Examples

This chapter provides examples on how to use Netconf to manage NTP configurations on AsterNOS devices.

Modify NTP Global Configurations

Request example to modify Kdump-tools configurations via edit-config.

<config>
    <top>
        <ntp-global operation="merge">
            <vrf>default</vrf>
            <source-interface>eth0</source-interface>
        </ntp-global>
    </top>
</config>

Response example

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:0d9c9ea3-cb6b-4db2-976f-b9dda15b4be1">
  <ok/>
</rpc-reply>

Get NTP Global Configurations

Request example to retrieve NTP global configurations via get-config with subtree filter.

<filter type="subtree">
  <top>
    <ntp-global/>
  </top>
</filter>

Response example

<data>
  <top>
    <ntp-global xmlns="http://asterfusion.com/ns/yang/asternos-ntp">
      <vrf>default</vrf>
      <source-interface>eth0</source-interface>
    </ntp-global>
  </top>
</data>

Create NTP Server

NOTE

The NTP server is specified by its hostname or IP address, it can be a public NTP server address or a local NTP server, like: ‘ntp.example.com’ or ‘192.168.1.1’.

Request example to create NTP server via edit-config.

<config>
    <top>
        <ntp-servers operation="create">
            <ntp-server>
                <address>pool.ntp.org</address>
            </ntp-server>
            <ntp-server>
                <address>192.168.1.1</address>
            </ntp-server>
        </ntp-servers>
    </top>
</config>

Response example

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:df5299b4-8762-4219-8acb-57c2549a3fdf">
  <ok/>
</rpc-reply>

Delete Single NTP Server

Request example to delete single NTP server via edit-config.

<config>
    <top>
        <ntp-servers>
            <ntp-server operation="delete">
                <address>192.168.1.1</address>
            </ntp-server>
        </ntp-servers>
    </top>
</config>

Response example

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:5e1e8349-d8e4-4d20-a8e5-89fa83712aee">
  <ok/>
</rpc-reply>

Delete All NTP Servers

Request example to delete all NTP server via edit-config.

<config>
    <top>
        <ntp-servers operation="delete">
        </ntp-servers>
    </top>
</config>

Response example

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:70c89d24-6af6-4cd0-b4a8-b20f635779d3">
  <ok/>
</rpc-reply>

  <top>
    <ntp-servers/>
  </top>
</filter>

Response example

Properties Descriptions

Global configuration of ntp

Tree Diagram

module: asternos-ntp
  +--rw ntp-global
     +--rw vrf?                string
     +--rw source-interface?   string

Table of Properties

Name	Required	Type/Range	Description
ntp-global	M		Path-only node, has no configurable value. Global configuration of ntp
vrf	O	None	NTP can be enabled only in one VRF at a time. In this revision, it is either default VRF or Management VRF. Default value: default
source-interface	O	Ethernet name PortChannel name VLAN name Loopback name	This is the interface whose IP address is used as the source IP address for generating NTP traffic. User is required to make sure that the NTP server is reachable via this IP address and the same IP address is reachable from the NTP server. The source interface should be in the same VRF as the VRF NTP is enabled in.

Ntp Servers

Tree Diagram

module: asternos-ntp
  +--rw ntp-servers
     +--rw ntp-server* [address]
        +--rw address    union

Table of Properties

Name	Required	Type/Range	Description
ntp-servers	M		Path-only node, has no configurable value.
ntp-server	M		Path-only node, has no configurable value. List of address sets of the ntp server
address	O	An IPv4 address without a zone index. This type, derived from the type ipv4-address, may be used in situations where the zone is known from the context and no zone index is needed. An IPv6 address without a zone index. This type, derived from the type ipv6-address, may be used in situations where the zone is known from the context and no zone index is needed.	NTP server (IPv4, IPv6, or hostname)
