commands of the Fiber Channel (FC) Flex IO module.
Data Center Bridging (DCB) for FC Flex IO Modules
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 MXL 10/40GbE Switch. The MXL 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 — as well as 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 MXL 10/40GbE Switch platform. 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.
Interworking of DCB Map With DCB Buffer Threshold Settings
DCB map functionality is supported on the MXL platform.
The dcb-input and dcb-output configuration commands are deprecated. You must 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.
Configure the dcb-buffer-threshold command and its related parameters only on ports with either
auto configuration or dcb-map configuration. This command is not supported on existing front-panel
interfaces or stack ports that are configured with the dcb-input or dcb-output commands. Similarly, if
