Administrator Guide

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.
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.
FCoE MAP mode
fc-map fc-map-value
You must enter a unique MAC address prex as the FC-MAP value for each fabric.
The range is from 0EFC00 to 0EFCFF.
The default is none.
5. Congure the priority used by a server CNA to select the FCF for a fabric login (FLOGI).
FCoE MAP mode
fcf-priority priority
