Intel® NetStructure™ 480T Routing Switch User Guide
If the switch cannot obtain the time, it restarts the query 
process. Otherwise, the switch waits for the sntp-client 
update interval before querying again.
6 Optionally, you can change the interval for which the SNTP 
client updates the real-time clock of the switch using this com-
mand:
configure sntp-client update-interval <seconds>
The default sntp-client update-interval value is 64
7 You can verify the configuration using these commands:
show sntp-client
8 This command provides configuration and statistics associ-
ated with SNTP and its connectivity to the NTP server: 
show switch
This command indicates the GMT offset, daylight saving 
time, and the current local time.
