module: asa_command
version_added: "2.2"
author: "Peter Sprygada (@privateip) & Patrick Ogenstad (@ogenstad)"
short_description: Run arbitrary commands on Cisco ASA devices.
description:
- Sends arbitrary commands to an ASA node and returns the results
read from the device. The M(asa_command) 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.
extends_documentation_fragment: asa
options:
commands:
description:
- List of commands to send to the remote ios device over the
configured provider. The resulting output from the command
is returned. If the I(waitfor) argument is provided, the
module is not returned until the condition is satisfied or
the number of retires as expired.
required: true
waitfor:
description:
- List of conditions to evaluate against the output of the
command. The task will wait for a 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.
required: false
default: null
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
waitfor conditions.
required: false
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.
required: false
default: 1
