module: bigip_profile_oneconnect
short_description: Manage OneConnect profiles on a BIG-IP
description:
- Manage OneConnect profiles on a BIG-IP.
version_added: 2.7
options:
name:
description:
- Specifies the name of the OneConnect 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(oneconnect) profile.
source_mask:
description:
- Specifies a value that the system applies to the source address to determine
its eligibility for reuse.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
- The system applies the value of this setting to the server-side source address to
determine its eligibility for reuse.
- A mask of C(0) causes the system to share reused connections across all source
addresses. A host mask of C(32) causes the system to share only those reused
connections originating from the same source address.
- When you are using a SNAT or SNAT pool, the server-side source address is
translated first and then the OneConnect mask is applied to the translated address.
description:
description:
- Description of the profile.
maximum_size:
description:
- Specifies the maximum number of connections that the system holds in the
connection reuse pool.
- If the pool is already full, then a server-side connection closes after the
response is completed.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
maximum_age:
description:
- Specifies the maximum number of seconds allowed for a connection in the connection
reuse pool.
- For any connection with an age higher than this value, the system removes that
connection from the re-use pool.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
maximum_reuse:
description:
- Specifies the maximum number of times that a server-side connection can be reused.
- When creating a new profile, if this parameter is not specified, the
default is provided by the parent profile.
idle_timeout_override:
description:
- Specifies the number of seconds that a connection is idle before the connection
flow is eligible for deletion.
- When creating a new profile, if this parameter is not specified, the default
is provided by the parent profile.
- You may specify a number of seconds for the timeout override.
- When C(disabled), specifies that there is no timeout override for the connection.
- When C(indefinite), Specifies that a connection may be idle with no timeout
override.
limit_type:
description:
- When C(none), simultaneous in-flight requests and responses over TCP connections
to a pool member are counted toward the limit. This is the historical behavior.
- When C(idle), idle connections will be dropped as the TCP connection limit is
reached. For short intervals, during the overlap of the idle connection being
dropped and the new connection being established, the TCP connection limit may
be exceeded.
- When C(strict), the TCP connection limit is honored with no exceptions. This means
that idle connections will prevent new TCP connections from being made until
they expire, even if they could otherwise be reused.
- C(strict) is not a recommended configuration except in very special cases with
short expiration timeouts.
- When creating a new profile, if this parameter is not specified, the default
is provided by the parent profile.
choices:
- none
- idle
- strict
share_pools:
description:
- Indicates that connections may be shared not only within a virtual server, but
also among similar virtual servers
- When C(yes), all virtual servers that use the same OneConnect and other internal
network profiles can share connections.
- When creating a new profile, if this parameter is not specified, the default
is provided by the parent profile.
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
- absent
