cnos_image – Perform firmware upgrade/download from a remote server on devices running Lenovo CNOS

Synopsis

  • This module allows you to work with switch firmware images. It provides a way to download a firmware image to a network device from 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 image’s location. Authentication details required by the remote server must be provided as well. By default, this method makes the newly downloaded firmware image the active image, which will be used by the switch during the next restart. 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.

Parameters

Parameter Choices/Defaults Comments
deviceType
string / required
    Choices:
  • g8272_cnos
  • g8296_cnos
  • g8332_cnos
  • NE0152T
  • 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 Ansible 2.4. The choice NE0152T is added since 2.8
enablePassword
string
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
string / required
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.
imgpath
- / required
This specifies the full file path of the image located 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.
imgtype
- / required
    Choices:
  • all
  • boot
  • os
  • onie
This specifies the firmware image type to be downloaded
outputfile
string / required
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
string / required
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
- / required
    Choices:
  • SFTP
  • SCP
  • FTP
  • TFTP
This refers to the protocol used by the network device to interact with the remote server from where to download the firmware image. 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.
serverip
- / required
This specifies the IP Address of the remote server from where the software image will be downloaded.
serverpassword
-
Specify the password for the server relating to the protocol used
serverusername
- / required
Specify the username for the server relating to the protocol used
username
string / required
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.
