ISCOM2600G-HI (A) Series Configuration Guide
SNTP
Simple Network Time Protocol (SNTP) is used to synchronize the system time of the
ISCOM2600G-HI series switch to the GMT and transmit the GMT to local time according to
the system settings of time zone. When the SNTP client and server are in different time zones,
the SNTP client will be synchronized to the GMT and then translated into the local time
according to system settings of time zone.
The SNTP client obtains time in two modes: actively sending a request packet or passively
monitoring the packet. They are implemented as below:

1.6.3 Default configurations of time management

Time and time zone
Default configurations of time and time zone are as below.
Time zone offset
Display mode of the system clock
Unicast mode: the SNTP client actively sends a request packet. After being configured
with the IP address of the SNTP unicast server, the device tries to obtain clock signals
every 10s from the SNTP server. The maximum timeout for obtaining clock signals from
the SNTP server is 60s.
Multicast or broadcast mode: SNTP client passively monitors the packet.
After being configured to multicast mode, the device monitors the multicast IP
–
address of 224.0.1.1 in real time and obtain clock signals from the SNTP multicast
server. The maximum timeout for obtaining clock signals from the SNTP server is
60s.
After being configured to broadcast mode, the device monitors the broadcast IP
–
address of 255.255.255.255 in real time and obtain clock signals from the SNTP
broadcast server. The maximum timeout for obtaining clock signals from the SNTP
server is 60s.
The time and time zone that is manually configured take effect immediately.
After NTP or SNTP is enabled, the synchronized time will override the current system
time after a synchronization period.
NTP and SNTP are mutually exclusive, so they cannot be concurrently configured.
