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.
The following table displays the options on this page:
