NTP Role

This role helps set up Network Time Protocol (NTP) features for Dell networking devices. It supports Dell operating systems: dellos6, dellos9, and dellos10. It allows you to configure the NTP server and other NTP settings specifically for dellos10.

To use this role, you need an SSH connection to a Dell EMC Networking device. You can utilize any of the built-in connection variables offered by the operating system.

Installation

You can install this role using the following command:

ansible-galaxy install Dell-Networking.dellos-ntp

Role Variables

Here's a summary of the variables you can use in this role:

• The role uses the variable ansible_network_os, which can take values dellos6, dellos9, or dellos10.
• If dellos_cfg_generate is true, configuration commands are generated in a file.
• Any variable set to "absent" will not be configured; similarly, setting any variable to empty will also prevent it from being set.
• Remember that variable names and values are case-sensitive.

Connection Variables

To connect to Dell EMC devices, you need to provide connection details. These can be kept in the group_vars or host_vars directories, in your inventory, or in the playbook itself.

NOTE: An asterisk (*) indicates the default value if none is specified.

Dependencies

The dellos-ntp role relies on core Ansible modules, which were added in Ansible version 2.2.0.

Example Playbook

Here's a simple example that uses the dellos-ntp role to configure the NTP server, source IP, authentication, and broadcast service. You will first create a hosts file with switch details and appropriate variables.

Sample hosts file

leaf1 ansible_host=<ip_address>

Sample host_vars/leaf1

host: leaf1
ansible_ssh_user: xxxxx
ansible_ssh_pass: xxxxx
ansible_network_os: dellos10
build_dir: ../temp/dellos10

dellos_ntp:
  source: ethernet 1/1/2
  master: 5
  authenticate: true
  authentication_key:
    - key_num: 123
      key_string_type: 7
      key_string: test
      state: present
  trusted_key:
    - key_num: 1323
      state: present
  server:
    - ip: 2.2.2.2
      key: 345
      prefer: true
      state: present
  intf:
    ethernet 1/1/2:
      disable: true
      broadcast: true
