Configuring the Switch
3-34
3
CLI – Use the reload command to restart the switch. When prompted, confirm that
you want to reset the switch.
Note:
When restarting the system, it will always run the Power-On Self-Test. It will also
retain all configuration information stored in non-volatile memory (See “Saving or
Restoring Configuration Settings” on page 3-21 or the copy running-config
startup-config command (See “copy” on page 4-85)).
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,
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
You can set the system time on the switch manually without using SNTP.
CLI – This example sets the system clock time and then displays the current time
and date.
Configuring SNTP
You can configure the switch to send time synchronization requests to time servers.
Command Attributes
• SNTP Client – Configures the switch to operate as an SNTP client. This requires
at least one time server to be specified in the SNTP Server field. (Default: Disabled)
• SNTP Poll Interval – Sets the interval between sending requests for a time update
from a time server. (Range: 16-16384 seconds; Default: 16 seconds)
• SNTP Server – Sets the IP address for up to three time servers. The switch
attempts to update the time from the first server, if this fails it attempts an update
from the next server in the sequence.
Web – Select SNTP, Configuration. Modify any of the required SNTP parameters,
and click Apply.
