This is normal. v.in.dxf calculates where the text would be and draws a
box around it.

That is a known bug in v.in.dxf that might be fixed some time. You can
work around it using the Perl script in this message:

http://op.gfz-potsdam.de/GRASS-List/Archive/msg08556.html

As you have seen above v.support will delete your attribute labels
unless you run the above script first, so you will have to re-run
v.in.dxf. But that is described in the above link.

When all that is sorted out and your labels are in the dig_cats file,
d.vect.labels will be the command you want to show your text labels in
the monitor.
