Configure Aggregated Ethernet Interfaces Using the CLI

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

supports up to four ports in a .

For more about link aggregation modes and policies, see Link Aggregation Settings <link-aggregation-settings>.

1. List the attached interfaces.

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

   ~(keystone_admin)$ system host-if-list -a controller-0
   +---...+----------+----------+...+---------------+...+-------------------+
   | uuid | name     | class    |   | ports         |   | data networks     |
   +---...+----------+----------+...+---------------+...+-------------------+
   | 68...| ens787f3 | None     |   | [u'ens787f3'] |   | []                |
   | 79...| data0    | data     |   | [u'ens787f0'] |   | [u'group0-data0'] |
   | 78...| cluster0 | platform |   | []            |   | []                |
   | 89...| ens513f3 | None     |   | [u'ens513f3'] |   | []                |
   | 97...| ens803f1 | None     |   | [u'ens803f1'] |   | []                |
   | d6...| pxeboot0 | platform |   | [u'eno2']     |   | []                |
   | d6...| mgmt0    | platform |   | []            |   | []                |
   +---...+----------+----------+...+---------------+...+-------------------+

2. Create an aggregated Ethernet interface and attach it to a network.

   Use a command of the following form:

   ~(keystone_admin)$ system host-if-add <hostname> -m <mtu>  -a <aemode> -x <txhashpolicy> <ifname> ae <ethname1> <ethname2>

   where the following options are available:

   ifname

   A name for the interface.

   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.

   mtu

   The for the interface.

   Note

   For a data interface, the must be equal to or larger than the of the provider network to which the interface is attached.

   aemode

   The link aggregation mode.

   policy

   The balanced tx distribution hash policy.

   hostname

   The name or UUID of the host.

   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-passhtru.

   Note

   For networks other than data networks, the value none is required.

   ethname1, ethname2

   The names or UUIDs of the member interfaces.

   For example, to attach an aggregated Ethernet interface named ae0 to data networks net-a and net-b, using member interfaces enp0s9 and enp0s10 on controller-0:

   ~(keystone_admin)$ system host-if-add controller-0 -a balanced -x layer2 ae0 ae enp0s9 enp0s10
   ~(keystone_admin)$ system interface-datanetwork-assign controller-0 ae0 providernet-net-a
   ~(keystone_admin)$ system interface-datanetwork-assign controller-0 ae0 providernet-net-b
