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
17
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 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 congured in any Ethernet network environment to signicantly
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 connes network trafc 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 “Autonegotiation”. 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
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 trafc 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.
