Applied M. Camp's comments on patchset 4. Also, some additional formatting changes such as tidying line ends <= 79 characters, reformatting very wide ascii table as list table to control line widths, etc. Resolved conflict in _includes/data-networks-overview.rest Change-Id: I8a2a80f21d3630849900e85dc2495da1668648af Signed-off-by: Ron Stone <ronald.stone@windriver.com> Signed-off-by: Stone <ronald.stone@windriver.com>

========================================
|
|
Use IP Address Pools for Data Interfaces
|
|
========================================
|
|
|
|
You can create pools of IP addresses for use with data interfaces.
|
|
|
|
.. rubric:: |context|
|
|
|
|
As an alternative to manually adding static IP addresses to data interfaces for
|
|
use with VXLANs, you can define pools of IP addresses and associate them with
|
|
one or more data interfaces. Each pool consists of one or more contiguous
|
|
ranges of IPv4 or IPv6 addresses. When a data interface is associated with a
|
|
pool, its IP address is allocated from the pool. The allocation may be either
|
|
random or sequential, depending on the settings for the pool.
|
|
|
|
You can use the web administration interface or the CLI to create and manage
|
|
address pools. For information about using the CLI, see :ref:`Managing IP
|
|
Address Pools Using the CLI <managing-ip-address-pools-using-the-cli>`.
|
|
|
|
.. rubric:: |prereq|
|
|
|
|
To make interface changes, you must lock the compute node first.
|
|
|
|
.. rubric:: |proc|
|
|
|
|
#. Lock the compute node.
|
|
|
|
#. In the |prod-os| Web administration interface, open the System
|
|
Configuration page.
|
|
|
|
The System Configuration page is available from **Admin** \> **Platform**
|
|
\> **System Configuration** in the left-hand pane.
|
|
|
|
#. Select the **Address Pools** tab.
|
|
|
|
.. image:: figures/jow1445971002260.png
|
|
|
|
You can use the controls on the Address Pools page to create, update, or
|
|
delete address pools.
|
|
|
|
#. To create an address pool, click **Create Address Pool** and complete the
|
|
dialog box.
|
|
|
|
.. image:: figures/jow1445971475692.png
|
|
|
|
**Name**
|
|
A name used for selecting the pool during data interface setup.
|
|
|
|
**Network Address**
|
|
The subnet for the range \(for example, **192.168.1.0/24**\).
|
|
|
|
**Allocation Order**
|
|
The order for assigning addresses. You can select **Sequential** or
|
|
**Random** from the drop-down list.
|
|
|
|
**Address Range**
|
|
One or more ranges, where the start and end IP address of each range
|
|
is separated by a dash, and the ranges are separated by commas \(for
|
|
example, **192.168.1.10-192.168.1.20, 192.168.1.35-192.168.1.45**\).
|
|
If no range is specified, the full range is used.
|
|
|
|
.. rubric:: |postreq|
|
|
|
|
You can select an address pool by name when setting up the **IPv4 Addressing
|
|
Mode** or **IPv6 Addressing Mode** for a data interface.
|
