cnos_vlag – Manage VLAG resources and attributes on devices running Lenovo CNOS

Synopsis

• This module allows you to work with virtual Link Aggregation Groups (vLAG) related configurations. The operators used are overloaded to ensure control over switch vLAG configurations. Apart from the regular device connection related attributes, there are four vLAG arguments which are overloaded variables that will perform further configurations. They are vlagArg1, vlagArg2, vlagArg3, and vlagArg4. 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.

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.
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.
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.
vlagArg1 - / required	Choices: enable auto-recovery config-consistency isl mac-address-table peer-gateway priority startup-delay tier-id vrrp instance hlthchk	This is an overloaded vlag first argument. Usage of this argument can be found is the User Guide referenced above.
vlagArg2 -	Choices: Interval in seconds disable or strict Port Aggregation Number VLAG priority Delay time in seconds VLAG tier-id value VLAG instance number keepalive-attempts keepalive-interval retry-interval peer-ip	This is an overloaded vlag second argument. Usage of this argument can be found is the User Guide referenced above.
vlagArg3 -	Choices: enable or port-aggregation Number of keepalive attempts Interval in seconds Interval in seconds VLAG health check peer IP4 address	This is an overloaded vlag third argument. Usage of this argument can be found is the User Guide referenced above.
vlagArg4 -	Choices: Port Aggregation Number default or management	This is an overloaded vlag fourth argument. Usage of this argument can be found is the User Guide referenced above.
