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, 2015).
Note: Immediately after the switch has been powered-on, it will take up to five
minutes or more for the switch’s internal clock to acquire NTP time synchronization.
◆ 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.
Example
Console(config)#ntp client
Console(config)#
