description:
|
|
- Collects a base set of device facts from a remote device that
|
|
is running VyOS. The M(vyos_facts) module prepends all of the
|
|
base network fact keys with U(ansible_net_<fact>). The facts
|
|
module will always collect a base set of facts from the device
|
|
and can enable or disable collection of additional facts.

- When supplied, this argument will restrict the facts collected

to a given subset. Possible values for this argument inlcude

|
all, hardware, config, and interfaces. Can specify a list of
|
|
values to include a larger subset. Values can also be used
|
|
with an initial M(!) to specify that a specific subset should
|
|
not be collected.
