Dell PowerEdge FN I/O Module Command Line Reference Guide 9.10(0.0)

Data center bridging (DCB) refers to a set of IEEE Ethernet enhancements that provide data centers with a single, converged network to support multiple traffic types, including local area network (LAN), server, and storage traffic.

The Fibre Channel (FC) Flex IO module is supported on switch. The switch installed with the FC Flex IO module functions as a top-of-rack edge switch that supports converged enhanced ethernet (CEE) traffic — Fibre Channel over Ethernet (FCoE) for storage, inter-process communication (IPC) for servers, and Ethernet local area network (LAN) (IP cloud) for data — and FC links to one or more storage area network (SAN) fabrics.

The dcb-input and dcb-output configuration commands are deprecated, starting with Dell Networking OS Release 9.3(0.0) on the Dell switches. Use the dcp-map command to create a DCB map to configure priority flow control (PFC) and enhanced transmission selection (ETS) on Ethernet ports that support converged Ethernet traffic.

The Dell Networking Operating System (OS) commands for the DCB features include 802.1Qbb priority-based flow control (PFC), 802.1Qaz enhanced transmission selection (ETS), and the data center bridging exchange (DCBX) protocol.
