|
||||
description:
|
||||
- Manage TCP profiles on a BIG-IP. There are a variety of TCP profiles, each with their
|
||||
own adjustments to the standard C(tcp) 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(tcp) 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 TCP
|
||||
connection can remain idle before the system deletes it.
|
||||
- When C(0), or C(indefinite), specifies that the system does not delete TCP connections
|
||||
regardless of how long they remain idle.
|
||||
partition:
|

description:
|

- Device partition to manage resources on.

description:

- When C(present), ensures that the profile exists.
