module: bigip_profile_udp

|
short_description: Manage UDP profiles on a BIG-IP
|
|
description:
|
|
- Manage UDP profiles on a BIG-IP. Many of UDP profiles exist; each with their
|
|
own adjustments to the standard C(udp) profile. Users of this module should be aware
|
|
that many of the adjustable knobs have no module default. Instead, the default is
|
|
assigned by the BIG-IP system itself which, in most cases, is acceptable.
|
|
version_added: 2.6
|
|
options:
|
|
name:
|
|
description:
|
|
- Specifies the name of the profile.
|
|
required: True
|
|
parent:
|
|
description:
|
|
- Specifies the profile from which this profile inherits settings.
|
|
- When creating a new profile, if this parameter is not specified, the default
|
|
is the system-supplied C(udp) profile.
|
|
idle_timeout:
|
|
description:
|
|
- Specifies the length of time that a connection is idle (has no traffic) before
|
|
the connection is eligible for deletion.
|
|
- When creating a new profile, if this parameter is not specified, the remote
|
|
device will choose a default value appropriate for the profile, based on its
|
|
C(parent) profile.
|
|
- When a number is specified, indicates the number of seconds that the UDP
|
|
connection can remain idle before the system deletes it.
|
|
- When C(0), or C(indefinite), specifies that UDP connections can remain idle
|
|
indefinitely.
|
|
- When C(immediate), specifies that you do not want the UDP connection to
|
|
remain idle, and that it is therefore immediately eligible for deletion.
|
|
datagram_load_balancing:
|
|
description:
|
|
- Specifies, when C(yes), that the system load balances UDP traffic
|
|
packet-by-packet.
|
|
type: bool
|
|
partition:
|
|
description:
|
|
- Device partition to manage resources on.
|
|
default: Common
|
|
state:
|
|
description:
|
|
- When C(present), ensures that the profile exists.
|
|
- When C(absent), ensures the profile is removed.
|
|
default: present
|
|
choices:
|
|
- present
