Setting the System Clock
Simple Network Time Protocol (SNTP) allows the switch to set its internal clock
based on periodic updates from a time server (SNTP or NTP). 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, 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.
Setting the Time
Manually
Use the System > Time (Configure General - Manual) page to set the system time on
the switch manually without using SNTP.
Parameters
The following parameters are displayed:
◆ Current Time – Shows the current time set on the switch.
◆ Hours – Sets the hour. (Range: 0-23)
◆ Minutes – Sets the minute value. (Range: 0-59)
◆ Seconds – Sets the second value. (Range: 0-59)
◆ Month – Sets the month. (Range: 1-12)
◆ Day – Sets the day of the month. (Range: 1-31)
◆ Year – Sets the year. (Range: 1970-2037)
