Users Guide

• 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.
When you congure an M I/O Aggregator 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.
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.
After removing and reapplying the fabric map or after modifying the FCoE map, the Fiber Channel (FC) devices do not re-login. To mitigate
this issue, you must rst run the shut command and then the no shutdown command on each member interface after you alter the FCOE
map.
Creating an FCoE Map
An FCoE map consists of the following elements.
• An association between the dedicated VLAN used to carry FCoE trac and SAN fabric where the storage arrays are installed. Use a
separate FCoE VLAN for each fabric to which FCoE trac is forwarded. Any non-FCoE trac sent on a dedicated FCoE VLAN is
dropped.
• The FC-MAP value used to generate the fabric-provided MAC address (FPMA). The server uses the FPMA to transmit FCoE trac to
the fabric. You can associate an FC-MAP with only one FCoE VLAN and vice versa.
• FCF priority: a CNA server uses the priority to select an upstream FCoE forwarder (FCF).
• FIP keepalive (FKA) advertisement timeout.
The values for the FCoE VLAN, fabric ID, and FC-MAP must be unique. Apply an FCoE map on downstream server-facing Ethernet ports
and upstream fabric-facing Fibre Channel ports.
1 Create an FCoE map which contains parameters used in the communication between servers and a SAN fabric.
CONFIGURATION mode
fcoe-map map-name
2 Congure the association between the dedicated VLAN and the fabric where the desired storage arrays are installed.
FCoE MAP mode
fabric-id fabric-num vlan vlan-id
The fabric and VLAN ID numbers must be the same.
The fabric and VLAN ID range is from 2 to 4094.
For example:
fabric id 10 vlan 10
3 Add a text description of the settings in the FCoE map.
FCoE MAP mode
description text
The maximum is 32 characters.
4 Specify the FC-MAP value used to generate a fabric-provided MAC address, which is required to send FCoE trac from a server on
the FCoE VLAN to the FC fabric specied in Step 2.
