3. Switch Operation
3.1 Address Table
The Gigabit 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 Gigabit Ethernet Switch.
3.2 Learning
When one packet comes in from any port. The Gigabit 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 ltering for future
packets.
3.3 Forwarding & Filtering
When one packet comes from some port of the Gigabit Ethernet Switch, it will also
check the destination address besides the source address learning. The Gigabit
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 Gigabit 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 ltered. Thereby increasing the network
throughput and availability.
3.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-and
Forward Gigabit 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 efciency and stability.
The Gigabit 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

13
congured in any Ethernet network environment to signicantly boost bandwidth
using conventional cabling and adapters.
Due to the learning function of the Gigabit 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 lter packets whose
destination address is on the same segment as the source address. This connes
network trafc to its respective domain, reducing the overall load on the network.
The Gigabit 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 Gigabit Ethernet 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. 1000Base-T can be only connected in Full-
duplex mode.

4.Troubleshooting
This chapter contains information to help you solve issues. If the Gigabit Ethernet
Switch is not functioning properly, make sure the Gigabit 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 Gigabit Ethernet Switch.
Performance is bad
Solution
Check the speed duplex mode of the partner device. The Gigabit
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 trafc 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 Gigabit Ethernet Switch doesn’t connect to the network
Solution
Check per port LED on the Gigabit Ethernet Switch. Try another
port on the Gigabit 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.
