module: aireos_command
version_added: "2.4"
author: "James Mighion (@jmighion)"
short_description: Run commands on remote devices running Cisco WLC
description:
- Sends arbitrary commands to an aireos 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(aireos_config) to configure WLC devices.
extends_documentation_fragment: aireos
options:
commands:
description:
- List of commands to send to the remote aireos device over the
configured provider. The resulting output from the command
is returned. If the I(wait_for) argument is provided, the
module is not returned until the condition is satisfied or
the number of retries has expired.
required: true
wait_for:
description:
- 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.
aliases: ['waitfor']
match:
description:
- The I(match) argument is used in conjunction with the
I(wait_for) argument to specify the match policy. Valid
values are C(all) or C(any). If the value is set to C(all)
then all conditionals in the wait_for must be satisfied. If
the value is set to C(any) then only one of the values must be
satisfied.
default: all
choices: ['any', 'all']
retries:
description:
- 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
I(wait_for) conditions.
default: 10
interval:
description:
- 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
