cnos_vlan - Manage VLAN resources and attributes on devices running Lenovo CNOS

New in version 2.3.

Synopsis

  • This module allows you to work with VLAN related configurations. The operators used are overloaded to ensure control over switch VLAN configurations. The first level of VLAN configuration allows to set up the VLAN range, the VLAN tag persistence, a VLAN access map and access map filter. After passing this level, there are five VLAN arguments that will perform further configurations. They are vlanArg1, vlanArg2, vlanArg3, vlanArg4, and vlanArg5. The value of vlanArg1 will determine the way following arguments will be evaluated. For more details on how to use these arguments, see [Overloaded Variables]. 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_vlan.html

Parameters

Parameter Choices/Defaults Comments
deviceType
required

(added in 2.3)
    Choices:
  • 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)
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.
username
required

(added in 2.3)
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.
vlanArg1

  • access-map
  • dot1q
  • filter
  • <1-3999> VLAN ID 1-3999 or range

  • VLAN Access Map name
  • egress-only
  • name
  • flood

  • ip
This is an overloaded vlan second argument. Usage of this argument can be found is the User Guide referenced above.
vlanArg3

  • Querier IP address
  • Querier Timeout in seconds
  • Query Interval in seconds
  • Query Max Response Time in seconds
  • Robustness Variable value
