cnos_command - Execute a single command on devices running Lenovo CNOS

New in version 2.3.

Synopsis

  • This module allows you to modify the switch running configuration. It provides a way to execute a single CNOS command on a switch by evaluating the current running configuration and executing the command only if the specific setting has not been already configured. The CNOS command is passed as an argument of the method. This module uses SSH to manage network device configuration. The results of the operation will be placed in a directory named ‘results’ that must be created by the user in their local directory to where the playbook is run. For more information about this module from Lenovo and customizing it usage for your use cases, please visit http://systemx.lenovofiles.com/help/index.jsp?topic=%2Fcom.lenovo.switchmgt.ansible.doc%2Fcnos_command.html

Options

parameter required default choices comments
clicommand
yes
This specifies the CLI command as an attribute to this method. The command is passed using double quotes. The variables can be placed directly on to the CLI commands or can be invoked from the vars directory.
deviceType
(added in 2.3)
yes
  • g8272_cnos
  • g8296_cnos
  • g8332_cnos
  • NE1072T
  • NE1032
  • NE1032T
  • NE10032
  • NE2572
This specifies the type of device where the method is executed. The choices NE1072T,NE1032,NE1032T,NE10032, NE2572 are added since version 2.4
enablePassword
(added in 2.3)
no
Configures the password used to enter Global Configuration command mode on the switch. If the switch does not request this password, the parameter is ignored.While generally the value should come from the inventory file, you can also specify it as a variable. This parameter is optional. If it is not specified, no default value will be used.
host
(added in 2.3)
yes
This is the variable used to search the hosts file at /etc/ansible/hosts and identify the IP address of the device on which the template is going to be applied. Usually the Ansible keyword {{ inventory_hostname }} is specified in the playbook as an abstraction of the group of network elements that need to be configured.
outputfile
(added in 2.3)
yes
This specifies the file path where the output of each command execution is saved. Each command that is specified in the merged template file and each response from the device are saved here. Usually the location is the results folder, but you can choose another location based on your write permission.
password
(added in 2.3)
yes
Configures the password used to authenticate the connection to the remote device. The value of the password parameter is used to authenticate the SSH session. While generally the value should come from the inventory file, you can also specify it as a variable. This parameter is optional. If it is not specified, no default value will be used.
username
(added in 2.3)
yes
Configures the username used to authenticate the connection to the remote device. The value of the username parameter is used to authenticate the SSH session. While generally the value should come from the inventory file, you can also specify it as a variable. This parameter is optional. If it is not specified, no default value will be used.
