- Collects a base set of device facts from a remote device that
|
|
is running SLX-OS. This module prepends all of the

|
base network fact keys with C(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.

all, hardware, config, and interfaces. Can specify a list of

values to include a larger subset. Values can also be used

with an initial C(M(!)) to specify that a specific subset should

not be collected.
