Configuration manual

The show dcb command has been enhanced to display the following additional buffer-related
information:
Dell(conf)#do show dcb
dcb Status : Enabled
PFC Queue Count : 2 --Indicate the PFC queue configured.
Total buffer (lossy + lossless)(in KB): 7787--Total buffer space for lossy and
lossless queues
PFC total buffer (in KB): 6526 --Indicates the total buffer (configured or
default)
PFC shared buffer (in KB): 832--Indicates the shared buffer (Configured or
default)
PFC available buffer ( in KB): 5694--Indicates remaining available buffers for
PFC that are free to be allocated
Fibre Channel over Ethernet for FC Flex IO Modules
FCoE provides a converged Ethernet network that allows the combination of storage-area network (SAN)
and LAN traffic on a Layer 2 link by encapsulating Fibre Channel data into Ethernet frames.
The Fibre Channel (FC) Flex IO module is supported on Dell Networking Operating System (OS) MXL
10/40GbE Switch and M I/O Aggregator (IOA). The MXL and IOA 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, Interprocess 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.
FCoE works with the Ethernet enhancements provided in Data Center Bridging (DCB) to support lossless
(no-drop) SAN and LAN traffic. In addition, DCB provides flexible bandwidth sharing for different traffic
types, such as LAN and SAN, according to 802.1p priority classes of service. DCBx should be enabled on
the system before the FIP snooping feature is enabled.
All of the commands that are supported for FCoE on the MXL and I/O Aggregator apply to the FC Flex IO
modules. Similarly, all of the configuration procedures and the settings that are applicable for FCoE on
the MXL and I/O Aggregator are valid for the FC Flex IO modules.
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 M I/O Aggregator and MXL 10/40GbE Switch with the FC Flex IO module switch,
allowing server CNAs to communicate with SAN fabrics over the M I/O Aggregator and MXL 10/40GbE
Switch with the FC Flex IO module.
To configure the M I/O Aggregator and MXL 10/40GbE Switch with the FC Flex IO module to operate as
an NPIV proxy gateway, use the following commands:
