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

Note

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

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 dellemc_os9_os9_config to configure Dell OS9 devices.

Note

This module has a corresponding action plugin.

Parameters

Parameter		Choices/Defaults	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		Default: 1	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.
match string		Choices: all ← any	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.
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	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		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		Default: 10	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.
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.
