Command Usage
◆ The SNTP and NTP clients cannot be enabled at the same time. First disable the
SNTP client before using this command.
◆ The time acquired from time servers is used to record accurate dates and times
for log events. Without NTP, the switch only records the time starting from the
factory default set at the last bootup (e.g., Dec 10 16:04:43 2014).
