3. SWITCH OPERATION  
3.1 Address Table  
The Fast Ethernet Switch is implemented with an address table. This  
address table composed of many entries. Each entry is used to store  
the address information of some node in network, including MAC  
address, port no, etc. This information comes from the learning process  
of Fast Ethernet Switch.  
3.2 Learning  
When one packet comes in from any port, the Fast Ethernet Switch will  
record the source address, port no. And the other related information in  
address table. This information will be used to decide either forwarding  
or filtering for future packets.  
3.3 Forwarding & Filtering  
When one packet comes from some port of the Fast Ethernet Switch,  
it will also check the destination address besides the source address  
learning. The Fast Ethernet Switch will lookup the address-table for the  
destination address. If not found, this packet will be forwarded to all  
the other ports except the port which this packet comes in. And these  
ports will transmit this packet to the network it connected. If found,  
and the destination address is located at different port from this packet  
comes in, the Fast Ethernet Switch will forward this packet to the port  
where this destination address is located according to the information  
from address table. But, if the destination address is located at the  
same port with this packet comes in, then this packet will be filtered.  
There by increasing the network throughput and availability.  
14  
 
3.4 Store-and-Forward  
Store-and-Forward is one type of packet-forwarding techniques. A  
Store-and Forward Fast Ethernet Switch stores the incoming frame in  
an internal buffer, do the complete error checking before transmission.  
Therefore, no error packets occurrence, it is the best choice when a  
network needs efficiency and stability.  
The Fast Ethernet Switch scans the destination address from the  
packet-header, searches the routing table provided for the incoming  
port and forwards the packet, only if required. The fast forwarding  
makes the Switch attractive for connecting servers directly to the  
network, thereby increasing throughput and availability. However, the  
Switch is most commonly used to segment existing hubs, which nearly  
always improves overall performance. An Ethernet Switching can be  
easily configured in any Ethernet network environment to significantly  
boost bandwidth using conventional cabling and adapters.  
Due to the learning function of the Fast Ethernet Switch, the source  
address and corresponding port number of each incoming and outgoing  
packet are stored in a routing table. This information is subsequently  
used to filter packets whose destination address is on the same  
segment as the source address. This confines network traffic to its  
respective domain, reducing the overall load on the network.  
The Fast Ethernet Switch performs “Store and Forward" therefore, no  
error packets occur. More reliably, it reduces the re-transmission rate.  
No packet loss will occur.  
3.5 Auto-Negotiation  
The STP ports on the Fast Ethernet Switch have built-in “Auto-negoti-  
ation”. This technology automatically sets the best possible bandwidth  
when a connection is established with another network device (usually  
at Power On or Reset). This is done by detect the modes and speeds at  
the second of both device is connected and capable of, both 10Base-T  
and 100Base-TX devices can connect with the port in either Half- or  
Full-Duplex mode.

4. TROUBLESHOOTING  
This chapter contains information to help you solve issues. If the Fast  
Ethernet Switch is not functioning properly, make sure the Ethernet  
Switch was set up according to instructions in this manual.  
The per port LED is not lit  
Solution:  
Check the cable connection of the Fast Ethernet Switch.  
Performance is bad  
Solution:  
Check the speed duplex mode of the partner device. The Fast Ethernet  
Switch is run at Auto-negotiation mode and if the partner is set to half  
duplex, then the performance will be poor.  
Per port LED is lit, but the traffic is irregular  
Solution:  
Check that the attached device is not set to dedicate full duplex. Some  
devices use a physical or software switch to change duplex modes.  
Auto-negotiation may not recognize this type of full-duplex setting.  
Why the Fast Ethernet Switch doesn’t connect to the network  
Solution:  
Check per port LED on the Fast Ethernet Switch. Try another port on  
the Fast Ethernet Switch Make sure the cable is installed properly Make  
sure the cable is the right type Turn off the power. After a while, turn  
on power again.
