Synopsis

  • Manage VLANs on a BIG-IP system

Parameters

Parameter

Comments

cmp_hash

string

Specifies how the traffic on the VLAN is disaggregated. The value you select determines the traffic disaggregation method. You can choose to disaggregate traffic based on source-address (the source IP address), destination-address (destination IP address), or default, which specifies the default CMP hash uses L4 ports.

When creating a new VLAN, if this parameter is not specified, the default is default.

Choices:

  • default

  • destination-address

  • source-address

  • dst-ip

  • src-ip

  • dest

  • destination

  • source

  • dst

  • src

dag_round_robin

boolean

Specifies whether some of the stateless traffic on the VLAN should be disaggregated in a round-robin order instead of using a static hash. The stateless traffic includes non-IP L2 traffic, ICMP, some UDP protocols, and so on.

When creating a new VLAN, if this parameter is not specified, the default is (no).

Choices:

  • no

  • yes

dag_tunnel

string

Specifies how the disaggregator (DAG) distributes received tunnel-encapsulated packets to TMM instances. Select inner to distribute packets based on information in inner headers. Select outer to distribute packets based on information in outer headers without inspecting inner headers.

When creating a new VLAN, if this parameter is not specified, the default is outer.

This parameter is not supported on Virtual Editions (VEs) of BIG-IP.

Choices:

  • inner

  • outer

description

string

The description of the VLAN.

fail_safe

boolean

When yes, specifies the VLAN takes the specified fail_safe_action if the system detects a loss of traffic on this VLAN’s interfaces.

Choices:

  • no

  • yes

fail_safe_action

string

Specifies the action the system takes when it does not detect any traffic on this VLAN, and the fail_safe_timeout has expired.

Choices:

  • reboot

  • restart-all

  • failover

fail_safe_timeout

integer

Specifies the number of seconds a system can run without detecting network traffic on this VLAN before it takes the fail_safe_action.

boolean

added in 1.3.0 of f5networks.f5_modules

Enables hardware syncookie mode on a VLAN.

When yes, the hardware per-VLAN SYN cookie protection is triggered when the certain traffic threshold is reached on supported platforms.

Choices:

  • no

  • yes

interfaces

list / elements=dictionary

Interfaces you want to add to the VLAN. This can include both tagged and untagged interfaces, as the tagging parameter specifies.

This parameter is mutually exclusive with the untagged_interfaces and tagged_interfaces parameters.

interface

string

The name of the interface

tagging

string

Whether the interface is tagged or untagged.

Choices:

  • tagged

  • untagged

mtu

integer

Specifies the maximum transmission unit (MTU) for traffic on this VLAN. When creating a new VLAN, if this parameter is not specified, the default value used is 1500.

This number must be between 576 to 9198.

name

string / required

The VLAN to manage. If the special VLAN ALL is specified with the state value of absent, all VLANs will be removed.

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)

sflow_poll_interval

integer

Specifies the maximum interval in seconds between two pollings.

sflow_sampling_rate

integer

Specifies the ratio of packets observed to the samples generated.

source_check

boolean

When yes, specifies the system verifies the return route to an initial packet is the same VLAN from which the packet originated.

The system performs this verification only if the auto_last_hop option is no.

Choices:

  • no

  • yes

state

string

The state of the VLAN on the system. When present, guarantees the VLAN exists with the provided attributes. When absent, removes the VLAN from the system.

Choices:

  • absent

  • present ← (default)

tag

integer

Tag number for the VLAN. The tag number can be any integer between 1 and 4094. The system automatically assigns a tag number if you do not specify a value.

tagged_interfaces

aliases: tagged_interface

list / elements=string

Specifies a list of tagged interfaces and trunks you want to configure for the VLAN. Use tagged interfaces or trunks when you want to assign a single interface or trunk to multiple VLANs.

This parameter is mutually exclusive with the untagged_interfaces and interfaces parameters.

untagged_interfaces

aliases: untagged_interface

list / elements=string

Specifies a list of untagged interfaces and trunks you want to configure for the VLAN.

This parameter is mutually exclusive with the tagged_interfaces and interfaces parameters.

Notes

Note

  • Requires BIG-IP versions >= 12.0.0

  • 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.
