bigip_profile_tcp – Manage TCP profiles on a BIG-IP

New in version 2.6.


Synopsis

  • Manage TCP profiles on a BIG-IP. Many TCP profiles; each with their own adjustments to the standard 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.

Parameters

Parameter Choices/Defaults Comments

early_retransmit

boolean

added in 2.9

  • no
  • yes

When yes the system uses early fast retransmits to reduce the recovery time for connections that are receive-buffer or user-data limited.

When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.

idle_timeout

string

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 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 0, or indefinite, specifies that the system does not delete TCP connections regardless of how long they remain idle.

initial_congestion_window_size

integer

added in 2.9

Specifies the initial congestion window size for connections to this destination. The actual window size is this value multiplied by the MSS for the same connection.

When set to 0 the system uses the values specified in RFC2414.

The valid value range is 0 - 16 inclusive.

When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.

initial_receive_window_size

integer

added in 2.9

Specifies the initial receive window size for connections to this destination. The actual window size is this value multiplied by the MSS for the same connection.

When set to 0 the system uses the Slow Start value.

The valid value range is 0 - 16 inclusive.

When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.

nagle

string

added in 2.9

  • auto
  • enabled
  • disabled

When enabled the system applies Nagle's algorithm to reduce the number of short segments on the network.

When auto, the use of Nagle's algorithm is decided based on network conditions.

Note that for interactive protocols such as Telnet, rlogin, or SSH, F5 recommends disabling this setting on high-latency networks, to improve application responsiveness.

When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.

name

string / required

Specifies the name of the profile.

parent

string

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 tcp profile.

partition

string

Default:

"Common"

Device partition to manage resources on.

provider

dictionary

added in 2.5

A dict object containing connection details.

auth_provider

string

Configures the auth provider for to obtain authentication tokens from the remote device.

This option is really used when working with BIG-IQ devices.

password

string / required

The password for the user account used to connect to the BIG-IP.

You may omit this option by setting the environment variable F5_PASSWORD.


aliases: pass, pwd

server

string / required

The BIG-IP host.

You may omit this option by setting the environment variable F5_SERVER.

server_port

integer

Default:

443

The BIG-IP server port.

You may omit this option by setting the environment variable F5_SERVER_PORT.

ssh_keyfile

path

Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports.

You may omit this option by setting the environment variable ANSIBLE_NET_SSH_KEYFILE.

timeout

integer

Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.

transport

string

  • cli
  • rest

Configures the transport connection to use when connecting to the remote device.

user

string / required

The username to connect to the BIG-IP with. This user must have administrative privileges on the device.

You may omit this option by setting the environment variable F5_USER.

validate_certs

boolean

  • no
  • yes

If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.

You may omit this option by setting the environment variable F5_VALIDATE_CERTS.

proxy_options

boolean

added in 2.9

  • no
  • yes

When yes the system advertises an option, such as a time-stamp to the server only if it was negotiated with the client.

When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.

state

string

  • present

  • absent

When present, ensures that the profile exists.

When absent, ensures the profile is removed.

syn_rto_base

integer

added in 2.9

Specifies the initial RTO Retransmission TimeOut base multiplier for SYN retransmission, in milliseconds.

This value is modified by the exponential backoff table to select the interval for subsequent retransmissions.

The valid value range is 0 - 5000 inclusive.

When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.

time_wait_recycle

boolean

added in 2.7

  • no
  • yes

Specifies that connections in a TIME-WAIT state are reused, if a SYN packet, indicating a request for a new connection, is received.

When no, connections in a TIME-WAIT state remain unused for a specified length of time.

When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.



Notes

Note

  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.
  • Requires BIG-IP software version >= 12.
  • The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
