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 trac types, including local area network (LAN), server, and storage trac.
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) trac — 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 conguration 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 congure priority ow control (PFC) and enhanced transmission
selection (ETS) on Ethernet ports that support converged Ethernet trac.
The Dell Networking Operating System (OS) commands for the DCB features include 802.1Qbb priority-based ow 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 identier virtualization (NPIV) Proxy Gateway (NPG) feature provides FCoE-FC bridging capability on the system with the FC
Flex IO module switch, allowing server CNAs to communicate with SAN fabrics over the FN IOM with the FC Flex IO module.
To congure the FN IOM with the FC Flex IO module to operate as an NPIV proxy gateway, use the following commands:
