gnt-network(8) Ganeti | Version @GANETI_VERSION@

================================================

Name

----

gnt-network - Ganeti network administration

Synopsis

--------

**gnt-network** {command} [arguments...]

DESCRIPTION

-----------

The **gnt-network** command is used for network definition

administration in the Ganeti system.

COMMANDS

--------

ADD

~~~

| **add**

| [--network=*NETWORK*]

| [--gateway=*GATEWAY*]

| [--add-reserved-ips=*RESERVEDIPS*]

| [--network6=*NETWORK6*]

| [--gateway6=*GATEWAY6*]

| [--mac-prefix=*MACPREFIX*]

| [--network-type=*NETWORKTYPE*]

| [--submit]

| {*network*}

Creates a new network with the given name. The network will be unused

initially. To connect it to a node group, use ``gnt-network connect``.

``--network`` option is mandatory. All other are optional.

The ``--network`` option allows you to specify the network in a CIDR

notation.

The ``--gateway`` option allows you to specify the default gateway for

this network.

The ``--network-type`` can be none, private or public.

IPv6 semantics can be assigned to the network via the ``--network6`` and

``--gateway6`` options. IP pool is meaningless for IPV6 so those two

values can be used for EUI64 generation from a NIC's MAC address.

See **ganeti**\(7) for a description of ``--submit`` and other common

options.

MODIFY

~~~~~~

| **modify**

| [--gateway=*GATEWAY*]

| [--add-reserved-ips=*RESERVEDIPS*]

| [--remove-reserved-ips=*RESERVEDIPS*]

| [--network6=*NETWORK6*]

| [--gateway6=*GATEWAY6*]

| [--mac-prefix=*MACPREFIX*]

| [--network-type=*NETWORKTYPE*]

| [--submit]

| {*network*}

Modifies parameters from the network.

Unable to modify network (IP address range). Create a new network if you

want to do so. All other options are documented in the **add** command

above.

See **ganeti**\(7) for a description of ``--submit`` and other common

options.

REMOVE

~~~~~~

| **remove** [--submit] {*network*}

Deletes the indicated network, which must be not connected to any node group.

See **ganeti**\(7) for a description of ``--submit`` and other common options.

LIST

~~~~

| **list** [--no-headers] [--separator=*SEPARATOR*] [-v]

| [-o *[+]FIELD,...*] [network...]

Lists all existing networks in the cluster. If no group names are given,

then all groups are included. Otherwise, only the named groups will be

listed.

The ``--no-headers`` option will skip the initial header line. The

``--separator`` option takes an argument which denotes what will be used

between the output fields. Both these options are to help scripting.

The ``-v`` option activates verbose mode, which changes the display of

special field states (see **ganeti**\(7)).

The ``-o`` option takes a comma-separated list of output fields. If the

value of the option starts with the character ``+``, the new fields will

be added to the default list. This allows to quickly see the default

list plus a few other fields, instead of retyping the entire list of

fields.

The available fields and their meaning are:

@QUERY_FIELDS_NETWORK@

LIST-FIELDS

~~~~~~~~~~~

**list-fields** [field...]

List available fields for networks.

INFO

~~~~

| **info** [network...]

Displays information about a given network.

CONNECT

~~~~~~~

| **connect** {*network*} {*mode*} {*link*} [*groups*...]

Connect a network to given node groups (all if not specified) with the

network parameters *mode* and *link*. Every network interface will

inherit those parameters if assigned in a network.

DISCONNECT

~~~~~~~~~~

| **disconnect** {*network*} [*groups*...]

Disconnect a network from given node groups (all if not specified). This

is possible only if no instance is using the network.

Tags

~~~~

ADD-TAGS

^^^^^^^^

**add-tags** [\--from *file*] {*networkname*} {*tag*...}

Add tags to the given network. If any of the tags contains invalid

characters, the entire operation will abort.

If the ``--from`` option is given, the list of tags will be extended

with the contents of that file (each line becomes a tag). In this case,

there is not need to pass tags on the command line (if you do, both

sources will be used). A file name of ``-`` will be interpreted as

stdin.

LIST-TAGS

^^^^^^^^^

**list-tags** {*networkname*}

List the tags of the given network.

REMOVE-TAGS

^^^^^^^^^^^

**remove-tags** [\--from *file*] {*networkname*} {*tag*...}

Remove tags from the given network. If any of the tags are not existing

on the network, the entire operation will abort.

If the ``--from`` option is given, the list of tags to be removed will

be extended with the contents of that file (each line becomes a tag). In

this case, there is not need to pass tags on the command line (if you

do, tags from both sources will be removed). A file name of ``-`` will

be interpreted as stdin.
