Ron Stone f125a8b892 Remove spurious escapes (r8,dsR8)

This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Add Data Networks Using the CLI

You can add data networks using the CLI. You can set up flat, VLAN and VXLAN data networks over physical networks using the command-line interface. The data networks model the L2 networks that are attached to node data, pci-sriov and pci-passthrough interface.

To create a data network using the CLI, use the following command.
```
~(keystone_admin)$ system datanetwork-add -d <description> -m <mtu> -p <port> -g <group> -t <ttl> -M <mode> <name> <type>
```
where

<description>

A description of the data network.

<mtu>

The of the data network.

Note

To attach to the data network, data interfaces must be configured with an equal or larger .

This is not used by the Kubernetes plugin. In order to address the in Kubernetes, the network attached definition needs to use the tuning plugin. For more details, see the examples in Create Network Attachment Definitions <creating-network-attachment-definitions>.

<port>

The port of the data network.

<group>

The multicast group of the data network.

<ttl>

The time-to-live of the data network.

<mode>

For networks of <type> vxlan only, mode can be either dynamic or static.

If set to dynamic, <group> must also be specified.

<name>

The name assigned to the data network.

<type>

The type of data network to be created (flat, vlan, or vxlan)

Note

vxlan is only applicable to .

For example, to add a VLAN data network named datanet-a:
```
~(keystone_admin)$ system datanetwork-add datanet-a vlan
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| id           | 2                                    |
| uuid         | 104071a4-1c26-4383-ba07-72e05316d540 |
| name         | datanet-a                            |
| network_type | vlan                                 |
| mtu          | 1500                                 |
| description  | None                                 |
+--------------+--------------------------------------+
```

For the application, after creating a data network of the VLAN or VXLAN type, you can assign one or more segmentation ranges consisting of a set of consecutive VLAN IDs (for VLANs) or VNIs (for VXLANs) using the openstack network segment range create command. Segmentation ranges are required in order to set up project networks.

Note

Segmentation ranges are not required in order to attach interfaces and unlock openstack-compute labeled worker nodes.
