short_description: Run commands on remote devices running Extreme Networks SLX-OS
|
||
|
description:
|
||
|
- Sends arbitrary commands to an SLX 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(slxos_config) to configure SLX-OS devices.
|
||
|
notes:
|
||
|
- Tested against SLX-OS 17s.1.02
|
||
|
- If a command sent to the device requires answering a prompt, it is possible
|
||
|
to pass a dict containing I(command), I(answer) and I(prompt). See examples.

description:
|
||
|
- List of commands to send to the remote SLX-OS 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.

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.

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.

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.

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.
