switch uses TFTP protocol.
Since TFTP protocol is not secure, it is disabled by default. If necessary, it is
possible to enable it, or change the standard UDP port (69) for another one.
For more details on configuring with Telnet, see Section 5.4.

SNTP
(Simple Network Time Protocol) is the protocol by which the switch
synchronizes its internal clock with an external time server.
The switch does not contain a built-in real-time clock, so it is necessary to use
SNTP protocol to get information about the current time. The use of SNTP protocol
is not mandatory and the main functions of the switch are not connected with SNTP.
However, to simplify administration, the switch supports the recording of the event
log in the "black box" and sending syslog and e-mail messages about the events to
the network administrator. With SNTP protocol enabled, these messages will include
a time stamp, which can be helpful for the administrator servicing the network.
Settings:

name of the server are set, IP address will prevail
Time Zone
– time zone (difference from UTC)
Period
– time period of synchronization with the server (in minutes)
Synchronize
– forced synchronization of time (to check the settings)
