Ports are defined by the number and the type  (udp/tcp)

So


# /usr/sbin/semanage  port -a -t http_port_t -p udp 9999
# /usr/sbin/semanage  port -m -t ntp_port_t -p udp 9999
# /usr/sbin/semanage  port -m -t ntp_port_t -p tcp 9999
/usr/sbin/semanage: Port tcp/9999 is not defined

You can change the type of a port but not the protocol.  You would have
to delete and add.  You can also NOT change the default ports that come
with policy, only ones that you add.
