dellemc.os9/roles/os9_ntp

NTP role

This role facilitates the configuration of network time protocol (NTP) attributes, and it specifically enables configuration of NTP server. This role is abstracted for Dell EMC PowerSwitch platforms running Dell EMC OS9.

The NTP role requires an SSH connection for connectivity to a Dell EMC OS9 device. You can use any of the built-in OS connection variables.

Role variables

• Role is abstracted using the ansible_network_os variable that can take dellemc.os9.os9 as the value.
• If os9_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

os9_ntp keys

Key	Type	Description	Support
server	list	Configures the NTP server (see server.*)	os9
server.ip	string (required)	Configures an IPv4 address for the NTP server (A.B.C.D format)	os9
server.vrf	list	Configures the NTP server for VRF instance; list item contains the names of the VRF instance	os9
server.state	string: absent,present*	Deletes the NTP server if set to absent	os9

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

Connection variables

Ansible Dell EMC network 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	os9, null*	Loads the correct terminal and cliconf plugins to communicate with the remote device

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

Example playbook

This example uses the os9_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 OS9 name.

When the os9_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 os9_ntp role. By including the role, you automatically get access to all of the tasks to configure NTP attributes.

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: dellemc.os9.os9
build_dir: ../temp/os9
  
os9_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:
     - dellemc.os9.os9_ntp

Run

ansible-playbook -i hosts leaf.yaml
