Configure an NPIV Proxy Gateway
You can directly connect an NPIV proxy gateway to a server or a server over a FIP snooping bridge.
If you connect the S5000 and a FIP snooping bridge using a port channel, configure the port channel on
both devices (the interface port-channel command on the S5000).
NOTE: DCB is enabled by default. Auto-negotiated DCBx is enabled for converged traffic by default
on all S5000 Ethernet ports. FCoE transit with FIP snooping is automatically enabled when you
configure Fibre Channel capability (refer to Enabling Fibre Channel Capability on the Switch).
To configure NPG operation, follow these 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. Applying an FCoE Map on Server-Facing Ethernet Ports
6. Applying an FCoE Map on Fabric-Facing FC Ports
Enabling Fibre Channel Capability on the Switch
To configure as an NPG for the Fibre Channel protocol, you must first enable an S5000 switch.
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. For more information, refer to Enable FIP
Snooping on VLANs.
• Enable the switch 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 an NPG.
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 or whether priority group traffic should be handled with strict-priority scheduling.
DCB MAP mode
priority-group group_num {bandwidth percentage | strict-priority} pfc {on |
off}
The sum of all allocated bandwidth percentages must be 100%.
