￿“Enhanced Transmission Selection” on page 204

Enhanced Transmission Selection (ETS) provides a method for allocating link bandwidth based on the 802.1p priority value in each packet’s VLAN tag. Using ETS, different types of traffic (such as LAN, SAN, and management) that are sensitive to different handling criteria can be configured either for specific bandwidth characteristics, low-latency, or best-effort transmission, despite sharing converged links as in an FCoE environment.

￿“Data Center Bridging Capability Exchange” on page 211

Data Center Bridging Capability Exchange Protocol (DCBX) allows neighboring network devices to exchange information about their capabilities. This is used between CEE-capable devices for the purpose of discovering their peers, negotiating peer configurations, and detecting misconfigurations.
