module: bigip_device_connectivity
short_description: Manages device IP configuration settings for HA on a BIG-IP
description:
- Manages device IP configuration settings for HA on a BIG-IP. Each BIG-IP device
has synchronization and failover connectivity information (IP addresses) that
you define as part of HA pairing or clustering. This module allows you to configure
that information.
version_added: 2.5
options:
config_sync_ip:
description:
- Local IP address that the system uses for ConfigSync operations.
type: str
mirror_primary_address:
description:
- Specifies the primary IP address for the system to use to mirror
connections.
type: str
mirror_secondary_address:
description:
- Specifies the secondary IP address for the system to use to mirror
connections.
type: str
unicast_failover:
description:
- Desired addresses to use for failover operations. Options C(address)
and C(port) are supported with dictionary structure where C(address) is the
local IP address that the system uses for failover operations. Port
specifies the port that the system uses for failover operations. If C(port)
is not specified, the default value C(1026) will be used. If you are
specifying the (recommended) management IP address, use 'management-ip' in
the address field.
type: list
failover_multicast:
description:
- When C(yes), ensures that the Failover Multicast configuration is enabled
and if no further multicast configuration is provided, ensures that
C(multicast_interface), C(multicast_address) and C(multicast_port) are
the defaults specified in each option's description. When C(no), ensures
that Failover Multicast configuration is disabled.
type: bool
multicast_interface:
description:
- Interface over which the system sends multicast messages associated
with failover. When C(failover_multicast) is C(yes) and this option is
not provided, a default of C(eth0) will be used.
type: str
multicast_address:
description:
- IP address for the system to send multicast messages associated with
failover. When C(failover_multicast) is C(yes) and this option is not
provided, a default of C(224.0.0.245) will be used.
type: str
multicast_port:
description:
- Port for the system to send multicast messages associated with
failover. When C(failover_multicast) is C(yes) and this option is not
provided, a default of C(62960) will be used. This value must be between
0 and 65535.
type: int
cluster_mirroring:
description:
- Specifies whether mirroring occurs within the same cluster or between
different clusters on a multi-bladed system.
- This parameter is only supported on platforms that have multiple blades,
such as Viprion hardware. It is not supported on VE.
type: str
choices:
- between-clusters
- within-cluster
version_added: 2.7
notes:
- This module is primarily used as a component of configuring HA pairs of
BIG-IP devices.
- Requires BIG-IP >= 12.0.0
