junipernetworks.junos.junos_l2_interfaces module – L2 interfaces resource module

Note

This module is part of the junipernetworks.junos collection (version 4.0.0).

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 junipernetworks.junos. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: junipernetworks.junos.junos_l2_interfaces.

New in junipernetworks.junos 1.0.0

Synopsis

  • This module provides declarative management of a Layer-2 interface on Juniper JUNOS devices.

Note

This module has a corresponding action plugin.

Requirements

The below requirements are needed on the host that executes this module.

  • ncclient (>=v0.6.4)

Parameters

Parameter

Comments

config

list / elements=dictionary

A dictionary of Layer-2 interface options

access

dictionary

Configure the interface as a Layer 2 access mode.

vlan

string

Configure the access VLAN ID.

enhanced_layer

boolean

True if your device has Enhanced Layer 2 Software (ELS). If the l2 configuration is under interface-mode the value is True else if the l2 configuration is under port-mode value is False

Choices:

  • false

  • true

name

string / required

Full name of interface, e.g. ge-0/0/1.

trunk

dictionary

Configure the interface as a Layer 2 trunk mode.

allowed_vlans

list / elements=string

List of VLANs to be configured in trunk port. It’s used as the VLAN range to ADD or REMOVE from the trunk.

native_vlan

string

Native VLAN to be configured in trunk port. It is used as the trunk native VLAN ID.

unit

integer

Logical interface number. Value of unit should be of type integer.

running_config

string

This option is used only with state parsed.

The value of this option should be the output received from the Junos device by executing the command show interfaces.

The state parsed reads the configuration from running_config option and transforms it into Ansible structured data as per the resource module’s argspec and the value is then returned in the parsed key within the result.

state

string

The state of the configuration after module completion

Choices:

  • "merged" ← (default)

  • "replaced"

  • "overridden"

  • "deleted"

  • "gathered"

  • "parsed"

  • "rendered"

Notes

Note

  • This module requires the netconf system service be enabled on the remote device being managed.

  • Tested against vSRX JUNOS version 18.4R1.

  • This module works with connection netconf. See the Junos OS Platform Options.
