## Synopsis

- This module manages properties of Link Aggregation Group 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 |  | A list of link aggregation group configurations.
| link_protection boolean | Choices: no yes | This boolean option indicates if link protection should be enabled for the LAG interface. If value is `True` link protection is enabled on LAG and if value is `False` link protection is disabled.
| members list |  | List of member interfaces of the link aggregation group. The value can be single interface or list of interfaces.
|  | link_type - | Choices: primary backup | The value of this options configures the member link as either `primary` or `backup`. Value `primary` configures primary interface for link-protection mode and `backup` configures backup interface for link-protection mode.
|  | member string |  | Name of the member interface.
| mode - | Choices: active passive | LAG mode. A value of `passive` will enable LACP in `passive` mode that is it will respond to LACP packets and `active` configures the link to initiate transmission of LACP packets.
| name string / required |  | Name of the link aggregation group (LAG).
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.
