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.

Manage Data Interface Static IP Addresses Using the CLI

If you prefer, you can create and manage static addresses for data interfaces using the .

For more information about using static addresses for data interfaces, see Adding a Static IP Address to a Data Interface <adding-a-static-ip-address-to-a-data-interface>.

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

  1. Lock the compute node.

  2. Set the interface to support an IPv4 or IPv6 address, or both.

    ~(keystone_admin)]$ system host-if-modify <node> <ifname> --ipv4-mode=<ipv4mode> --ipv6-mode=<ipv6mode>

    where

    node

    is the name or of the compute node

    ifname

    is the name of the interface

    ipv4mode

    is either disabled or static

    ipv6mode

    is either disabled or static

  3. Add an IPv4 or IPv6 address to the interface.

    ~(keystone_admin)]$ system host-addr-add <node> <ifname> <ip_address> <prefix>

    where

    node

    is the name or of the compute node

    ifname

    is the name of the interface

    ip_address

    is an IPv4 or IPv6 address

    prefix

    is the netmask length for the address

    To delete an address, use the following commands:

    ~(keystone_admin)]$ system host-addr-list <hostname/ID>

    This displays the of existing addresses, as shown in this example below.

    ~(keystone_admin)]$ system host-addr-list compute-0
+-----------------------+--------+------------------------+--------+
| uuid                  | ifname | address                | prefix |
+-----------------------+--------+------------------------+--------+
| 290629f6-41e5-48d9... | ae0    | 2605:6400:2:fed5:22... | 112    |
| 5de0e0bf-21fc-4532... | ae0    | 2605:6400:2:fed5:22... | 122    |
| e78923d7-3ccf-4332... | ae0    | 192.168.61.70          | 27     |
+-----------------------+--------+------------------------+--------+
    ~(keystone_admin)]$ system host-addr-delete <uuid>

    where uuid is the of the address.

  4. Unlock the compute node and wait for it to become available.
