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.
