QoS
15.1 Overview
This chapter introduces the quality of service (QoS) parameters you can configure
on the Switch.
on the Switch.
QoS is used to help solve performance degradation when there is network
congestion. The Switch allows you to use IEEE 802.1p priority tags or
Differentiated Services Code Points (DSCPs) tags to prioritize traffic.
congestion. The Switch allows you to use IEEE 802.1p priority tags or
Differentiated Services Code Points (DSCPs) tags to prioritize traffic.
15.2 What You Can Do
• Use the Port Priority screen (
) to specify IEEE 802.1p
priority for each port.
• Use the IP DiffServ (DSCP) screen (
) to configure
DSCP-based QoS settings.
• Use the Priority/Queue Mapping screen (
) to
configure IEEE 802.1p priority and queue mappings for the Switch.
• Use the Queuing Method screen (
) to configure the
weight value of each queue.
15.3 What You Need to Know
15.3.1 Queuing algorithms
Queuing algorithms allow switches to maintain separate queues for packets from
each individual source or flow and prevent a source from monopolizing the
bandwidth.
