Administrator Guide

An FCoE map applies the following parameters on server-facing Ethernet and fabric-facing FC ports:
• The dedicated FCoE VLAN used to transport FCoE storage trac.
• The FC-MAP value used to generate a fabric-provided MAC address.
• The association between the FCoE VLAN ID and FC fabric ID where the desired storage arrays are installed. Each Fibre Channel fabric
serves as an isolated SAN topology within the same physical network.
• A server uses the priority to select an upstream FCoE forwarder (FCF priority).
• FIP keepalive (FKA) advertisement timeout.
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 dierent fabrics.
When you congure an S5000 as an NPG, FCoE transit with FIP snooping is automatically enabled and congured 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.
Congure 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, congure 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 trac by default on all S5000 Ethernet ports.
FCoE transit with FIP snooping is automatically enabled when you congure Fibre Channel capability (refer to Enabling Fibre
Channel Capability on the Switch).
To congure NPG operation, follow these conguration 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 congure as an NPG for the Fibre Channel protocol, you must rst 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.
