Quality of Service (QoS) configuration
As a general concept, QoS is a mechanism for classifying and scheduling data traffic based on
priority settings. QoS can be used to control traffic congestion, allocate bandwidth, and carry data
traffic with different characteristics over a common interface.
Two configuration options are available:
• You can create a CEE map. A CEE map defines priority and priority group tables that support
Enhanced Transmission Selection (ETS). ETS allows allocation of bandwidth to different traffic
classes. CEE maps also allow you to enable Priority Flow Control (PFC).
• You can create a traffic class map. A traffic class map can be used to map a specific class of
traffic to a specific Class of Service (CoS).
Adding a CEE map
A CEE map defines priority and priority group tables that support Enhanced Transmission Selection
(ETS). ETS allows bandwidth to be allocated based on priority settings through an exchange of
priority group tables.
1. Select the CEE tab on the Switch Administration panel.
2. Select the QoS tab.
3. Select the CEE Maps tab (Figure 12).
