POEGEM12T2SFP User Manual 60 Alloy Computer Products Pty Ltd Copyright ©2006 3-10. DHCP Boot The POEGEM12T2SFP supports DHCP Broadcast Suppression allowing the switch to suppress
broadcast traffic. If a network loses power and then regains power and all computers on the
network boot at the same time, a lot of broadcast traffic is generated especially if all nodes on
your network are using DHCP.
The switch supports a random delay time for DHCP and boot delay for each device. This
suppresses the broadcast storm while all devices on the network are booting at the same time.
The maximum user-defined delay time is 30 seconds. If DHCP Broadcast Suppression is enabled
the delay time is set randomly, ranging from 1 to 30 seconds.
