New in version 2.1.
Sends an arbitrary command to an NXOS node and returns the results read from the device. This module includes an argument that will cause the module to wait for a specific condition before returning or timing out if the condition is not met.
parameter | required | default | choices | comments |
---|---|---|---|---|
commands | yes |
The commands to send to the remote NXOS device over the configured provider. The resulting output from the command is returned. If the wait_for argument is provided, the module is not returned until the condition is satisfied or the number of retires as expired.
The commands argument also accepts an alternative form that allows for complex values that specify the command to run and the output format to return. This can be done on a command by command basis. The complex argument supports the keywords
command and output where command is the command to run and output is one of 'text' or 'json'. |
||
host | yes | 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. |
||
interval | no | 1 | Configures the interval in seconds to wait between retries of the command. If the command does not pass the specified conditional, the interval indicates how to long to wait before trying the command again. |
|
match (added in 2.2)
| no | all | The match argument is used in conjunction with the wait_for argument to specify the match policy. Valid values are all or any . If the value is set to all then all conditionals in the wait_for must be satisfied. If the value is set to any then only one of the values must be satisfied. |
|
password | no | 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 | no | 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). |
|
provider | no | Convenience method that allows all nxos arguments to be passed as a dict object. All constraints (required, choices, etc) must be met either by individual arguments or values in this dict. |
||
retries | no | 10 | Specifies the number of retries a command should by tried before it is considered failed. The command is run on the target device every retry and evaluated against the wait_for conditionals. |
|
ssh_keyfile | no | 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. |
||
transport | yes | 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. |
|
use_ssl | no |
| Configures the transport to use SSL if set to true only when the transport=nxapi , otherwise this value is ignored. |
|
username | no | Configures the username to use to authenticate the connection to the remote device. The value of username 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. |
||
wait_for (added in 2.2)
| no |
Specifies what to evaluate from the output of the command and what conditionals to apply. This argument will cause the task to wait for a particular conditional to be true before moving forward. If the conditional is not true by the configured retries, the task fails. See examples. aliases: waitfor

# Note: examples below use the following provider dict to handle # transport and authentication to the node. vars: cli: host: "{{ inventory_hostname }}" username: admin password: admin transport: cli - name: run show version on remote devices nxos_command: commands: show version provider: "{{ cli }}" - name: run show version and check to see if output contains Cisco nxos_command: commands: show version wait_for: result[0] contains Cisco provider: "{{ cli }}" - name: run multiple commands on remote nodes nxos_command: commands: - show version - show interfaces provider: "{{ cli }}" - name: run multiple commands and evaluate the output nxos_command: commands: - show version - show interfaces wait_for: - result[0] contains Cisco - result[1] contains loopback0 provider: "{{ cli }}" - name: run commands and specify the output format nxos_command: commands: - command: show version output: json provider: "{{ cli }}"
Common return values are documented here Common Return Values, the following are the fields unique to this module:
name | description | returned | type | sample |
---|---|---|---|---|
stdout_lines | The value of stdout split into a list | always | list | [['...', '...'], ['...'], ['...']] |
stdout | the set of responses from the commands | always | list | ['...', '...'] |
failed_conditions | the conditionals that failed | failed | list | ['...', '...'] |
