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 to any Ethernet ports used for FCoE.
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.
•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.
•Port: Provides 256 addresses for identifying attached N_Ports and NL_Ports.
The following sequence explains the operation for the attached N_Port:
• N_Port sends a Fabric Login (FLOGI) as it requests a unique 24-bit address from the Fabric Login
Server.
• N_Port sends FLOGI to address 0xFFFFFE. Upon success, it obtains a valid address (FCID).
• N_Port sends a Port Login (PLOGI) to inform the Fabric Name Server of its personality and capabilities,
this includes WWNN, WWPN.
• N_Port sends PLOGI to address 0xFFFFFC to register this address with the name server.
Command Description
show fc ns
switch
Display all the devices in name server database of the switch.
show fc ns
switch brief
Displays the local name server entries — brief version.
The following configurations are applicable only after configuring the switch mode to FCF Port mode
using the feature fc fport domain id 2 command. When you set Switch mode to FCF Port mode,
any previously configured fcoe-map is removed.
