exos_command – Run commands on remote devices running Extreme EXOS

New in version 2.6.

Synopsis

  • Sends arbitrary commands to an Extreme EXOS 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 configuration commands. Please use exos_config to configure EXOS devices.

Parameters

Parameter Choices/Defaults Comments
commands
- / required
List of commands to send to the remote EXOS 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
-
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
-
    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
-
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
-
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

  • If a command sent to the device requires answering a prompt, it is possible to pass a dict containing command, answer and prompt. See examples.
