Sanjay,
The frame relay switch will be providing multiple DLCIs to the interface,
one per point-to-point subinterface. The "frame-relay interface-dlci"
command associates the subinterface with a particular DLCI.

Yes, the Frame Relay Switch provides the DLCI, but you still need the
"frame-relay interface-dlci" command under the point-to-point subinterface.

I disagree..the Frame Relay Switch provides the DLCI.
