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 different fabrics.

When you configure an Aggregator with the 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.

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.

Configuring an NPIV Proxy Gateway

Prerequisite: Before you configure 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 traffic by default with the Ethernet ports on all

Aggregators.

• FCoE transit with FIP snooping is automatically enabled when you configure Fibre Channel on the

Aggregator.

To configure an NPG operation on an Aggregator, 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

NOTE: All these configurations are available only in PMUX mode and you cannot perform these

configurations in Standalone mode.

Default Configurations in Standalone mode

By default, the following configurations 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.
