Managing the FCoE configuration

FCoE technology bridges the boundary between the SAN and LAN sections of your network. FCoE
configuration tasks require mostly configuration of the interface ports on the switch.
This chapter discusses the tasks for managing your FCoE configuration, login groups, and VN_port
mappings.
NOTE
To assist you in configuring FCoE, see “FCoE Initialization Protocol” on page8.

FCoE configuration guidelines and restrictions

Follow these FCoE configuration guidelines and restrictions when configuring FCoE:
The CEE configuration database is maintained in a file separate from the Fabric OS
configuration database. Fabric OS configuration management procedures remain unchanged.
FCoE to FCoE traffic across two FCOE10-24 blades can only reach 68% line rate using a
port-based routing policy. Using an exchange based routing policy can avoid the performance
drop.
Only the WWN zoning of FCoE VF ports is supported. Port-based zoning of the FCoE VF port is not
supported. Additionally, inclusion of FCoE VF ports in a zone which has port-based zone members
(such as zone members specified by their respective domain and index) is not supported. However
there are no restrictions enforced that block you from enabling the port-based zoning. If you
configure port-based zoning on a VF port, it converts all the other ports in the FCoE port group to
“session based” zoning. The only way to recover the VF port from this scenario is to set all the VF
ports in the FCoE port group offline, change the zoning config of VF ports to WWN-based zoning
and bring them back to online.
