Cisco SF100D-05 Quick Start Guide - Page 2

Welcome Thank you for choosing the Cisco SF 100D-05, SF 100D-08, SF 100D-16, or SG 100D-08 Unmanaged Desktop Switch, a Cisco Small Business network communications device. Green Energy-Efficient Technology The Cisco SG 100D-08 switch supports Green Energy-efficient Technology. It can enter sleep mode, turn off unused ports, and adjust power as needed. This increases energy efficiency to help businesses use less power and save money. Traffic Prioritization Traffic Prioritization delivers Quality of Service (QoS); all received packets are examined for QoS priority encoding. The switch reads the priority level and forwards the packet based on that priority level. For example, during heavy loads voice and video traffic are given priority over data traffic. The switch is configured to comply with 802.1p tagged frames. This ensures that time-sensitive traffic gets the highest level of service. To prioritize voice or video traffic by using the QoS feature on the unmanaged desktop switch, set flow control to off in the configurations of the connected devices. Otherwise, flow control might send a pause frame to the switch, blocking the high-priority QoS packets queued on the port. On some devices, such as some IP phones and IP cameras, flow control might not be configurable. Jumbo Frame Support The Cisco SG 100D-08 switch supports frames up to 9,000 bytes called jumbo frames. Jumbo Frame support improves network throughput and reduces CPU utilization during large file transfers, such as multimedia files, by allowing larger payloads in each packet. 1 Unmanaged Desktop Switch
