Synopsis

  • Manage VLANs on a BIG-IP system

Parameters

Parameter Choices/Defaults Comments
cmp_hash
string
    Choices:
  • default
  • destination-address
  • source-address
  • dst-ip
  • src-ip
  • dest
  • destination
  • source
  • dst
  • src
Specifies how the traffic on the VLAN will be disaggregated. The value selected 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 that the default CMP hash uses L4 ports.
When creating a new VLAN, if this parameter is not specified, the default of default is used.
dag_round_robin
boolean
    Choices:
  • no
  • yes
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 of (no) is used.
dag_tunnel
string
    Choices:
  • inner
  • outer
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 of outer is used.
This parameter is not supported on Virtual Editions of BIG-IP.
description
string
The description to give to the VLAN.
fail_safe
boolean
    Choices:
  • no
  • yes
When yes, specifies that the VLAN takes the specified fail_safe_action if the system detects a loss of traffic on this VLAN's interfaces.
fail_safe_action
string
    Choices:
  • reboot
  • restart-all
  • failover
Specifies the action that the system takes when it does not detect any traffic on this VLAN, and the fail_safe_timeout has expired.
fail_safe_timeout
integer
Specifies the number of seconds that a system can run without detecting network traffic on this VLAN before it takes the fail_safe_action.
hw_syn_cookie
boolean
added in 1.3.0 of f5networks.f5_modules
    Choices:
  • no
  • yes
Enables hardware syncookie mode on a VLAN.
When yes, the hardware per-VLAN SYN cookie protection will be triggered when the certain traffic threshold is reached on supported platforms.
interfaces
list / elements=dictionary
Interfaces that you want added 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
    Choices:
  • tagged
  • untagged
Whether the interface is tagged or 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 will be 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 then all VLANs will be removed.
partition
string
Default:
"Common"
Device partition to manage resources on.
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.
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.
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
    Choices:
  • 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
    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.
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
    Choices:
  • no
  • yes
When yes, specifies that the system verifies that 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.
state
string
    Choices:
  • absent
  • present ←
The state of the VLAN on the system. When present, guarantees that the VLAN exists with the provided attributes. When absent, removes the VLAN from the system.
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
list / elements=string
Specifies a list of tagged interfaces and trunks that 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.

aliases: tagged_interface
untagged_interfaces
list / elements=string
Specifies a list of untagged interfaces and trunks that you want to configure for the VLAN.
This parameter is mutually exclusive with the tagged_interfaces and interfaces parameters.

aliases: untagged_interface

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.
