Traffic Prioritization - Cisco SG 100D-08 Quick Start Manual

Welcome
Thank you for choosing the Cisco SG 100D-08 Unmanaged Switch, a
Cisco Small Business network communications device.
This guide will familiarize you with the layout of the unmanaged switch and
describe how to deploy the device in your network. For additional
information, see www.cisco.com/smb.
Network Speed and Auto MDI/MDI-X Detection
All ports support network speed auto-negotiation and auto MDI/MDI-X
crossover detection. Network speed auto-negotiation automatically
selects the best connection speed and mode (half- or full-duplex) for
communicating with attached devices. Auto MDI/MDI-X crossover
detection automatically adjusts for the cable type (straight-through or
crossover) used to connect the unmanaged switch to other devices.
Green Energy Savings Technology
Green Ethernet Technology saves energy by entering sleep mode on a
Cisco SG 100D-08 port while there is no connection or the device
connected to that switch port is turned off.

Traffic Prioritization

The Cisco SG 100D-08 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, VLAN tagged
frames.) This ensures that time-sensitive traffic gets the highest level of
service.
