FCoE Maps
An FCoE map is used to identify the SAN fabric to which FCoE storage trac is sent. Using an FCoE map, an Aggregator with the NPG
operates as an FCoE-FC bridge between an FC SAN and FCoE network by providing FCoE-enabled servers and switches with the
necessary parameters to log in to a SAN fabric.
An FCoE map applies the following parameters on server-facing Ethernet and fabric-facing FC ports on the Aggregator:
• 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.
• The priority used by a server 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. Use one FCoE map to access one SAN fabric. You
cannot use the same FCoE map to access dierent fabrics.
When you congure an Aggregator with the 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.
After you apply an FCoE map on an FC port, when you enable the port (no shutdown), the NPG starts sending FIP multicast
advertisements on behalf of the FC port to downstream servers in order 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guring an NPIV Proxy Gateway
Prerequisite: Before you congure an NPIV proxy gateway (NPG) on an Aggregator, ensure that the following features are enabled.
• DCB is enabled by default on the Aggregator.
• Autonegotiated DCBx is enabled for converged trac by default with the Ethernet ports on all Aggregators.
• FCoE transit with FIP snooping is automatically enabled when you congure Fibre Channel on the Aggregator.
To congure an NPG operation on an Aggregator, follow these general 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 Creating an FCoE map
6 Applying an FCoE map on server-facing Ethernet ports
7 Applying an FCoE Map on fabric-facing FC ports
NOTE
: All these congurations are available only in PMUX mode and you cannot perform these congurations in Standalone
mode.
Default
Congurations in Standalone mode
By default, the following congurations are set in Standalone mode:
1 All the FC port are applied with the default FCoE map.
2 All the 10G server facing ports with the DCBX frames will have the default FCoE map and default DCB map assigned, and without the
DCBX frames, DCB_MAP_PFC_OFF will be applied.
