Is the Shabbat boundary limit (techum) of two thousand cubits a Torah-level or rabbinic prohibition?

ShabbatTechum Shabbat

Synopsis

The Mechaber sets the two-thousand-cubit limit as rabbinic, while the Rambam holds that a twelve-mil limit (the extent of the Israelite camp) is a Torah-level prohibition. Most later Ashkenazi authorities side with the majority view that there is no Torah-level prohibition at all.
