System role

This role facilitates the configuration of global system attributes, and is abstracted for dellos6, dellos9, and dellos10. It specifically enables configuration of hostname and enable password for all three dellos. In addition, dellos9 supports the configuration of management route, hash alogrithm, clock, line terminal, banner, and reload type.

The dellos-system role requires an SSH connection for connectivity to a Dell EMC Networking device. You can use any of the built-in OS connection variables .

Installation

ansible-galaxy install Dell-Networking.dellos-system

Role variables

• Role is abstracted using the ansible_network_os variable that can take dellos9, dellos6, and dellos10 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

dellos_system keys

NOTE: Asterisk (*) denotes the default value if none is specified.

Connection variables

Ansible Dell EMC Networking 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.

NOTE: Asterisk (*) denotes the default value if none is specified.

Dependencies

The dellos-system 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-system role to completely set the NTP server, hostname, enable password, management route, hash alogrithm, clock, line terminal, banner and reload type. 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. The system role writes a simple playbook that only references the dellos-system role. By including the role, you automatically get access to all of the tasks to configure system features.
