Manage Data Interface Static IP Addresses Using the CLIΒΆ
If you prefer, you can create and manage static addresses for data interfaces using the CLI.
About this task
For more information about using static addresses for data interfaces, see Adding a Static IP Address to a Data Interface.
Prerequisites
To make interface changes, you must lock the compute node first.
Procedure
Lock the compute node.
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 compute node
- ifname
is the name of the interface
- ipv4mode
is either disabled or static
- ipv6mode
is either disabled or static
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 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 UUIDs 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 UUID of the address.
Unlock the compute node and wait for it to become available.
