  Stimulated by the recent observation of the $D_2^\ast(3000)$, we study the
decay behaviors of the $3P$ and $2F$ charmed mesons in the present work. By
comparing the masses and decay properties of the $3^3P_2$ and $2^3F_2$ charmed
mesons with the observation of the $D_2^\ast(3000)$, we conclude that the most
possible assignment of the $D_2^\ast(3000)$ is the $3^3P_2$ charmed meson,
while the assignment of the $2^3F_2$ charmed meson could not be fully exclude.
The results of the unobserved $3P$ and $2F$ charmed mesons in this work could
provide some fundamental information of searching for these charmed mesons in
the further experiments by LHCb and forthcoming Belle II.
