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. 1 p 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.
