FCoE configuration guidelines and restrictions

Follow these FCoE configuration guidelines and restrictions when configuring FCoE:

•

Speed negotiation—The Brocade 8000 switch supports auto-negotiated FC link speeds of 2, 4, 
and 8 Gbps. The Ethernet ports of the Brocade 8000 switch do not support auto-negotiation of 
Ethernet link speeds. The Ethernet ports only support 10-Gigabit Ethernet.

•

Features that are not supported on the Brocade 8000 switch or the FCOE10-24 blade:

-

Virtual fabrics

-

Admin Domains

-

Port-based zoning

-

QoS zoning

-

Adaptive networking

•

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 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.
