DGS-6600 Series Switch m sntp server

CLI Reference Guide

sntp server

Use this command to allow the system clock to be synchronized with the SNTP

time server. To remove a server from the list of SNTP servers, use the no form of

this command.

sntp server IP-ADDRESS

no sntp server [IP-ADDRESS]

Default Not configured.

Command Mode Global configuration.

Usage Guideline When using no sntp server without any option, the Switch will delete all

configured SNTP servers and synchronization with the SNTP server will be

disabled.

SNTP is a compact, client-only version of the NTP. SNTP can only receive the

time from NTP servers; it cannot be used to provide time services to other

systems.

SNTP typically provides time within100 milliseconds of a precise time source, but

it does not provide the complex filtering and statistical mechanisms of NTP. In

addition, SNTP does not authenticate traffic, although it can be configured with

extended access lists to provide some protection.

Enter this command once for each NTP server.

The switch must be configured with this global configuration command in order to

enable SNTP.

Create multiple SNTP servers by entering this command multiple times with

different SNTP server IP addresses.

The time obtained from the SNTP server refers to the UTC time.

Example The following example shows how to configure a switch to allow its software

clock to be synchronized with the clock by the SNTP server at IP address

192.168.22.44.

Verify the settings by entering the show sntp server command.

Syntax Description

IP-ADDRESS IP address of the time server which provides the clock synchronization.

Switch# configure terminal

Switch(config)# sntp server 192.168.22.44

Switch(config)# end
