NOTE: 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 first 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 traffic and SAN fabric where the storage arrays are
installed. Use a separate FCoE VLAN for each fabric to which FCoE traffic is forwarded. Any non-FCoE traffic 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
traffic 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. Configure 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 traffic from a
server on the FCoE VLAN to the FC fabric specified in Step 2.
FCoE MAP mode
fc-map fc-map-value
You must enter a unique MAC address prefix as the FC-MAP value for each fabric.
The range is from 0EFC00 to 0EFCFF.
The default is none.
5. Configure the priority used by a server CNA to select the FCF for a fabric login (FLOGI).
FCoE MAP mode
fcf-priority priority
The range is from 1 to 255.
The default is 128.
6. Enable the monitoring FIP keep-alive messages (if it is disabled) to detect if other FCoE devices are reachable.
FCoE MAP mode
keepalive
The default is FIP keep-alive monitoring is enabled.
7. Configure the time interval (in seconds) used to transmit FIP keepalive advertisements.
FCoE MAP mode
270
