The DHCP Boot 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 lose the power and then reboot and recover.
At this moment, a bunch of switch 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.
The switch 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 DHCP 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 switch itself. The default is “Disable”.
