DESCRIPTION |
|
15 |
----------- |
|
16 |
|
|
17 |
The **gnt-network** command is used for network definition administration |
|
18 |
in the Ganeti system. |

COMMANDS |
|

-------- |
|

|
|

ADD |
|
24 |
~~~ |
|
25 |
|
|
26 |
| **add** |
|
27 |
| [--network=*NETWORK*] |
|
28 |
| [--gateway=*GATEWAY*] |
|
29 |
| [--reserved-ips=*RESERVEDIPS*] |
|
30 |
| [--network6=*NETWORK6*] |
|
31 |
| [--gateway6=*GATEWAY6*] |
|
32 |
| [--mac-prefix=*MACPREFIX*] |
|
33 |
| [--network-type=*NETWORKTYPE*] |
|
34 |
| {*network*} |
|
35 |
|
|
36 |
Creates a new network with the given name. The network will be unused |
|
37 |
initially. To connect it to a node group, use ``gnt-network connect``. |
|
38 |
``--network`` option is mandatory. All other are optional. |
|
39 |
|
|
40 |
The ``--network`` option allows you to specify the network in a CIDR notation. |
|
41 |
|
|
42 |
The ``--gateway`` option allows you to specify the default gateway for this |
|
43 |
network. |
|
44 |
|
|
45 |
The ``--network-type`` can be none, private or public. |
|
46 |
|
|
47 |
IPv6 semantics can be assigned to the network via the ``--network6`` and |
|
48 |
``--gateway6`` options. IP pool is meaningless for ipv6 so those two values |
|
49 |
can be used for EUI64 generation from a NIC's mac value. |
|

MODIFY |
|
52 |
~~~~~~ |
|
53 |
|
|

| {*network*} |
|
62 |
|
|
63 |
Modifies parameters from the network. |
|
64 |
|
|
65 |
Unable to modify network (ip range). Create a new network if you want to do |
|
66 |
so. All other options are documented in the **add** command above. |
|
67 |
|
|
68 |
REMOVE |
|
69 |
~~~~~~ |
|
70 |
|
|
71 |
| **remove** {*network*} |
|
72 |
|
|
73 |
Deletes the indicated network, which must be not connected to any node group. |
|
74 |
|
|

LIST |
|
76 |
~~~~ |
|
77 |
|
|
78 |
| **list** [--no-headers] [--separator=*SEPARATOR*] [-v] |
|
79 |
| [-o *[+]FIELD,...*] [network...] |
|
80 |
|
|
81 |
Lists all existing networks in the cluster. |
|
82 |
|
|
83 |
The ``--no-headers`` option will skip the initial header line. The |
|
84 |
``--separator`` option takes an argument which denotes what will be |
|
85 |
used between the output fields. Both these options are to help |
|
86 |
scripting. |
|
87 |
|
|
88 |
The ``-v`` option activates verbose mode, which changes the display of |
|
89 |
special field states (see **ganeti(7)**). |
|
90 |
|
|
91 |
The ``-o`` option takes a comma-separated list of output fields. |
|
92 |
If the value of the option starts with the character ``+``, the new |
|
93 |
fields will be added to the default list. This allows to quickly |
|
94 |
see the default list plus a few other fields, instead of retyping |
|
95 |
the entire list of fields. |
|

|
|
