mellanox.onyx.onyx_command – Run commands on remote devices running Mellanox ONYX

Note

This plugin is part of the mellanox.onyx collection (version 1.0.0).

To install it use: ansible-galaxy collection install mellanox.onyx.

To use it in a playbook, specify: mellanox.onyx.onyx_command.

Synopsis

• Sends arbitrary commands to an Mellanox ONYX network device 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 onyx_config to configure Mellanox ONYX devices.

Parameters

Parameter	Choices/Defaults	Comments
commands string / required		List of commands to send to the remote Mellanox ONYX network device. 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 string	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: any 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.
retries string	Default: 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 conditions.
wait_for 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.
