IP-ADDRESS
Specifies the IP address of the NTP server.
Default
By default no NTP server is configured.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 15
Usage Guideline
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 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. You
must configure the switch with this command in order to enable SNTP.
You can verify your settings by entering the
show sntp
command.
Example
This example shows how to set the switch to request and accept NTP packets from
the server at 172.21.118.9.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#sntp server 172.21.118.9
DXS-3600-32S(config)#
