CLI – Enter the IP address of the TFTP server, specify the source file on
the server, set the startup file name on the switch, and then restart the
switch.
If you download the startup configuration file under a new file name, you
can set this file as the startup file at a later time, and then restart the switch.
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. Without SNTP, 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 an 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.
