CLI – Use the reload command to reboot the system.
Note: When restarting the system, it will always run the Power-On Self-Test.
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 using the CLI. (See
“calendar set” on page 3-40.) If the clock is not set, the switch will only record the
time from the factory default set at the last bootup.
This switch acts as an SNTP client in two modes:
Unicast – 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.
Broadcast – The switch sets its clock from a time server in the same subnet that
broadcasts time updates. If there is more than one SNTP server, the switch accepts
the first broadcast it detects and ignores broadcasts from other servers.
Configuring SNTP
You can configure the switch to send time synchronization requests to specific time
servers (i.e., client mode), update its clock based on broadcasts from time servers,
or use both methods. When both methods are enabled, the switch will update its
clock using information broadcast from time servers, but will query the specified
server(s) if a broadcast is not received within the polling interval.
Command Attributes
• SNTP Client – Configures the switch to operate as an SNTP unicast client. This
mode requires at least one time server to be specified in the SNTP Server field.
