Table 9-1 shows the maximum number of VLANs that are supported depending on the version of code that is running and the Fabric Mode that the switch is operating in.
NOTE: Application software earlier than v5.0 does not support Fabric modes. Fabric mode 2 supports only 80-series hardware.
If the number of VLANs supported in the switch is 500, then the VLAN ID numbers used in the switch should be chosen from the range of 1 to 500 rather then 1 to 1000.
