Auto-Negotiation - Planet SW-501 User Manual

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:
● 10Mbps, no auto-negotiation
● 10Mbps, with auto-negotiation
● 100Mbps, no auto-negotiation
● 100Mbps, with auto-negotiation
100Base-TX port will set to:
10Mbps
10/20Mbps (10Base-T/Full-Duplex)
100Mbps
100/200Mbps(100Base-TX/Full-Duplex)
