Parameters

Parameter Choices/Defaults Comments
address_translation
boolean
added in 2.6
    Choices:
  • no
  • yes
Specifies, when enabled, that the system translates the address of the virtual server.
When disabled, specifies that the system uses the address without translation.
This option is useful when the system is load balancing devices that have the same IP address.
When creating a new virtual server, the default is enabled.
clone_pools
list
added in 2.8
Specifies a pool or list of pools that the virtual server uses to replicate either client-side or server-side traffic.
Typically this option is used for intrusion detection.
context
string
    Choices:
  • clientside
  • serverside
The context option for a clone pool to replicate either client-side or server-side traffic.
pool_name
string / required
The pool name to which the server replicates the traffic.
Only pools created on Common partition or on the same partition as the virtual server can be used.
Referencing pool on common partition needs to be done in the full path format, for example, /Common/pool_name.
default_persistence_profile
string
Default Profile which manages the session persistence.
If you want to remove the existing default persistence profile, specify an empty value; "". See the documentation for an example.
When type is dhcp, this parameter will be ignored.
description
string
Virtual server description.
destination
string
Destination IP of the virtual server.
Required when state is present and virtual server does not exist.
When type is internal, this parameter is ignored. For all other types, it is required.
Destination can also be specified as a name for an existing Virtual Address.

aliases: address, ip
disabled_vlans
list
added in 2.5
List of VLANs to be disabled. If the partition is not specified in the VLAN, then the partition option of this module will be used.
This parameter is mutually exclusive with the enabled_vlans parameters.
enabled_vlans
list
added in 2.2
List of VLANs to be enabled. When a VLAN named all is used, all VLANs will be allowed. VLANs can be specified with or without the leading partition. If the partition is not specified in the VLAN, then the partition option of this module will be used.
This parameter is mutually exclusive with the disabled_vlans parameter.
fallback_persistence_profile
string
added in 2.3
Specifies the persistence profile you want the system to use if it cannot use the specified default persistence profile.
If you want to remove the existing fallback persistence profile, specify an empty value; "". See the documentation for an example.
When type is dhcp, this parameter will be ignored.
firewall_enforced_policy
string
added in 2.6
Applies the specify AFM policy to the virtual in an enforcing way.
When creating a new virtual, if this parameter is not specified, the enforced policy is disabled.
firewall_staged_policy
string
added in 2.6
Applies the specify AFM policy to the virtual in an enforcing way.
A staged policy shows the results of the policy rules in the log, while not actually applying the rules to traffic.
When creating a new virtual, if this parameter is not specified, the staged policy is disabled.
insert_metadata
boolean
added in 2.8
    Choices:
  • no
  • yes ←
When set to no it will not set metadata on the device.
Currently there is a limitation that non-admin users cannot set metadata on the object, despite being able to create and modify virtual server objects, setting this option to no will allow such users to utilize this module to manage Virtual Server objects on the device.
ip_intelligence_policy
string
added in 2.8
Specifies the IP intelligence policy applied to the virtual server.
This parameter requires that a valid BIG-IP security module such as ASM or AFM be provisioned.

When type is reject, this parameter will be ignored.
When type is internal, this parameter will be ignored.

aliases: all_rules
mask
string
added in 2.8
Specifies the destination address network mask. This parameter will work with IPv4 and IPv6 type of addresses.
This is an optional parameter which can be specified when creating or updating virtual server.
If destination is set in CIDR notation format and mask is provided the mask parameter takes precedence.
If catchall destination is specified, i.e. 0.0.0.0 for IPv4 :: for IPv6, mask parameter is set to any or any6 respectively.
When the destination is provided not in CIDR notation and mask is not specified, 255.255.255.255 or ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff is set for IPv4 and IPv6 addresses respectively.
When destination is provided in CIDR notation format and mask is not specified the mask parameter is inferred from destination.
When destination is provided as Virtual Address name, and mask is not specified, the mask will be None allowing device set it with its internal defaults.
metadata
raw
added in 2.5
Arbitrary key/value pairs that you can attach to a virtual server. This is useful in situations where you might want to annotate a virtual to be managed by Ansible.
Key names will be stored as strings; this includes names that are numbers.
Values for all of the keys will be stored as strings; this includes values that are numbers.
Data will be persisted, not ephemeral.
mirror
boolean
added in 2.8

When type is reject, this parameter will be ignored.
When type is internal, this parameter will be ignored.

aliases: all_policies
pool
string
Default pool for the virtual server.
If you want to remove the existing pool, specify an empty value; "". See the documentation for an example.
When creating a new virtual server, and type is stateless, this parameter is required.
If type is stateless, the pool that is used must not have any members which define a rate_limit.
port
string
Port of the virtual server. Required when state is present and virtual server does not exist.
If you do not want to specify a particular port, use the value 0. The result is that the virtual server will listen on any port.
When type is dhcp, this module will force the port parameter to be 67.
When type is internal, this module will force the port parameter to be 0.
In addition to specifying a port number, a select number of service names may also be provided.
The string ftp may be substituted for for port 21.
The string http may be substituted for for port 80.
The string https may be substituted for for port 443.
The string telnet may be substituted for for port 23.

port_translation
boolean
added in 2.6
    Choices:
  • no
  • yes
Specifies, when enabled, that the system translates the port of the virtual server.
When disabled, specifies that the system uses the port without translation. Turning off port translation for a virtual server is useful if you want to use the virtual server to load balance connections to any service.
When creating a new virtual server, the default is enabled.
profiles
list
List of profiles (HTTP, ClientSSL, ServerSSL, etc) to apply to both sides of the connection (client-side and server-side).
If you only want to apply a particular profile to the client-side of the connection, specify client-side for the profile's context.
If you only want to apply a particular profile to the server-side of the connection, specify server-side for the profile's context.
If context is not provided, it will default to all.
If you want to remove a profile from the list of profiles currently active on the virtual, then simply remove it from the profiles list. See examples for an illustration of this.
If you want to add a profile to the list of profiles currently active on the virtual, then simply add it to the profiles list. See examples for an illustration of this.
Profiles matter. This module will fail to configure a BIG-IP if you mix up your profiles, or, if you attempt to set an IP protocol which your current, or new, profiles do not support. Both this module, and BIG-IP, will tell you when you are wrong, with an error resembling lists profiles incompatible with its protocol.
If you are unsure what correct profile combinations are, then have a BIG-IP available to you in which you can make changes and copy what the correct combinations are.

When type is reject, this parameter will be ignored.
When type is internal, this parameter will be ignored.
The name of a SNAT pool (eg "/Common/snat_pool_name") can be specified to enable SNAT with the specific pool.
To remove SNAT, specify the word none.
To specify automap, use the word automap.
source
string
added in 2.5
Specifies an IP address or network from which the virtual server accepts traffic.
The virtual server accepts clients only from one of these IP addresses.
For this setting to function effectively, specify a value other than 0.0.0.0/0 or ::/0 (that is, any/0, any6/0).
In order to maximize utility of this setting, specify the most specific address prefixes covering all customer addresses and no others.
Specify the IP address in Classless Inter-Domain Routing (CIDR) format; address/prefix, where the prefix length is in bits. For example, for IPv4, 10.0.0.1/32 or 10.0.0.0/24, and for IPv6, ffe1::0020/64 or 2001:ed8:77b5:2:10:10:100:42/64.
source_port
string
added in 2.8
    Choices:
  • preserve
  • preserve-strict
  • change
Specifies whether the system preserves the source port of the connection.
When creating a new virtual server, if this parameter is not specified, the default is preserve.
state
string
    Choices:
  • present ←
  • absent
  • enabled
  • disabled
The virtual server state. If absent, delete the virtual server if it exists. present creates the virtual server and enable it. If enabled, enable the virtual server if it exists. If disabled, create the virtual server if needed, and set state to disabled.
type
string
added in 2.6
    Choices:
  • standard ←
  • forwarding-l2
  • forwarding-ip
  • performance-http
  • performance-l4
  • stateless
  • reject
  • dhcp
  • internal
  • message-routing
Specifies the network service provided by this virtual server.
When creating a new virtual server, if this parameter is not provided, the default will be standard.
This value cannot be changed after it is set.
When standard, specifies a virtual server that directs client traffic to a load balancing pool and is the most basic type of virtual server. When you first create the virtual server, you assign an existing default pool to it. From then on, the virtual server automatically directs traffic to that default pool.
When forwarding-l2, specifies a virtual server that shares the same IP address as a node in an associated VLAN.
When forwarding-ip, specifies a virtual server like other virtual servers, except that the virtual server has no pool members to load balance. The virtual server simply forwards the packet directly to the destination IP address specified in the client request.
When performance-http, specifies a virtual server with which you associate a Fast HTTP profile. Together, the virtual server and profile increase the speed at which the virtual server processes HTTP requests.
When performance-l4, specifies a virtual server with which you associate a Fast L4 profile. Together, the virtual server and profile increase the speed at which the virtual server processes layer 4 requests.
When stateless, specifies a virtual server that accepts traffic matching the virtual server address and load balances the packet to the pool members without attempting to match the packet to a pre-existing connection in the connection table. New connections are immediately removed from the connection table. This addresses the requirement for one-way UDP traffic that needs to be processed at very high throughput levels, for example, load balancing syslog traffic to a pool of syslog servers. Stateless virtual servers are not suitable for processing traffic that requires stateful tracking, such as TCP traffic. Stateless virtual servers do not support iRules, persistence, connection mirroring, rateshaping, or SNAT automap.
When reject, specifies that the BIG-IP system rejects any traffic destined for the virtual server IP address.
When dhcp, specifies a virtual server that relays Dynamic Host Control Protocol (DHCP) client requests for an IP address to one or more DHCP servers, and provides DHCP server responses with an available IP address for the client.
When internal, specifies a virtual server that supports modification of HTTP requests and responses. Internal virtual servers enable usage of ICAP (Internet Content Adaptation Protocol) servers to modify HTTP requests and responses by creating and applying an ICAP profile and adding Request Adapt or Response Adapt profiles to the virtual server.
When message-routing, specifies a virtual server that uses a SIP application protocol and functions in accordance with a SIP session profile and SIP router profile.
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
added in 2.0
    Choices:
  • 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.

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.
