Time Commands
The system clock can be dynamically set by polling a set of specified NTP time
servers. Maintaining an accurate time on the switch enables the system log to
record meaningful dates and times for event entries. If the clock is not set, the switch
will only record the time from the factory default set at the last bootup.
sntp client
This command enables SNTP client requests for time synchronization from NTP or
SNTP time servers specified with the sntp servers command. Use the no form to
disable SNTP client requests.
Syntax
[no] sntp client
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
• The time acquired from time servers is used to record accurate dates and
times for log events. Without SNTP, 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
sntp servers command. It issues time synchronization requests based on the
interval set via the sntp poll command.
