f5networks.f5_modules.bigip_profile_tcp – Manage TCP profiles on a BIG-IP

Note

This plugin is part of the f5networks.f5_modules collection (version 1.13.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install f5networks.f5_modules.

To use it in a playbook, specify: f5networks.f5_modules.bigip_profile_tcp.

New in version 1.0.0: of f5networks.f5_modules

Synopsis

• Manage TCP profiles on a BIG-IP system. There are many TCP profiles, each with their own adjustments to the standard tcp profile. Users of this module should be aware that many of the available options have no module default. Instead, the default is assigned by the BIG-IP system itself which, in most cases, is acceptable.

Parameters

Parameter	Comments
delayed_acks boolean	When yes, the system sends fewer than one ACK segment per data segment received. When creating a new profile, if this parameter is not specified, the default is provided by the parent profile. Choices: no yes
early_retransmit boolean	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. Choices: no yes
idle_timeout string	Specifies the length of time 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 the TCP connection can remain idle before the system deletes it. When 0, or indefinite, specifies the system does not delete TCP connections regardless of how long they remain idle.
initial_congestion_window_size integer	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	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.
ip_tos_to_client string	Specifies the L3 Type of Service level the system inserts in TCP packets destined for clients. When pass-through, the IP ToS setting remains unchanged. When mimic, the system sets the ToS level of outgoing packets to the same ToS level of the most-recently received incoming packet. When set as a number, the number indicates the IP ToS setting the system inserts in the IP packet header. Valid number range is 0 - 255 inclusive. When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
nagle string	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. 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. Choices: auto enabled disabled
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	Device partition to manage resources on. Default: “Common”
provider dictionary added in 1.0.0 of f5networks.f5_modules	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.
no_f5_teem boolean	If yes, TEEM telemetry data is not sent to F5. You may omit this option by setting the environment variable F5_TELEMETRY_OFF. Previously used variable F5_TEEM is deprecated as its name was confusing. Choices: no ← (default) yes
password aliases: pass, pwd 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.
server string / required	The BIG-IP host. You may omit this option by setting the environment variable F5_SERVER.
server_port integer	The BIG-IP server port. You may omit this option by setting the environment variable F5_SERVER_PORT. Default: 443
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	Configures the transport connection to use when connecting to the remote device. Choices: rest ← (default)
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	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. Choices: no yes ← (default)
proxy_options boolean	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. Choices: no yes
state string	When present, ensures the profile exists. When absent, ensures the profile is removed. Choices: present ← (default) absent
syn_rto_base integer	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	Specifies 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. Choices: no yes
time_wait_timeout string added in 1.3.0 of f5networks.f5_modules	Specifies the number of milliseconds a connection is in the TIME-WAIT state before closing. When immediate, the system closes the connection immediately after the connection enters the TIME-WAIT state. When indefinite or 0, the system does not close TCP connections regardless of how long they remain in the TIME-WAIT state. The valid number range is from 0 to 600000 milliseconds. 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 f5networks.f5_modules.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.
