Manage Data Interface Static IP Addresses Using the CLI

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

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 worker node first.

1. Lock the worker 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 UUID of the worker 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 UUID of the worker 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 UUIDs of existing addresses, as shown in this example below.

   ~(keystone_admin)]$ system host-addr-list worker-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 UUID of the address.

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