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 (i.e., 00:00:00, Jan. 1, 2001).
• This command enables client time requests to time servers specified via the
ntp servers command. It issues time synchronization requests based on the
interval set via the ntp poll command.
