required
    Choices:
  • running-config
  • startup-config
Default:
None
This refers to the type of configuration which will be used for the rolling back process. 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
required

(added in 2.3)
    Choices:
  • g8272_cnos
  • g8296_cnos
  • g8332_cnos
  • NE1072T
  • NE1032
  • NE1032T
  • NE10032
  • NE2572

enablePassword
(added in 2.3)
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
required

(added in 2.3)
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
required

(added in 2.3)
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
required

(added in 2.3)
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
Default:
None
This refers to the protocol used by the network device to interact with the remote server from where to download 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
required
Default:
None
This specifies the full file path of the configuration file 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.

None
This specifies the IP Address of the remote server from where the backup configuration will be downloaded.
serverpassword
required
Default:
None
Specify password for the server relating to the protocol used.
