sntp server

This command is used to allow the system clock to be synchronized with an SNTP time server. To
remove a server from the list of SNTP servers, use the no form of this command.
sntp server {IP-ADDRESS | IPV6-ADDRESS} [vrf VRF-NAME]
no sntp server {IP-ADDRESS | IPV6-ADDRESS} [vrf VRF-NAME]
Parameters
IP-ADDRESS
IPV6-ADDRESS
VRF-NAME
Default
None.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
SNTP is a compact, client-only version of the NTP. Unlike 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
within 100 milliseconds of the accurate time, but it does not provide the complex filtering and statistical
mechanisms of NTP. In addition, SNTP does not authenticate traffic, although you can configure
extended access lists to provide some protection.
Enter this command once for each NTP server. Configure the system with either this command or the
sntp broadcast client global configuration command in order to enable SNTP. Create multiple SNTP
servers by enter this command multiple times with different SNTP server IP addresses.
Use the no command to delete the SNTP server entry. To delete an entry, specify the information exactly
the same as the originally configured setting. The time obtained from the SNTP server refers to the UTC
time.
Example
This 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.
Switch# configure terminal
Switch(config)# sntp server 192.168.22.44
Switch(config)#
Specifies the IP address of the time server which provides the clock
synchronization.
Specifies the IPv6 address of the time server.
Specifies the name of the routing forwarding instance.
