IME
The system clock can be dynamically set by polling a set of specified time
servers (NTP or SNTP). Maintaining an accurate time on the switch enables
the system log to record meaningful dates and times for event entries. If
the clock is not set, the switch will only record the time from the factory
default set at the last bootup.
SNTP Commands
sntp client
This command enables SNTP client requests for time synchronization from
NTP or SNTP time servers specified with the sntp server command. Use the
no form to disable SNTP client requests.
