dellos9_command – Run commands on remote devices running Dell OS9

Synopsis

  • Sends arbitrary commands to a Dell OS9 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 dellos9_config to configure Dell OS9 devices.

Parameters

Parameter Choices/Defaults Comments
commands
list / required
List of commands to send to the remote dellos9 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 retries has expired.
interval
integer
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
string
added in 2.5
    Choices:
  • all ←
  • any
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
dictionary
A dict object containing connection details.
host
string / 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.
password
string
Password to authenticate the SSH session to the remote device. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_PASSWORD will be used instead.
port
integer
Default:
22
Specifies the port to use when building the connection to the remote device.
ssh_keyfile
path
Path to an ssh key used to authenticate the SSH session to the remote device. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_SSH_KEYFILE will be used instead.
timeout
integer
Default:
10
Specifies idle timeout (in seconds) for the connection. Useful if the console freezes before continuing. For example when saving configurations.
username
string
User to authenticate the SSH session to the remote device. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_USERNAME will be used instead.
retries
integer
Default:
10
Specifies the number of retries a command should be 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
list
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.

Notes

Note

  • This module requires Dell OS9 version 9.10.0.1P13 or above.

  • This module requires to increase the ssh connection rate limit. Use the following command ip ssh connection-rate-limit 60 to configure the same. This can be done via dellos9_config module as well.
