How can I execute tcpdump for show Number port

Hi,

I am executing the tcpdump command but the result in the port is the name but not the number of protocol, how I could execute tcpdump for show the number port and no the name?. for example:

03:32:49.447283 IP 172.16.9.65.40173 > 8.8.8.8.

domain

: 49865+[|domain]

03:32:49.495281 IP 172.16.9.65.
