+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.
+  mirror_primary_address:
+    description:
+      - Specifies the primary IP address for the system to use to mirror
+        connections.
+  mirror_secondary_address:
+    description:
+      - Specifies the secondary IP address for the system to use to mirror
+        connections.
+  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.
+  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.
+    choices:
+      - yes
+      - no
+  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.
+  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.
+  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.
+notes:
+  - Requires the f5-sdk Python package on the host. This is as easy as pip
+    install f5-sdk.
+  - This module is primarily used as a component of configuring HA pairs of
+    BIG-IP devices.
+  - Requires BIG-IP >= 12.0.0
+requirements:
+  - f5-sdk >= 2.2.3
