N-Port Identifier Virtualization (NPIV) Proxy Gateway (NPG)
NPIV NPG feature provides Fibre Channel over Ethernet (FCoE)-FC bridging on the IOA and MXL
10/40GbE switch with the FC Flex IO module, allowing server-converged network access (CNA)
to communicate with storage area network (SAN) fabrics. In NPIV mode, the FC/Ethernet split
happens at the chassis edge, thus removing the need for an explicit external Fibre Channel
forwarder (FCF).
To configure the IOA and MXL with the FC Flex IO modules to operate as an NPIV proxy
gateway, use the following commands.
dcb-map
Create a DCB map to configure priority flow control (PFC) and enhanced transmission selection
(ETS) on Ethernet ports that support converged Ethernet traffic. Apply the DCB map to an
Ethernet interface.
Syntax
dcb-map map-name
Parameters
map-name = Enter a DCB map name. The maximum number of
alphanumeric characters is 32.
To remove a DCB map from an interface, enter the no dcb-map
map-name command in Interface Configuration mode.
Defaults
None.

Usage Information
Use the dcb-map command to specify PFC and ETS settings and apply
them to Ethernet ports.
After you apply a DCB map to an interface, the PFC and ETS settings in
the map are applied when you enable the Ethernet port.
DCBx is enabled by default.
The dcb-map command is supported only on physical Ethernet
interfaces.
