The measurement of the ZZ production cross section in proton-proton collisions at center-of-mass energies of 7 and 8 TeV from data acquired by the CMS experiment at the LHC is presented. The decay channel ZZ to 2l2nu is selected from data corresponding to an integrated luminosity of 5.1 fb-1 at 7 TeV and 19.6 fb-1 at 8 TeV. The measured cross sections are in good agreement with the standard model NLO predictions. The selected data are analyzed to search for anomalous triple gauge couplings involving the ZZ final state.
