POEGEM12T2SFP User Manual

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.
