cisco.nxos.nxos_facts module – Gets facts about NX-OS switches

Note

This module is part of the cisco.nxos collection (version 3.2.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install cisco.nxos.

To use it in a playbook, specify: cisco.nxos.nxos_facts.

New in cisco.nxos 1.0.0

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.

Note

This module has a corresponding action plugin.

Parameters

Parameter

Comments

available_network_resources

boolean

When ‘True’ a list of network resources for which resource modules are available will be provided.

Choices:

  • false ← (default)

  • true

gather_network_resources

list / elements=string

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, acls, acl_interfaces, ospfv2, ospfv3, ospf_interfaces, bgp_global, bgp_address_family, route_maps, prefix_lists, logging_global, ntp_global, snmp_server.

gather_subset

list / elements=string

When supplied, this argument will restrict the facts collected to a given subset. Possible values for this argument include all, hardware, config, legacy, interfaces, and min. 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.

Default: ["min"]

provider

dictionary

Deprecated

Starting with Ansible 2.5 we recommend using connection: network_cli.

Starting with Ansible 2.6 we recommend using connection: httpapi for NX-API.

This option will be removed in a release after 2022-06-01.

For more information please see the https://docs.ansible.com/ansible/latest/network/user_guide/platform_nxos.html.

A dict object containing connection details.

auth_pass

string

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

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.

Choices:

  • false ← (default)

  • true

host

string

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

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

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

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.

Choices:

  • "cli" ← (default)

  • "nxapi"

use_proxy

boolean

If no, the environment variables http_proxy and https_proxy will be ignored.

Choices:

  • false

  • true ← (default)

use_ssl

boolean

Configures the transport to use SSL if set to yes only when the transport=nxapi, otherwise this value is ignored.

Choices:

  • false ← (default)

  • true

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

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.

Choices:

  • false ← (default)

  • true
