New in version 2.6.
cnos_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.Parameter | Choices/Defaults | Comments | |
---|---|---|---|
commands
required (added in 2.6) |
List of commands to send to the remote 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 retires as expired.
|
||
interval
(added in 2.6) |
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
(added in 2.6) |
|
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. |
|
provider
(added in 2.6) |
A dict object containing connection details.
|
||
username |
Configures the username to use to authenticate the connection to the remote device. This value is used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable
ANSIBLE_NET_USERNAME will be used instead. |
||
host
required |
Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport.
|
||
ssh_keyfile |
Specifies the SSH key to use to authenticate the connection to the remote device. This value is the path to the key used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable
ANSIBLE_NET_SSH_KEYFILE will be used instead. |
||
timeout |
Default: 10
|
Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.
|
|
password |
Specifies the password to use to authenticate the connection to the remote device. This value is used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable
ANSIBLE_NET_PASSWORD will be used instead. |
||
port |
Default: 22
|
Specifies the port to use when building the connection to the remote device.
|
|
retries
(added in 2.6) |
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
(added in 2.6) |
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.
|
# Note: examples below use the following provider dict to handle
# transport and authentication to the node.

register: result
- assert:
that:
- "result.changed == false"
- "result.stdout is defined"
- name: get output for single command
cnos_command:
commands: ['show version']
provider: "{{ cli }}"
register: result
- assert:

Common return values are documented here, the following are the fields unique to this module:
Key | Returned | Description |
---|---|---|
failed_conditions
list
|
failed |
the conditionals that failed
Sample:
['...', '...']
|
stdout
list
|
always |
the set of responses from the commands
Sample:
['...', '...']
|
stdout_lines
list
|
always |
The value of stdout split into a list
Sample:
[['...', '...'], ['...'], ['...']]
