Upgrade considerations
The maximum login per switch has decreased with Fabric OS v6.4.0. When upgrading from Fabric
OS pre-v6.4.0, the configured maximum is carried forward and may exceed the v6.4.0 limit. It is
recommended to reconfigure this parameter to be within the range permitted in Fabric OS v6.4.0.
Fixed addressing mode
Fixed addressing mode is the default addressing mode used in all platforms that do not have
Virtual Fabrics enabled. When Virtual Fabrics is enabled on the Brocade DCX and DCX-4S, fixed
addressing mode is used only on the default partition. The number of NPIV devices supported on
shared area ports (48-port blades) is reduced to 64 from 128 when Virtual Fabrics mode is
enabled.
10-bit addressing mode
The 10-bit addressing mode is the default mode for all the logical switches created in the Brocade
DCX and DCX-4S enterprise-class platform. The number of NPIV or loop devices supported on a
port is 64.
