Concept Guide
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 Congure 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 trac from a server on
the FCoE VLAN to the FC fabric specied in Step 2. Enter a unique MAC address prex as the FC-MAP value for each fabric. Range:
0EFC00–0EFCFF. Default: None.
FCoE MAP mode
fc-map fc-map-value
5 Congure 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 Congure the time interval (in seconds) used to transmit FIP keepalive advertisements. Range: 8–90 seconds. Default: 8 seconds.
FCoE MAP mode
fka-adv-period seconds
Applying an FCoE Map on Server-facing Ethernet Ports
You can apply multiple FCoE maps on an Ethernet port or port channel. When you apply an FCoE map on a server-facing port or port
channel:
• The port is congured to operate in hybrid mode (accept both tagged and untagged VLAN frames).
• The associated FCoE VLAN is enabled on the port or port channel.
When you enable a server-facing Ethernet port, the servers respond to the FIP advertisements by performing FLOGIs on upstream
virtualized FCF ports. The NPG forwards the FLOGIs as FDISC messages to a SAN switch.
