How? Why the same number for all nodes?

You can use v.category to assign unique category number to each point.
If category of given field already exists, you can either delete first
all categories of given field and assign new, for example

  v.category type=point field=2 option=del
  v.category type=point field=2 

or use another field 

  v.category type=point field=3

It is also possible to edit categories manualy in v.digit.
