DCB configuration management

Depending on the platform, the DCB switch has one of the configurations shown in Table 53.

You must configure DCB interfaces and ports differently than you configure Fibre Channel ports to effectively use the converged network features.

For example, priority-based flow control (PFC) and Enhanced Transmission Selection (ETS) are the two QoS policy enhancements you must configure to create a lossless Ethernet. You then use DCBX protocol on DCB-enabled devices to exchange configuration information.

The DCB ports of FOS DCB devices are categorized into two types:

•External ports - The eight external ports are the same as the original 10 Gbps Ethernet DCB ports. The default name in the device tree is ExT <slot>/<port>.

•Internal ports - The default name for the 12 or 14 internal ports is InT <slot>/<port>. 802.1x, LAG configuration, and Spanning Tree Protocol (STP) are not supported on internal ports.
