QoS configuration

QoS configuration involves configuring packet classification, mapping the priority and traffic class,

controlling congestion, and scheduling. The configuration of these QoS entities consist of CEE Map

and Traffic Class Map configuration.

In a Converged Enhanced Ethernet (CEE) configuration, Enhanced Transmission Selection (ETS)

and Priority-based flow control (PFC) are configured by utilizing a priority table, a priority group

table, and a priority traffic table. The Traffic Class Map is the mapping of user priority to traffic

class.

Enhanced Transmission Selection

Enhanced Transmission Selection (ETS) allows lower priority traffic classes to use available

bandwidth not being used by higher priority traffic classes and maximizes the use of available

bandwidth.
