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 com-

monly used to segment existing hubs, which nearly always improves over-

all performance. A Ethernet Switch can be easily configured in any 

Ethernet network environment to significantly boost bandwidth using con-

ventional cabling and adapters. 

Due to the learning function of the 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 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.

 

Auto-Negotiation 

The STP ports on the Switch have built-in "Auto-Negotiation." This tech-

nology 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 100Base-TX port in either Half- or Full-Duplex mode. 

If attached device is: 

100Base-TX port will set to: 

  10Mbps, no auto-negotiation

  10Mbps, with auto-negotiation   

10/20Mbps (10Base-T/Full-Duplex) 

  100Mbps, no auto-negotiation

 100Mbps, with auto-negotiation
