Configuring an NPIV Proxy Gateway
Prerequisite: Before you configure an NPIV proxy gateway (NPG) with the FC Flex IO module on the FN IOM,
ensure that the following features are enabled.
DCB is enabled by default with the FC Flex IO module on the FN IOM.
Autonegotiated DCBx is enabled for converged traffic by default with the FC Flex IO module Ethernet
ports on all FN IOM.
FCoE transit with FIP snooping is automatically enabled when you configure Fibre Channel with the FC
Flex IO module on the FN IOM.
To configure an NPG operation with the FC Flex IO module on the FN IOM, follow these general
configuration steps:
1 Enabling Fibre Channel Capability on the Switch
2 Creating a DCB map
3 Applying a DCB map on server-facing Ethernet ports
4 Creating an FCoE VLAN
5 Creating an FCoE map
6 Applying an FCoE map on server-facing Ethernet ports
7 Applying an FCoE Map on fabric-facing FC ports
Enabling Fibre Channel Capability on the Switch
Enable the FC Flex IO module on the FN IOM that you want to configure as an NPG for the Fibre Channel
protocol. When you enable Fibre Channel capability, FCoE transit with FIP snooping is automatically enabled
on all VLANs on the switch, using the default FCoE transit settings.
1 Enable the FN IOM with the FC Flex IO module for the Fibre Channel protocol.

Creating a DCB Map
Configure the priority-based flow control (PFC) and enhanced traffic selection (ETS) settings in a DCB map
before you apply them on downstream server-facing ports on the FN IOM with the FC Flex IO module.
1 Create a DCB map to specify PFC and ETS settings for groups of dot1p priorities.
CONFIGURATION mode
dcb-map name
2 Configure the PFC setting (on or off) and the ETS bandwidth percentage allocated to traffic in each
priority group. Configure whether the priority group traffic should be handled with strict-priority
scheduling. The sum of all allocated bandwidth percentages must be 100 percent. Strict-priority traffic is
