1. I troductio
Welcome to the World of Network Switching. n modern business,
communication and information sharing are fundamental to success.
Computer networks have proven to be one of the fastest ways of
communication.
The SmartGST-2402 is a multi-port Switch that can be used to build high-
performance switched workgroup networks. t is a store-and-forward device
that offers low latency for high-speed networking and is targeted at
workgroup, department, or backbone computing environments.
Figure 1-1. SmartGST-2402
The SmartGST-2402's “store-and-forward“ switching scheme allows the
switch to auto-learn and store source address in an 8K-entry MAC address
table.
MDI (Medium Dependent nterface) Port is also called an "uplink port". The
MD port does not cross the transmission and reception lines, which is done
by the regular ports (MD -X ports) that connect to end stations. n general,
MDI means connecting to another Hub or Switch while MDIX means
connecting to a workstation or PC. Therefore, Auto MDI/MDIX means that
you can connect to another Switch or workstation without changing non-
crossover or crossover cabling.
The SmartGST-2402 has twenty four auto-sensing 10/100Base-TX RJ-45
ports plus one module slot for optional dual port 100Base-FX, 1000T, and
1000SX/LX Mini GB C modules. This enables hi

Ether et Switchi g Tech ology
Ethernet Switching Technology dramatically boosted the total bandwidth of a
network, eliminated congestion problems inherent with CSMA/CD (Carrier
Sense multiple access with Collision Detection) protocol, and greatly reduced
unnecessar
y
transmissions.

This revolutionized networking. First, by allowing two-way, simultaneous
transmissions over the same port (Full-duplex), which essentially doubled the
bandwidth. Second, by reducing the collision domain to a single switch-port,
which eliminated the need for carrier sensing. Third, by using the store-and-
forward technology’s approach of inspecting each packet to intercept corrupt
or redundant data. By employing address learning, this switching eliminated
unnecessary transmission that slowed the network.
Auto-negotiation regulates the speed and duplex of each port, based on the
capability of both devices. Flow-control allows transmission from a 100Mbps
node to a 10Mbps node without loss of data. Auto-negotiation and flow-control
may need to be disabled for some networking operations involving legacy
equipment. Disabling the auto-negotiation is accomplished by fixing the speed
or duplex of a port.
Ethernet Switching Technology supplies higher performance at lower costs
than other solutions. Wider bandwidth, no congestion, and the reduction in
traffic is why switching is replacing expensive routers and inefficient hubs as
the ultimate networking solution. Switching brings a whole new way of thinking
to networking.
