FC Flex IO Modules
This part provides a generic, broad-level description of the operations, capabilities, and configuration 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 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.
NPIV Proxy Gateway for FC Flex IO Modules
The N-port identifier virtualization (NPIV) Proxy Gateway (NPG) feature provides FCoE-FC bridging capability on the MXL 10/40GbE
Switch with the FC Flex IO module switch, allowing server CNAs to communicate with SAN fabrics over the MXL 10/40GbE Switch with
the FC Flex IO module.
To configure the MXL 10/40GbE Switch with the FC Flex IO module to operate as an NPIV proxy gateway, use the following commands:
