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
- FC-SP for the FCoE ports
- Interop mode
- Access Gateway mode
- FC routing
- Integrated routing
- Hot Code Load (HCL) firmware download
- Extended fabrics
- FICON
• 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.
