cnos_backup - Backup the current running or startup configuration to a remote server on devices running Lenovo CNOS

New in version 2.3.

Synopsis

  • This module allows you to work with switch configurations. It provides a way to back up the running or startup configurations of a switch to a remote server. This is achieved by periodically saving a copy of the startup or running configuration of the network device to a remote server using FTP, SFTP, TFTP, or SCP. The first step is to create a directory from where the remote server can be reached. The next step is to provide the full file path of the location where the configuration will be backed up. Authentication details required by the remote server must be provided as well. 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.

Options

parameter required default choices comments
configType
yes
  • running-config
  • startup-config
This specifies what type of configuration will be backed up. The choices are the running or startup configurations. There is no default value, so it will result in an error if the input is incorrect.
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.
protocol
yes
  • SFTP
  • SCP
  • FTP
  • TFTP
This refers to the protocol used by the network device to interact with the remote server to where to upload the backup configuration. The choices are FTP, SFTP, TFTP, or SCP. Any other protocols will result in error. If this parameter is not specified, there is no default value to be used.
rcpath
yes
This specifies the full file path where the configuration file will be copied on the remote server. In case the relative path is used as the variable value, the root folder for the user of the server needs to be specified.
rcserverip
yes
-This specifies the IP Address of the remote server to where the configuration will be backed up.
serverpassword
yes
Specify the password for the server relating to the protocol used.
serverusername
yes
Specify the username for the server relating to the protocol 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.
