|
||||
Sends arbitrary commands to an mlnxos 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(mlnxos_config) to configure Mellanox MLNX-OS devices.

- tested on Mellanox OS 3.6.4000

|

List of commands to send to the remote mlnxos 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.

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.

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.
