Today, I will talk to you about the case analysis of NTP configuration, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

First, the network device is configured as a NTP server.

1. Configure the NTP master clock

Ntp-service refclock-master 2

two。 Turn on NTP authentication

Ntp-service authentication enable

3. Configure the NTP clock source local interface, which may not be configured.

Ntp-service source-interface loopback0

4. Configure NTP server service authentication password

Ntp-service authentication-keyid 1 authentication-mode md5 cipher admin

5. Configure the trusted key number

Ntp-service reliable authentication-keyid 1

6. Enable NTP server function

Undo ntp-service disable

Second, the network device is configured as a NTP client.

1. Turn on NTP authentication

Ntp-service authentication enable

2. Configure NTP service authentication password

Ntp-service authentication-keyid 1 authentication-mode md5 cipher admin

3. Configure the key number

Ntp-service reliable authentication-keyid 1

4. Configure the NTP server address

Ntp-service unicast-server 192.168.1.1

3. Check the status of NTP

1. View the NTP session information of the local device.

Display ntp-service sessions

2. View the details of the local device NTP session

Display ntp-service sessions verbose

3. View the path from the local device to the reference clock source

Display ntp-service trace

4. View the statistical information of NTP messages

Display ntp-service statistics packet

5. Check the latest 10 reasons for clock out of sync

Display ntp-service event clock-unsync

Check the latest 10 reasons why clocks are out of sync

Note: H3C devices should specify clock protocol ntp manually, otherwise they will not synchronize
