## Synopsis

- This module manages the interfaces on Juniper Junos OS network 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 |  | The provided configuration
| description string |  | Interface description.

duplex
string

Choices:
- automatic
- full-duplex
- half-duplex

Interface link status. Applicable for Ethernet interfaces only, either in half duplex, full duplex or in automatic state which negotiates the duplex automatically.

enabled
boolean

Choices:
- no
- yes ←

Administrative state of the interface.
Set the value to `true` to administratively enabled the interface or `false` to disable it.

| hold_time dictionary |  | The hold time for given interface name.
|  | down integer |  | The link down hold time in milliseconds.
|  | up integer |  | The link up hold time in milliseconds.
| mtu integer |  | MTU for a specific interface. Applicable for Ethernet interfaces only.
| name string / required |  | Full name of interface, e.g. ge-0/0/0.
| speed integer |  | Interface link speed. Applicable for Ethernet interfaces only.

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.

## Return Values

Common return values are documented here, the following are the fields unique to this module:

Key | Returned | Description
--- | --- | ---
after list | when changed | The configuration as structured data after module completion. Sample: The configuration returned will always be in the same format of the parameters above.
before list | always | The configuration as structured data prior to module invocation. Sample: The configuration returned will always be in the same format of the parameters above.
xml list | always | The set of xml rpc payload pushed to the remote device. Sample: ['xml 1', 'xml 2', 'xml 3']

## Status
