dellos-vlt
VLT role
This role facilitates the configuration of the basics of virtual link trunking (VLT) to provide a loop-free topology. This role is abstracted for Dell EMC Networking dellos9 and dellos10.
The VLT role requires an SSH connection for connectivity to your Dell EMC Networking device. You can use any of the built-in OS connection variables .
Installation
ansible-galaxy install Dell-Networking.dellos-vlt
Role variables
- Role is abstracted using the ansible_network_os variable that can take dellos9 and dellso10 values
- If dellos_cfg_generate is set to true, the variable generates the role configuration commands in a file
- Any role variable with a corresponding state variable set to absent negates the configuration of that variable
- Setting an empty value for any variable negates the corresponding configuration
- Variables and values are case-sensitive

Connection variables
Ansible Dell EMC Networking OS roles require connection information to establish communication with the nodes in your inventory. This information can exist in the Ansible group_vars or host_vars directories or inventory, or in the playbook itself.
Key | Required | Choices | Description |
---|---|---|---|
ansible_host |
yes | Specifies the hostname or address for connecting to the remote device over the specified transport | |
ansible_port |
no | Specifies the port used to build the connection to the remote device; if value is unspecified, the ANSIBLE_REMOTE_PORT option is used; it defaults to 22 | |
ansible_ssh_user |
no | Specifies the username that authenticates the CLI login for the connection to the remote device; if value is unspecified, the ANSIBLE_REMOTE_USER environment variable value is used | |
ansible_ssh_pass |
no | Specifies the password that authenticates the connection to the remote device | |
ansible_become |
no | yes, no* | Instructs the module to enter privileged mode on the remote device before sending any commands; if value is unspecified, the ANSIBLE_BECOME environment variable value is used, and the device attempts to execute all commands in non-privileged mode |
ansible_become_method |
no | enable, sudo* | Instructs the module to allow the become method to be specified for handling privilege escalation; if value is unspecified, the ANSIBLE_BECOME_METHOD environment variable value is used. |
ansible_become_pass |
no | Specifies the password to use if required to enter privileged mode on the remote device; if ansible_become is set to no this key is not applicable. |
|
ansible_network_os |
yes | dellos6/dellos9/dellos10, null* | Loads the correct terminal and cliconf plugins to communicate with the remote device |
NOTE: Asterisk (*) denotes the default value if none is specified.
Dependencies
The dellos-vlt role is built on modules included in the core Ansible code. These modules were added in ansible version 2.2.0.
Example playbook
This example uses the dellos-vlt role to setup a VLT-domain. It creates a hosts file with the switch details and corresponding variables.The hosts file should define the ansible_network_os variable with corresponding Dell EMC networking OS name.
When dellos_cfg_generate is set to true, the variable generates the configuration commands as a .part file in build_dir path. By default, the variable is set to false. It writes a simple playbook that only references the dellos-vlt role.
