How do you configure more private vlans on a Cisco 3750G switch

We configured a Cisco WS-3750G-24 Port as transparent mode on VTP version 2.It only allows for 1005 vlans. Is there a tool that can we use to configure more Vlans on the device,do we need to upgrade the software?

3750 support 1005 vlans (both normal and extended range). You can use extended range 1006-4094 IDs for vlans but you cannot have more than total of 1000 vlans on your switch. Consider usind "sdm prefer" if have many vlans and no routing.

If you want to configure more than 1000 vlans cisco catalyst models are 6500, 4500, 4900, 4849 and nexus 7k,5k, 3k.
