Addendum

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 MXL 10/40GbE Switch and M I/O Aggregator with the FC Flex IO module 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 (see FIP Snooping on an NPIV
Proxy Gateway).
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 on an MXL 10/40GbE Switch and M I/O
Aggregator with the FC Flex IO module:
DCB is enabled by default on the MXL 10/40GbE Switch and M I/O Aggregator with the FC Flex IO
module. Auto-negotiated DCBx is enabled for converged traffic by default on all MXL 10/40GbE Switch
and M I/O Aggregator with the FC Flex IO module Ethernet ports. FCoE transit with FIP snooping is
automatically enabled when you configure Fibre Channel capability on the MXL 10/40GbE Switch and M
I/O Aggregator with the FC Flex IO module (see Enabling Fibre Channel Capability on the Switch).
To configure NPG operation on an MXL 10/40GbE Switch and M I/O Aggregator with the FC Flex IO
module, 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.
Enabling Fibre Channel Capability on the Switch
You must first enable an MXL 10/40GbE Switch and M I/O Aggregator with the FC Flex IO module that
you want to configure as an NPG for the Fibre Channel protocol. 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, see Enabling FIP Snooping on VLANs.

CONFIGURATION
Creating a DCB map
Configure the priority-based flow control (PFC) and enhanced traffic selection (ETS) settings in a DCB
map before you can apply them on downstream server-facing ports on an MXL 10/40GbE Switch and M
I/O Aggregator with the FC Flex IO module NPG.
