Let \(A = (a_{i,j})\) be an \(n \times n\)-matrix, \(B = (b_j)\), \(C = (c_j)\) be \(n\)-column vectors, and \(d\) be a complex number. A linear fractional map of \(\mathbb C^n\) is a map of the form \(u(z) = \frac{Az + B}{\langle z,\overline{C}\rangle + d}, \) where \(\langle\cdot\,,\cdot\rangle\) is the Hermitian product in \(\mathbb C^n\). In this paper the authors characterize the cyclicity and hypercyclicity of some classes of composition operators induced by linear fractional self-maps of the unit ball \(B^n\) of \(\mathbb{C}^n\) on the Hardy space \(H^2(B^n)\), starting from the classification of linear fractional maps given by \textit{C. Bisi} and \textit{F. Bracci} [Adv. Math. 167, No. 2, 265--287 (2002; Zbl 1008.32007)] and extending and completing previous results by \textit{F. Bayart} [Adv. Math. 209, No. 2, 649--665 (2007; Zbl 1112.32002)].
