Hi Hari,
This switch is L2 only and you cannot enable IP Routing. You can create L2 Vlans but you can only have 1 L3 interface for management purposes. You need a Router to connect to this switch and then run L3 SVIs on the router if you want to run Vlans. This solution is called Router-on-a-stick.
Alternatively you can go for Cisco 3550, 3560 or 3750 etc to run Intervaln/IP routing.
I am sorry to say 3548 switches are not capable to run L3 routing.
Hope This Helps

Further to the good information by Shaheen, unfortunately the the Catalyst 2900XL/3500XL/2940/2950/2970 series switches are all Layer 2 switches, and are not capable of routing or communicating between the VLANs.
The following document describes how to configure inter-vlan routing using an external router and trunk interfaces for these range of switches:-

Hope this helps..
