Setting the System Clock
Simple Network Time Protocol (SNTP) or Network Time Protocol (NTP) can
be used to set the switch’s internal clock based on periodic updates from a
time server. Maintaining an accurate time on the switch enables the system
log to record meaningful dates and times for event entries. You can also
manually set the clock. If the clock is not set manually or via SNTP or NTP, the
switch will only record the time from the factory default set at the last bootup.
When the SNTP client is enabled, the switch periodically sends a request for a
time update to a configured time server. You can configure up to three time
server IP addresses. The switch will attempt to poll each server in the
configured sequence.
The switch also supports the following time settings:
◆
Time Zone – You can specify the offset from Coordinated Universal Time
(UTC), also known as Greenwich Mean Time (GMT).
