5.11 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 predefined connections in case the
whole building or block loses power. When this happens, the switch has to be rebooted.
Switches or other network devices on the LAN will try their best to find the server to return to
their services or try to set up the predefined links. Many broadcast packets will be issued.
The switch supports a random delay time for DHCP and boot delay for each device. This
suppresses the broadcast storm while all devices are booting at the same time. The maximum
user-defined delay time is 30 seconds. If DHCP Broadcasting Suppression function is enabled,
the delay time is set randomly, ranging from 0 to 30 seconds. The exact delay time is computed
by the switch itself. The default is Disable.
