nxos_facts - Gets facts about NX-OS switches

New in version 2.1.

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_subset
(added in 2.2)
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
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.
username
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.
authorize
bool

(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.
ssh_keyfile
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.
use_proxy
bool

(added in 2.5)
    Choices:
  • no
  • yes ←
If no, the environment variables http_proxy and https_proxy will be ignored.
auth_pass
(added in 2.5.3)
Default:
none
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.
host
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.
timeout
(added in 2.3)
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).
use_ssl
bool
    Choices:
  • no ←
  • yes
Configures the transport to use SSL if set to true only when the transport=nxapi, otherwise this value is ignored.
password
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.
validate_certs
bool
    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.
port 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).
transport
required
Default:
cli
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.

Notes

Note

  • This module is only supported on the NX-OS device that supports JSON structured output. NX-OS OS version should be 6.0(2)A8 or 7.x or later.
  • For information on using CLI and NX-API see the NXOS Platform Options guide
  • For more information on using Ansible to manage network devices see the Ansible Network Guide
  • For more information on using Ansible to manage Cisco devices see the Cisco integration page.

Examples

- nxos_facts:

- nxos_facts:
    gather_subset:
      - config

# Do not collect hardware facts
- nxos_facts:
    gather_subset:
      - "!hardware"
