15.3 SNTP
An administrator is unable to keep time synchronized among all the devices within a network
by changing the system clock on each device, because this is a huge work and does not
guarantee clock accuracy. NTP synchronizes timekeeping among distributed time servers and
clients to ensure high clock accuracy.
SNTP Mode: Select Service mode or Client mode. If you select Client mode, you need to
specify the IP address of the NTP server. A client sends a clock synchronization message to
the NTP servers. Upon receiving the message, the servers automatically operate in server
mode and send a reply. If Service mode is selected, switch will be used as SNTP sever to
offer time synchronization for other devices in the network.
Service IP address: IP address of SNTP server with the format of xxx.xxx.xxx.xxx.
Max Response Time: Time interval for the switch to get a response from SNTP server. It
ranges from 1 to 59 seconds, and the default value is 5 seconds.
Time Zone Offset: Time difference between Greenwich standard time and local time.
Time Offset (min): Time difference in minute between Greenwich standard time and local
time.
In Service Mode, system time can be set with year, month, day, hour, minute and second.
