### enum NMCapability

NMCapability names the numbers in the Capabilities property. Capabilities are positive numbers. They are part of stable API and a certain capability number is guaranteed not to change.

The range 0x7000 - 0x7FFF of capabilities is guaranteed not to be used by upstream NetworkManager. It could thus be used for downstream extensions.

#### Members

NM_CAPABILITY_TEAM | Teams can be managed. This means the team device plugin is loaded. |
NM_CAPABILITY_OVS | OpenVSwitch can be managed. This means the OVS device plugin is loaded. Since: 1.24. |

### enum NMState

NMState values indicate the current overall networking state.

#### Members

NM_STATE_UNKNOWN | Networking state is unknown. This indicates a daemon error that makes it unable to reasonably assess the state. In such event the applications are expected to assume Internet connectivity might be present and not disable controls that require network access. The graphical shells may hide the network accessibility indicator altogether since no meaningful status indication can be provided. |
NM_STATE_ASLEEP | Networking is not enabled, the system is being suspended or resumed from suspend. |
NM_STATE_DISCONNECTED | There is no active network connection. The graphical shell should indicate no network connectivity and the applications should not attempt to access the network. |
NM_STATE_DISCONNECTING | Network connections are being cleaned up. The applications should tear down their network sessions. |
NM_STATE_CONNECTING | A network connection is being started The graphical shell should indicate the network is being connected while the applications should still make no attempts to connect the network. |
NM_STATE_CONNECTED_LOCAL | There is only local IPv4 and/or IPv6 connectivity, but no default route to access the Internet. The graphical shell should indicate no network connectivity. |
NM_STATE_CONNECTED_SITE | There is only site-wide IPv4 and/or IPv6 connectivity. This means a default route is available, but the Internet connectivity check (see "Connectivity" property) did not succeed. The graphical shell should indicate limited network connectivity. |
NM_STATE_CONNECTED_GLOBAL | There is global IPv4 and/or IPv6 Internet connectivity This means the Internet connectivity check succeeded, the graphical shell should indicate full network connectivity. |

### enum NMConnectivityState

#### Members

NM_CONNECTIVITY_UNKNOWN | Network connectivity is unknown. This means the connectivity checks are disabled (e.g. on server installations) or has not run yet. The graphical shell should assume the Internet connection might be available and not present a captive portal window. |
NM_CONNECTIVITY_NONE | The host is not connected to any network. There's no active connection that contains a default route to the internet and thus it makes no sense to even attempt a connectivity check. The graphical shell should use this state to indicate the network connection is unavailable. |
NM_CONNECTIVITY_PORTAL | The Internet connection is hijacked by a captive portal gateway. The graphical shell may open a sandboxed web browser window (because the captive portals typically attempt a man-in-the-middle attacks against the https connections) for the purpose of authenticating to a gateway and retrigger the connectivity check with `CheckConnectivity()` when the browser window is dismissed. |
NM_CONNECTIVITY_LIMITED | The host is connected to a network, does not appear to be able to reach the full Internet, but a captive portal has not been detected. |
NM_CONNECTIVITY_FULL | The host is connected to a network, and appears to be able to reach the full Internet. |

### enum NMMetered

The NMMetered enum has two different purposes: one is to configure "connection.metered" setting of a connection profile in NMSettingConnection, and the other is to express the actual metered state of the NMDevice at a given moment.

For the connection profile only NM_METERED_UNKNOWN, NM_METERED_NO and NM_METERED_YES are allowed.

The device's metered state at runtime is determined by the profile which is currently active. If the profile explicitly specifies NM_METERED_NO or NM_METERED_YES, then the device's metered state is as such. If the connection profile leaves it undecided at NM_METERED_UNKNOWN (the default), then NetworkManager tries to guess the metered state, for example based on the device type or on DHCP options (like Android devices exposing a "ANDROID_METERED" DHCP vendor option). This then leads to either NM_METERED_GUESS_NO or NM_METERED_GUESS_YES.

Most applications probably should treat the runtime state NM_METERED_GUESS_YES like NM_METERED_YES, and all other states as not metered.

Note that the per-device metered states are then combined to a global metered state. This is basically the metered state of the device with the best default route. However, that generalization of a global metered state may not be correct if the default routes for IPv4 and IPv6 are on different devices, or if policy routing is configured. In general, the global metered state tries to express whether the traffic is likely metered, but since that depends on the traffic itself, there is not one answer in all cases. Hence, an application may want to consider the per-device's metered states.

#### Members

NM_METERED_UNKNOWN | The metered status is unknown |
NM_METERED_YES | Metered, the value was explicitly configured |
NM_METERED_NO | Not metered, the value was explicitly configured |

### enum NMCheckpointCreateFlags

The flags for CheckpointCreate call

#### Members

NM_CHECKPOINT_CREATE_FLAG_NONE | no flags |
NM_CHECKPOINT_CREATE_FLAG_DESTROY_ALL | when creating a new checkpoint, destroy all existing ones. |
NM_CHECKPOINT_CREATE_FLAG_DELETE_NEW_CONNECTIONS | upon rollback, delete any new connection added after the checkpoint. Since: 1.6. |
NM_CHECKPOINT_CREATE_FLAG_DISCONNECT_NEW_DEVICES | upon rollback, disconnect any new device appeared after the checkpoint. Since: 1.6. |
NM_CHECKPOINT_CREATE_FLAG_ALLOW_OVERLAPPING | by default, creating a checkpoint fails if there are already existing checkoints that reference the same devices. With this flag, creation of such checkpoints is allowed, however, if an older checkpoint that references overlapping devices gets rolled back, it will automatically destroy this checkpoint during rollback. This allows to create several overlapping checkpoints in parallel, and rollback to them at will. With the special case that rolling back to an older checkpoint will invalidate all overlapping younger checkpoints. This opts-in that the checkpoint can be automatically destroyed by the rollback of an older checkpoint. Since: 1.12. |
NM_CHECKPOINT_CREATE_FLAG_NO_PRESERVE_EXTERNAL_PORTS | during rollback, by default externally added ports attached to bridge devices are preserved. With this flag, the rollback detaches all external ports. This only has an effect for bridge ports. Before 1.38, this was the default behavior. Since: 1.38. |

Since: 1.4 (gi flags generated since 1.12)

### enum NMSettingsConnectionFlags

Flags describing the current activation state.

#### Members

NM_SETTINGS_CONNECTION_FLAG_NONE | an alias for numeric zero, no flags set. |
NM_SETTINGS_CONNECTION_FLAG_UNSAVED | the connection is not saved to disk. That either means, that the connection is in-memory only and currently is not backed by a file. Or, that the connection is backed by a file, but has modifications in-memory that were not persisted to disk. |
NM_SETTINGS_CONNECTION_FLAG_NM_GENERATED | A connection is "nm-generated" if it was generated by NetworkManger. If the connection gets modified or saved by the user, the flag gets cleared. A nm-generated is also unsaved and has no backing file as it is in-memory only. |
NM_SETTINGS_CONNECTION_FLAG_VOLATILE | The connection will be deleted when it disconnects. That is for in-memory connections (unsaved), which are currently active but deleted on disconnect. Volatile connections are always unsaved, but they are also no backing file on disk and are entirely in-memory only. |
NM_SETTINGS_CONNECTION_FLAG_EXTERNAL | the profile was generated to represent an external configuration of a networking device. Since: 1.26. |

Since: 1.12

### enum NMActivationStateFlags

Flags describing the current activation state.

#### Members

NM_ACTIVATION_STATE_FLAG_NONE | an alias for numeric zero, no flags set. |
NM_ACTIVATION_STATE_FLAG_IS_MASTER | the device is a master. |
NM_ACTIVATION_STATE_FLAG_IS_SLAVE | the device is a slave. |
NM_ACTIVATION_STATE_FLAG_LAYER2_READY | layer2 is activated and ready. |
NM_ACTIVATION_STATE_FLAG_IP4_READY | IPv4 setting is completed. |
NM_ACTIVATION_STATE_FLAG_IP6_READY | IPv6 setting is completed. |
NM_ACTIVATION_STATE_FLAG_MASTER_HAS_SLAVES | The master has any slave devices attached. This only makes sense if the device is a master. |
NM_ACTIVATION_STATE_FLAG_LIFETIME_BOUND_TO_PROFILE_VISIBILITY | the lifetime of the activation is bound to the visibility of the connection profile, which in turn depends on "connection.permissions" and whether a session for the user exists. Since: 1.16. |
NM_ACTIVATION_STATE_FLAG_EXTERNAL | the active connection was generated to represent an external configuration of a networking device. Since: 1.26. |

Since: 1.10

### enum NMSettingsAddConnection2Flags

Numeric flags for the "flags" argument of `AddConnection2()` D-Bus API.

#### Members

NM_SETTINGS_ADD_CONNECTION2_FLAG_NONE | an alias for numeric zero, no flags set. |
NM_SETTINGS_ADD_CONNECTION2_FLAG_TO_DISK | to persist the connection to disk. |
NM_SETTINGS_ADD_CONNECTION2_FLAG_IN_MEMORY | to make the connection in-memory only. |
NM_SETTINGS_ADD_CONNECTION2_FLAG_BLOCK_AUTOCONNECT | usually, when the connection has autoconnect enabled and gets added, it becomes eligible to autoconnect right away. Setting this flag, disables autoconnect until the connection is manually activated. |

Since: 1.20

### enum NMSettingsUpdate2Flags

#### Members

NM_SETTINGS_UPDATE2_FLAG_NONE | an alias for numeric zero, no flags set. |
NM_SETTINGS_UPDATE2_FLAG_TO_DISK | to persist the connection to disk. |
NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY | makes the profile in-memory. Note that such profiles are stored in keyfile format under /run. If the file is already in-memory, the file in /run is updated in-place. Otherwise, the previous storage for the profile is left unchanged on disk, and the in-memory copy shadows it. Note that the original filename of the previous persistent storage (if any) is remembered. That means, when later persisting the profile again to disk, the file on disk will be overwritten again. Likewise, when finally deleting the profile, both the storage from /run and persistent storage are deleted (or if the persistent storage does not allow deletion, and nmmeta file is written to mark the UUID as deleted). |
NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY_DETACHED | this is almost the same as `NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY`, with one difference: when later deleting the profile, the original profile will not be deleted. Instead a nmmeta file is written to /run to indicate that the profile is gone. Note that if such a nmmeta tombstone file exists and hides a file in persistent storage, then when re-adding the profile with the same UUID, then the original storage is taken over again. |
NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY_ONLY | this is like `NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY`, but if the connection has a corresponding file on persistent storage, the file will be deleted right away. If the profile is later again persisted to disk, a new, unused filename will be chosen. |
NM_SETTINGS_UPDATE2_FLAG_VOLATILE | This can be specified with either `NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY`, `NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY_DETACHED` or `NM_SETTINGS_UPDATE2_FLAG_IN_MEMORY_ONLY`. After making the connection in-memory only, the connection is marked as volatile. That means, if the connection is currently not active it will be deleted right away. Otherwise, it is marked to for deletion once the connection deactivates. A volatile connection cannot autoactivate again (because it's about to be deleted), but a manual activation will clear the volatile flag. |
NM_SETTINGS_UPDATE2_FLAG_BLOCK_AUTOCONNECT | usually, when the connection has autoconnect enabled and is modified, it becomes eligible to autoconnect right away. Setting this flag, disables autoconnect until the connection is manually activated. |
NM_SETTINGS_UPDATE2_FLAG_NO_REAPPLY | when a profile gets modified that is currently active, then these changes don't take effect for the active device unless the profile gets reactivated or the configuration reapplied. There are two exceptions: by default "connection.zone" and "connection.metered" properties take effect immediately. Specify this flag to prevent these properties to take effect, so that the change is restricted to modify the profile. Since: 1.20. |

Since: 1.12

### enum NMTernary

#### Members

NM_TERNARY_DEFAULT | use the globally-configured default value. |

### enum NMManagerReloadFlags

Flags for the manager `Reload()` call.

#### Members

NM_MANAGER_RELOAD_FLAG_NONE | an alias for numeric zero, no flags set. This reloads everything that is supported and is identical to a SIGHUP. |
NM_MANAGER_RELOAD_FLAG_CONF | reload the NetworkManager.conf configuration from disk. Note that this does not include connections, which can be reloaded via Setting's `ReloadConnections()`. |
NM_MANAGER_RELOAD_FLAG_DNS_RC | update DNS configuration, which usually involves writing /etc/resolv.conf anew. |
NM_MANAGER_RELOAD_FLAG_DNS_FULL | means to restart the DNS plugin. This is for example useful when using dnsmasq plugin, which uses additional configuration in /etc/NetworkManager/dnsmasq.d. If you edit those files, you can restart the DNS plugin. This action shortly interrupts name resolution. |
NM_MANAGER_RELOAD_FLAG_ALL | all flags. |
