Deployment Guide

Creating an FCoE Map
An FCoE map consists of:
• An association between the dedicated VLAN, used to carry FCoE trac, and the SAN fabric where the storage arrays are installed. Use
a separate FCoE VLAN for each fabric to which the 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 FPMA is used by servers to transmit FCoE trac
to the fabric. You can associate an FC-MAP with only one FCoE VLAN and conversely, associate an FCoE VLAN with only one FC-
MAP.
• FCF priority, the priority used by a server CNA 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 that 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. The fabric and
VLAN ID numbers must be the same. Fabric and VLAN ID range: 2–4094.
For example: fabric id 10 vlan 10
FCoE MAP mode
fabric-id fabric-num vlan vlan-id
3 Add a text description of the settings in the FCoE map. Maximum: 32 characters.
FCoE MAP mode
description text
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. Enter a unique MAC address prex as the FC-MAP value for each fabric. Range:
0EFC00–0EFCFF. Default: None.
FCoE MAP mode
fc-map fc-map-value
5 Congure the priority used by a server CNA to select the FCF for a fabric login (FLOGI). Range: 1–255. Default: 128.
FCoE MAP mode
fcf-priority priority
6 Enable the monitoring FIP keepalive messages (if it is disabled) to detect if other FCoE devices are reachable. Default: FIP keepalive
monitoring is enabled.
FCoE MAP mode
keepalive
7 Congure the time interval (in seconds) used to transmit FIP keepalive advertisements. Range: 8–90 seconds. Default: 8 seconds.
