dellemc.os9.os9_command module – Run commands on remote devices running Dell OS9

Note

This module is part of the dellemc.os9 collection (version 1.0.4).

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 dellemc.os9.

To use it in a playbook, specify: dellemc.os9.os9_command.

Synopsis

  • Sends arbitrary commands to a Dell OS9 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.

  • This module does not support running commands in configuration mode. Please use M(dellemc_os9_os9_config) to configure Dell OS9 devices.

Note

This module has a corresponding action plugin.

Parameters

Parameter

Comments

commands

list / elements=string / required

List of commands to send to the remote os9 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 retries has expired.

interval

integer

Configures the interval in seconds to wait between retries of the command. If the command does not pass the specified conditions, the interval indicates how long to wait before trying the command again.

Default: 1

match

string

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.

Choices:

  • all ← (default)

  • any

provider

dictionary

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:

  • no

  • yes

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

Password to authenticate the SSH session to the remote device. 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.

ssh_keyfile

path

Path to an ssh key used to authenticate the SSH session to the remote device. 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 idle timeout (in seconds) for the connection. Useful if the console freezes before continuing. For example when saving configurations.

username

string

User to authenticate the SSH session to the remote device. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_USERNAME will be used instead.

retries

integer

Specifies the number of retries a command should be tried before it is considered failed. The command is run on the target device every retry and evaluated against the wait_for conditions.

Default: 10

wait_for

list / elements=string

List of conditions to evaluate against the output of the command. The task will wait for each condition to be true before moving forward. If the conditional is not true within the configured number of retries, the task fails. See examples.

Notes

Note

  • This module requires Dell OS9 version 9.10.0.1P13 or above.

  • This module requires to increase the ssh connection rate limit. Use the following command ip ssh connection-rate-limit 60 to configure the same. This can be done via M(os9_config) module as well.

Examples

tasks:
  - name: run show version on remote devices
    os9_command:
      commands: show version
  - name: run show version and check to see if output contains OS9
    os9_command:
      commands: show version
      wait_for: result[0] contains OS9
  - name: run multiple commands on remote nodes
    os9_command:
      commands:
        - show version
        - show interfaces
  - name: run multiple commands and evaluate the output
    os9_command:
      commands:
        - show version
        - show interfaces
      wait_for:
        - result[0] contains OS9
