4-4-4. Broadcasting Suppression
Function name:
Broadcasting Suppression
Function description:
The Broadcasting Suppression function is used to spread the request
broadcast packet into a bigger time frame to prevent the traffic congestion due
to broadcast packets from many network devices which may seek its NMS,
boot server, DHCP server and many connections predefined when the whole
building or block loses the power and then reboot and recover. At this moment,
a bunch of converter or other network device on the LAN will try its best to find
the server to get the services or try to set up the predefined links, they will
issue many broadcast packets in the network.
Signamax 065-1600 series supports a random delay time for DHCP and boot
delay for each device. This suppresses the broadcast storm while all devices
are at booting stage in the same time. The maximum user-defined delay time
is 30 sec. If Broadcasting Suppression function is enabled, the delay time is
set randomly, ranging from 0 to 30 seconds, because the exactly delay time is
computed by the converter itself. The default is “Disable”.
