The Ethernet ports of the Dell M8428-k switch do not support auto-negotiation ofEthernet link speeds. The Ethernet ports only support 10-Gigabit Ethernet.• Features that are not supported on the Dell M8428-k 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- 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 OSconfiguration database. Fabric OS configuration management procedures remain unchanged.• FCoE to FCoE traffic across two FCOE10-24 blades can only reach 68% line rate using aport-based routing policy. Using an exchange-based routing policy can avoid the performancedrop.• Only WWN zoning of FCoE VF ports is supported. Port-based zoning of the FCoE VF port is notsupported. Additionally, inclusion of FCoE VF ports in a zone which has port-based zonemembers (such as zone members specified by their respective domain and index) is notsupported.
