## Synopsis

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

## Requirements

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

- ncclient (>=v0.6.4)

## Parameters

Parameter | Choices/Defaults | 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 | Choices: no yes | 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
| 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 |  | 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.
state string | Choices: merged ← replaced overridden deleted | The state of the configuration after module completion

## 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.
