3. SWITCH OPERATION
3.1 Address Table
The 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 Ethernet Switch.
3.2 Learning
When one packet comes in from any port, the 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 ltering for future
packets.
3.3 Forwarding & Filtering
When one packet comes from some port of the Ethernet Switching, it will
also check the destination address besides the source address learning. The
Ethernet Switching 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 Ethernet Switching 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 ltered.
Thereby increase the network throughput and availability.
3.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Storeand-Forward Ethernet Switching 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
efciency and stability.
The 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 congured in any Ethernet network environment to
signicantly boost bandwidth using conventional cabling and adapters.
9
Due to the learning function of the Ethernet switching, 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 lter
packets whose destination address is on the same segment as the source
address. This connes the network trafc to its respective domain, reducing
the overall load on the network.
The 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 Switch have built-in “Auto-negotiation”. 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 Fast Ethernet
Switch is not functioning properly, make sure the Ethernet Switch was set up
according to instructions in this manual.
Some stations cannot talk to other stations located on the other port
Solution:
The address table may contain older information than of the address
table of that node. Please power down to refresh the address
information.
Performance is bad
Solution:
Check the full duplex status of the Fast Ethernet Switch. If the Fast
Ethernet Switch is set to full duplex and the partner is set to half duplex,
then the performance will be poor.
Why the Switch doesn’t connect to the network
Solution:
Check the LNK/ACT LED on the Switch
Try another port on the 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

A.1 10/100Mbps, 10/100Base-TX
When connecting your 10/100Mbps Ethernet Switch to another switch, a
bridge or a hub, a straight or crossover cable is necessary. Each port of
the Switch supports auto-MDI/MDI-X detection. That means you can directly
connect the Switch to any Ethernet devices without making a crossover
cable. The following table and diagram show the standard RJ-45 receptacle/
connector and their pin assignments:
