FS S3400-48T4SP PoE+ Switch NTP Configuration

1. Overview

Network Time Protocol (NTP) is a computer time synchronization protocol used for time synchronization between distributed time servers and clients. It offers accurate time correction and protection against malicious protocol attacks through encrypted authentication. Clients and servers communicate via User Datagram Protocol (UDP) on port 123.

1.1 Stipulation

1.1.1 Format Stipulation in the Command Line

Syntax	Meaning
Bold	Represents keywords in the command line that remain unchanged and must be entered exactly as shown.
{italic}	Represents parameters in the command line that must be replaced with actual values, presented in italics within braces.
`<italic>`	Represents parameters in the command line that must be replaced with actual values, presented in italics within angle brackets.
`[]`	Indicates optional parameters.
`{x\|y\|...}`	Allows selection of one option from two or more choices.
`[x\|y\|...]`	Allows selection of one option or none from two or more choices.
`{ x \| y \|... }*`	Requires selection of at least one option from two or more, or all options.
`[x\|y\|...]*`	Allows selection of multiple options or none from two or more choices.
`<1-n>`	Indicates that the parameter preceding the '&' symbol can be entered 1 to n times.
`#`	Denotes an explanation line starting with the '#' symbol.

2. NTP Configuration

2.1 Overview

2.2 NTP Configuration

2.2.1 Configure the Equipment as an NTP Server

Configuration mode: Global

Command	Purpose
`ntp master primary`	Configures the equipment as the primary NTP server (stratum = 1) if it does not have an upper-level NTP server.
`ntp master secondary`	Configures the equipment as a secondary NTP server if it has an upper-level NTP server. Note: The equipment cannot provide time synchronization service for NTP clients unless the `ntp server` command is configured and time synchronization is achieved with designated servers.

2.2.2 Configure NTP Authentication Function

Configuration mode: Global

Command	Purpose
`ntp authentication enable`	Enables the authentication function, which is disabled by default.
`ntp authentication key keyid md5 password`	Configures the NTP MD5 authentication key ID and its corresponding password.
`ntp authentication trusted-key keyid`	Configures the key ID corresponding to the key as a trusted key.

2.2.3 Configure NTP Association

Configuration mode: Global

Command	Purpose
`ntp server ip-address [version number \| key keyid]*`	Configures the IP address of the NTP server, with optional designation of version number, key number, and encryption key.
`ntp peer ip-address [version number \| key keyid]*`	Configures the NTP peer IP address of the device, with optional designation of version number and key number.

Usage Guidelines:

Equipment can provide time services for NTP clients only after achieving time synchronization. Otherwise, client devices using the equipment as their server will not achieve time synchronization.
For NTP authentication, both parties must enable the NTP authentication function simultaneously, configure the same key ID and key, and designate the key ID as trusted. Failure to do so will result in failed time synchronization.
