3-8. DHCP Boot
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”.
