Use IP Address Pools for Data Interfaces

You can create pools of IP addresses for use with data interfaces.

As an alternative to manually adding static IP addresses to data interfaces for use with , 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 or the to create and manage address pools. For information about using the , see Managing IP Address Pools Using the CLI <managing-ip-address-pools-using-the-cli>.

To make interface changes, you must lock the compute node first.

  1. Lock the compute node.

  2. In the Web administration interface, open the System Configuration page.

    The System Configuration page is available from Admin > Platform > System Configuration in the left-hand pane.

  3. Select the Address Pools tab.

    You can use the controls on the Address Pools page to create, update, or delete address pools.

  4. To create an address pool, click Create Address Pool and complete the dialog box.

    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.

You can select an address pool by name when setting up the IPv4 Addressing Mode or IPv6 Addressing Mode for a data interface.
