module: bigip_device_group
|
|
short_description: Manage device groups on a BIG-IP
|
|
description:
|
|
- Managing device groups allows you to create HA pairs and clusters
|
|
of BIG-IP devices. Usage of this module should be done in conjunction
|
|
with the C(bigip_configsync_actions) to sync configuration across
|
|
the pair or cluster if auto-sync is disabled.
|
|
version_added: "2.5"
|
|
options:
|
|
name:
|
|
description:
|
|
- Specifies the name of the device group.
|
|
required: True
|
|
type:
|
|
description:
|
|
- Specifies that the type of group. A C(sync-failover) device group
|
|
contains devices that synchronize their configuration data and fail
|
|
over to one another when a device becomes unavailable. A C(sync-only)
|
|
device group has no such failover. When creating a new device group,
|
|
this option will default to C(sync-only). This setting cannot be
|
|
changed once it has been set.
|
|
choices:
|
|
- sync-failover
|
|
- sync-only
|
|
description:
|
|
description:
|
|
- Description of the device group.
|
|
auto_sync:
|
|
description:
|
|
- Indicates whether configuration synchronization occurs manually or
|
|
automatically. When creating a new device group, this option will
|
|
default to C(false).
|
|
type: bool
|
|
save_on_auto_sync:
|
|
description:
|
|
- When performing an auto-sync, specifies whether the configuration
|
|
will be saved or not. If C(false), only the running configuration
|
|
will be changed on the device(s) being synced to. When creating a
|
|
new device group, this option will default to C(false).
|
|
type: bool
|
|
full_sync:
|
|
description:
|
|
- Specifies whether the system synchronizes the entire configuration
|
|
during synchronization operations. When C(false), the system performs
|
|
incremental synchronization operations, based on the cache size
|
|
specified in C(max_incremental_sync_size). Incremental configuration
|
|
synchronization is a mechanism for synchronizing a device-group's
|
|
configuration among its members, without requiring a full configuration
|
|
load for each configuration change. In order for this to work, all
|
|
devices in the device-group must initially agree on the configuration.
|
|
Typically this requires at least one full configuration load to each
|
|
device. When creating a new device group, this option will default
|
|
to C(false).
|
|
type: bool
|
|
max_incremental_sync_size:
|
|
description:
|
|
- Specifies the size of the changes cache for incremental sync. For example,
|
|
using the default, if you make more than 1024 KB worth of incremental
|
|
changes, the system performs a full synchronization operation. Using
|
|
incremental synchronization operations can reduce the per-device sync/load
|
|
time for configuration changes. This setting is relevant only when
|
|
C(full_sync) is C(false).
|
|
state:
|
|
description:
|
|
- When C(state) is C(present), ensures the device group exists.
|
|
- When C(state) is C(absent), ensures that the device group is removed.
|
|
choices:
|
|
- present
|
|
- absent
|
|
notes:
|
|
- This module is primarily used as a component of configuring HA pairs of
|
|
BIG-IP devices.
|
|
- Requires BIG-IP >= 12.1.x.
