## 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.

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']
