Switch Features - Waters Network Systems GSM2109-1009-8PoE Operating Manual

reducing the collision domain to a single switch-port, the need for carrier sensing was
eliminated. Third, by using the store-and-forward technology's approach of inspecting
each packet to intercept corrupt or redundant data, switching eliminated unnecessary
transmissions that slow down network traffic.
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 have to be disabled for some
networking operations that involve legacy equipment. Disabling the auto-negotiation is
accomplished by hard setting the speed or duplex mode of a port.
