Configuring Switch Mode to Fabric Services
To configure switch mode to Fabric services, use the following commands.
1. Configure Switch mode to Fabric Services.
CONFIGURATION mode
fc switch-mode fabric-services
2. Configure the SAN fabric to which the FC port connects by entering the name of the FCoE map
applied to the interface.
INTERFACE mode
fcoe-map <fcoe-map-name> {tengigabitEthernet slot/port |
fortygigabitEthernet slot/port}
The FCoE map contains FCoE and FC parameter settings (refer to FCoE Maps). Manually apply the
fcoe-map default_full_fabric to any Ethernet ports used for FCoE.
3. Configure the association between the dedicated VLAN used to carry FCoE traffic between servers
and a SAN, and the fabric where the desired storage arrays are installed.
FCOE MAP mode
fabric-id fabric-num vlan vlan-id
4. Configure the FCoE mapped address prefix (FC-MAP) value which is used to identify FCoE traffic
transmitted on the FCoE VLAN for the specified fabric.
FCOE MAP mode
fc-map fc-map-value
Name Server
Each participant in the FC environment has a unique ID, which is called the World Wide Name (WWN).
This WWN is a 64-bit address.
A Fibre Channel fabric uses another addressing scheme to address the ports in the switched fabric. Each
port in the switched fabric is assigned a 24-bit address by the FC switch. When the device logs into the
switch fabric on a specific port with its WWN, the switch assigns the port address to that port, and the
switch also maintains the correlation between the port address and the WWN address of the device on
that port. This function of the switch is implemented by using a name server, a database of objects in
which the fabric attached device registers its values.
FC-ID: 24-bit port address. Consists of three parts:
• Domain: Address of the switch itself. There are only 239 addresses available for switches in your SAN
environment. The domain number allows each switch to have a unique identifier if you have multiple
interconnected switches in your environment.
• Area: Identifies a group of F_Ports. Each group of ports has a different area number, even if there is
only one port in the group.
