Attach Ethernet Interfaces to Networks Using the CLI¶
You can use the CLI to attach Ethernet interfaces to networks.
Ethernet interfaces are created automatically.
Procedure
List the attached interfaces.
For example, to list all the interfaces on the system, use the system host-if-list and include the

Modify the interface and attach it to a network.
Use a command sequence of the following form:
~(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 Interface Settings.
For example, to attach an interface named enp0s3 to the OAM network, using Ethernet interface enp0s3 on controller-1:
Lock the host:
~(keystone_admin)]$ system host-lock controller-1
To modify the interface enp0s3 class type from
nonetoplatform, execute the following:~(keystone_admin)$ system host-if-modify -n enp0s3 -c platform controller-1 enp0s3 +-------------------+---------------------------------------+ | Property | Value | +-------------------+---------------------------------------+ | ifname | enp0s3 | | ifclass | platform | | iftype | ethernet | | ports | [u'enp0s3'] | | providernetworks | None | | imac | 08:00:27:58:0c:e5 | | imtu | 1500 | | aemode | None | | schedpolicy | None | | txhashpolicy | None | | uuid | 14300770-13bf-48fd-b9af-756ec7d8adc1 | | ihost_uuid | e1c47086-3230-4b92-91d0-208c55130a52 | | vlan_id | None | | uses | [] | | used_by | [] | | created_at | 2015-12-10T14:24:25.967362+00:00 | | updated_at | 2015-12-10T17:01:08.761323+00:00 | | sriov_numvfs | 0 | | accelerated | [u'True'] | +-------------------+---------------------------------------+
To assign enp0s3 interface to OAM network, execute the following:
~(keystone_admin)$ system interface-network-assign controller-1 enp0s3 oam
Unlock the host:
~(keystone_admin)$ system host-unlock controller-1
Interface Network Configuration for PCI-SRIOV Interfaces¶
Platform networks must be associated with platform interfaces. If a platform network needs to be associated with a PCI-SR-IOV type interface, a logical platform interface must be created that references the PCI-SR-IOV interface. In this case, the platform network functions as a standard platform interface. This ensures consistent configuration between the platform network and its associated platform interface. This procedure does not consume additional physical system resources.
In the following example, the platform interface pxeboot0 references the sriov0 interface.

Then, the pxeboot network must be associated with the pxeboot0 platform interface.
