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
