Service Manual

NOTE: In each FCoE map, the fabric ID, FC-MAP value, and FCoE VLAN must be unique. To access one
SAN fabric, use one FCoE map. You cannot use the same FCoE map to access different fabrics.
When you configure an S5000 as an NPG, FCoE transit with FIP snooping is automatically enabled and
configured using the parameters in the FCoE map applied to server-facing Ethernet and fabric-facing FC
interfaces (refer to FIP Snooping on an NPIV Proxy Gateway).
After you apply an FCoE map on an FC port, when you enable the port (using the no shutdown command),
the NPG starts sending FIP multicast advertisements on behalf of the FC port to downstream servers to
advertise the availability of a new FCF port on the FCoE VLAN. The FIP advertisement also contains a keepalive
message to maintain connectivity between a SAN fabric and downstream servers.
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.
