ironic.common.neutron.add_ports_to_network(task, network_uuid, security_groups=None)

Create neutron ports to boot the ramdisk.

Create neutron ports for each pxe_enabled port on task.node to boot the ramdisk.

If the config option ‘neutron.add_all_ports’ is set, neutron ports for non-pxe-enabled ports are also created – these neutron ports will not have any assigned IP addresses.

Parameters:

• task – a TaskManager instance.

• network_uuid – UUID of a neutron network where ports will be created.

• security_groups – List of Security Groups UUIDs to be used for network.

Raises:

NetworkError

Returns:

a dictionary in the form {port.uuid: neutron_port[‘id’]}

ironic.common.neutron.get_client(token=None, context=None, auth_from_config=False)

Retrieve a neutron client connection.

Parameters:

• context – request context, instance of ironic.common.context.RequestContext

• auth_from_config – (boolean) When True, use auth values from conf parameters

Returns:

A neutron client.

ironic.common.neutron.get_local_group_information(task, portgroup)

Extract the portgroup information.

The information is returned in the form of:

{
    'id': portgroup.uuid,
    'name': portgroup.name,
    'bond_mode': portgroup.mode,
    'bond_properties': {
        'bond_propertyA': 'valueA',
        'bond_propertyB': 'valueB',
    }
}

Parameters:

• task – a task containing the Node object.

Returns:

port group information as a dict

ironic.common.neutron.get_neutron_port_data(port_id, vif_id, client=None, context=None)

Gather Neutron port and network configuration

Query Neutron for port and network configuration, return whatever is available.

Parameters:

• port_id – ironic port/portgroup ID.

• vif_id – Neutron port ID.

• client – Optional a Neutron client object.

• context (ironic.common.context.RequestContext) – request context

Raises:

NetworkError

Returns:

a dict holding network configuration information associated with this ironic or Neutron port.

ironic.common.neutron.get_node_portmap(task)

Extract the switch port information for the node.

The information is returned in the form of:

{
    port.uuid: {
        'switch_id': 'abc',
        'port_id': 'Po0/1',
        'other_llc_key': 'val'
    }
}

Parameters:

task – a task containing the Node object.

Returns:

port information as a dict

ironic.common.neutron.get_physnets_by_port_uuid(client, port_uuid)

Return the set of physical networks associated with a neutron port.

Query the network to which the port is attached and return the set of physical networks associated with the segments in that network.

Parameters:

• client – A Neutron client object.

• port_uuid – UUID of a Neutron port to query.

Returns:

A set of physical networks.

Raises:

NetworkError if the network query fails.

Raises:

InvalidParameterValue for missing network.

ironic.common.neutron.is_ovn_vtep_port(port_info)

Check if the current port is an OVN VTEP port

Parameters:

port_info – an instance of ironic.objects.port.Port or port data as a port like object

Returns:

Boolean indicating if the port is an OVN VTEP port

ironic.common.neutron.is_smartnic_port(port_data)

Check that the port is Smart NIC port

Parameters:

port_data – an instance of ironic.objects.port.Port or port data as dict.

Returns:

A boolean to indicate port as Smart NIC port.

ironic.common.neutron.remove_neutron_ports(task, params)

Deletes the neutron ports matched by params.

Parameters:

• task – a TaskManager instance.

• params – Dict of params to filter ports.

Raises:

NetworkError

ironic.common.neutron.remove_ports_from_network(task, network_uuid)

Deletes the neutron ports created for booting the ramdisk.

• task – a TaskManager instance.

• network_uuid – UUID of a neutron network ports will be deleted from.

Raises:

NetworkError

ironic.common.neutron.rollback_ports(task, network_uuid)

Attempts to delete any ports created by cleaning/provisioning

Purposefully will not raise any exceptions so error handling can continue.

Parameters:

• task – a TaskManager instance.

• network_uuid – UUID of a neutron network.

ironic.common.neutron.unbind_neutron_port(port_id, client=None, context=None, reset_mac=True)
