interface name**
        A name or UUID for the interface \(Required\).

        .. caution::
            To avoid potential internal inconsistencies, do not use upper
            case characters when creating interface names. Some components
            normalize all interface names to lower case.

    **vlan\_id**
        The |VLAN| identifier for the network.

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

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

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

    **datanetworks**
        A list of data networks, delimited by quotes and separated by commas;
        for example, "net-a, net-b". To specify a single data network,
        omit the quotes. This parameter is required only if the <networktype>
        is set to data,pci-sriov or pci-passthru.

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

    For example, to attach a |VLAN| interface named **clusterhost0** with
    |VLAN| ID **22** to the cluster-host network using Ethernet interface
    **enp0s8** on **storage-0**:

    .. code-block:: none

        ~(keystone_admin)$ system host-if-add storage-0 -V 22 -c platform clusterhost0 vlan enp0s8

#.  Attach the newly created |VLAN| interface to a network.

    Use a command of the following format:

    .. code-block:: none

        ~(keystone_admin)$ system interface-network-assign <hostname> <interface name> <network>

    For example:

    .. code-block:: none

        ~(keystone_admin)$ system interface-network-assign storage-0 clusterhost0 cluster-host
