Time Commands
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 client
This command enables SNTP client requests for time synchronization from NTP or SNTP
time servers specified with the sntp servers command. Use the no form to disable SNTP
client requests.
