## Synopsis

- Collects facts from Cisco Nexus devices running the NX-OS operating system. Fact collection is supported over both Cli and Nxapi transports. This module prepends all of the base network fact keys with `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.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
gather_network_resources - added in 2.9 |  | When supplied, this argument will restrict the facts collected to a given subset. Possible values for this argument include all and the resources like interfaces, vlans etc. Can specify a list of values to include a larger subset. Values can also be used with an initial `!` to specify that a specific subset should not be collected. Valid subsets are 'all', 'bfd_interfaces', 'lag_interfaces', 'telemetry', 'vlans', 'lacp', 'lacp_interfaces', 'interfaces', 'l3_interfaces', 'l2_interfaces', 'lldp_global'.
gather_subset - | Default: "!config" | When supplied, this argument will restrict the facts collected to a given subset. Possible values for this argument include all, hardware, config, legacy, and interfaces. Can specify a list of values to include a larger subset. Values can also be used with an initial `!` to specify that a specific subset should not be collected.
provider dictionary |  | Deprecated Starting with Ansible 2.5 we recommend using `connection: network_cli`. This option is only required if you are using NX-API. For more information please see the NXOS Platform Options guide. A dict object containing connection details.
| auth_pass string added in 2.5.3 |  | Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_AUTH_PASS` will be used instead.
| authorize boolean added in 2.5.3 | Choices: no ← yes | Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_AUTHORIZE` will be used instead.
| host string / required |  | Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport.
| password string |  | Specifies the password to use to authenticate the connection to the remote device. This is a common argument used for either cli or nxapi transports. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_PASSWORD` will be used instead.
| port integer | Default: "0 (use common port)" | Specifies the port to use when building the connection to the remote device. This value applies to either cli or nxapi. The port value will default to the appropriate transport common port if none is provided in the task. (cli=22, http=80, https=443).
| ssh_keyfile string |  | Specifies the SSH key to use to authenticate the connection to the remote device. This argument is only used for the cli transport. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_SSH_KEYFILE` will be used instead.
| timeout integer | Default: 10 | Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error. NX-API can be slow to return on long-running commands (sh mac, sh bgp, etc).
| transport string / required | Choices: cli ← nxapi | Configures the transport connection to use when connecting to the remote device. The transport argument supports connectivity to the device over cli (ssh) or nxapi.
| use_proxy boolean added in 2.5 | Choices: no yes ← | If `no`, the environment variables `http_proxy` and `https_proxy` will be ignored.
| use_ssl boolean | Choices: no ← yes | Configures the transport to use SSL if set to `yes` only when the `transport=nxapi`, otherwise this value is ignored.
| username string |  | Configures the username to use to authenticate the connection to the remote device. This value is used to authenticate either the CLI login or the nxapi authentication depending on which transport is used. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_USERNAME` will be used instead.
| validate_certs boolean | Choices: no yes ← | If `no`, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. If the transport argument is not nxapi, this value is ignored.
