module: cnos_vlag
author: "Anil Kumar Muraleedharan (@amuraleedhar)"
short_description: Manage VLAG resources and attributes on devices running
Lenovo CNOS
description:
- This module allows you to work with virtual Link Aggregation Groups
(vLAG) related configurations. The operators used are overloaded to ensure
control over switch vLAG configurations. Apart from the regular device
connection related attributes, there are four vLAG arguments which are
overloaded variables that will perform further configurations. They are
vlagArg1, vlagArg2, vlagArg3, and vlagArg4. For more details on how to use
these arguments, see [Overloaded Variables].
This module uses SSH to manage network device configuration.
The results of the operation will be placed in a directory named 'results'
that must be created by the user in their local directory to where the
playbook is run.
