module: ios_facts
version_added: "2.2"
author: "Peter Sprygada (@privateip)"
short_description: Collect facts from remote devices running IOS
description:
- Collects a base set of device facts from a remote device that
is running IOS. 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.
extends_documentation_fragment: ios
options:
gather_subset:
description:
- When supplied, this argument will restrict the facts collected
to a given subset. Possible values for this argument include
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.
required: false
default: '!config'
