4. SWITCH OPERATION
4.1 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.
4.2 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 filtering for future packets.
4.3 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 filtered. Thereby increasing the network
throughput and availability
4.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-and-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 efficiency and stability.
30
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 existence 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 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 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 Switch performs “Store and forward” therefore, no error packets occur. More reliably,
it reduces the re-transmission rate. No packet loss will occur.
4.5 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.
If attached device is: 100Base-TX port will set to:
•10Mbps, no auto-negotiation 10Mbps
•10Mbps, with auto-negotiation 10/20Mbps (10Base-T/Full-Duplex)
•100Mbps, no auto-negotiation 100Mbps
•100Mbps, with auto-negotiation 100/200Mbps
(100Base-TX/Full-Duplex)
5. TROUBLESHOOTING
This chapter contains information to help you solve problems. If the Ethernet Switch is not
functioning properly, make sure the Ethernet Switch was set up according to instructions
in this manual.
The Link LED is not lit
Solution:
Check the cable connection and remove duplex mode of the Ethernet Switch
31
Some stations cannot talk to other stations located on
The other port
Solution:
Please check the VLAN settings, trunk settings, or port enabled / disabled status.
Performance is bad
Solution:
Check the full duplex status of the Ethernet Switch. If the Ethernet Switch is set to full
duplex and the partner is set to half duplex, then the performance will be poor. Please
also check the in/out rate of the port.
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
