P-660H-T1v3s User’s Guide

The following table lists some commonly-used services and their associated 
protocols and port numbers.

• Name: This is a short, descriptive name for the service. You can use this one or 

create a different one, if you like.

• Protocol: This is the type of IP protocol used by the service. If this is TCP/

UDP, then the service uses the same port number with TCP and UDP. If this is 

USER-DEFINED, the Port(s) is the IP protocol number, not the port number.

• Port(s): This value depends on the Protocol.

• If  the  Protocol is TCP, UDP, or TCP/UDP, this is the IP port number.
• If  the  Protocol is USER, this is the IP protocol number.

• Description: This is a brief explanation of the applications that use this service 

or the situations in which this service is used.
