We present the plans of the CMS collaboration to measure cross sections and differential yields of charged particles (unidentified or identified pions, kaons and protons) produced in inelastic proton-proton collisions at center-of-mass energy of 14 TeV. The measurements of these basic observables could also serve as an important tool for calibrating and understanding the CMS detector at start-up. The tracking of very low transverse momentum charged particles will be possible down to about 100 MeV/c, with good efficiency and negligible fake rate. Charged hadrons can be identified down to 0.8 and 1.5 GeV/c total momentum for kaons and protons, respectively. Comparisons of the results to various theoretical models are also discussed.
