The following example shows only 63 NPIV devices total. Index Slot Port Address Media Speed State Proto 127 12 15 a07f40 id N4 Online FC F-Port (AoQ) 1 N Port + 63 NPIV public 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. Table 53 shows the number of NPIV devices supported on the Brocade DCX and DCX-4S enterprise-class platform. TABLE 53 Platform Number of supported NPIV devices Virtual Fabric Logical switch type NPIV support DCX Disabled N/A Yes, 127 virtual device limit.1 DCX Enabled Default switch Yes, 63 virtual device limit.1 DCX Enabled Logical switch Yes, 255 virtual device limit.2, 3 DCX Enabled Base switch No. DCX-4S Disabled N/A Yes, 255 virtual device limit.
