4.3.1. Broadcast Storm Control
The switch implements a broadcast storm control mechanism. Check the ports next to
Enable Port
to select
ports that will drop incoming broadcast packets if the number of received broadcast packets reaches the threshold
defined. Each port
’s broadcast storm protection function can be enabled individually.
Figure 17 - Configure broadcast storm control
Broadcast packets are only checked at selected ports. Timing is set to 500 us for 10Mbps speed and 5ms for
100Mbps. Excess broadcast packets will be discarded. Packets for un-selected ports are treated as normal traffic.
Threshold: Type in a threshold between
1
and
63
to limit the maximum byte counts which a port can send or
receive during a period of time.
Enable Port: Checked ports will stop transmitting or receiving data when their thresholds given in Threshold
are reached. Unchecked ports will function normally.

4.4.1. PoE Introduction
Based on the global standard IEEE 802.3af, PoE is a technology for wired Ethernet. PoE allows the electrical
power necessary for the operation of each end-device (IP Cameras, VoIP phones, etc) to be carried by data cables
rather than by separate power cords. Such a network configuration helps enterprises improve productivity by
minimizing the number of wires that must be used to install the network, thus incurring lower cost, and less power
failures. In the case of surveillance technology, IP cameras and access systems may be installed throughout a
facility without incurring costs associated with hiring an electrician.
Providing up to 24 PoE, in-line power interface, the switch can easily build a power central-controlled IP phone
system, IP Camera system or AP group for the enterprise. For instance, 24 camera / AP can be easily installed
around the corner in the company for surveillance demands or build a wireless roaming environment in the office.
Without the power-socket limitation, the PoE Switch makes the installation of cameras or WLAN AP easy and
efficient.
