NTP role

This role facilitates the configuration of network time protocol (NTP) attributes. This role is abstracted for dellos6, dellos9, and dellos10. It specifically enables configuration of NTP server for all three dellos and NTP source, authentication and broadcast service in dellos10.

The NTP 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-ntp

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_ntp 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-ntp 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-ntp role to set the NTP server, source ip, authentication and broadcast service. 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 the dellos_cfg_generate variable is set to true, it generates the configuration commands as a .part file in build_dir path. By default it is set to false. The example writes a simple playbook that only references the dellos-ntp role.

By including the role, you automatically get access to all of the tasks to configure NTP attributes. The sample host_vars is for dellos10.

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

Simple playbook to setup NTP - leaf.yaml

- hosts: leaf1
  roles:
     - Dell-Networking.dellos-ntp

Run

ansible-playbook -i hosts leaf.yaml
