Naming conventions in port descriptions

Resource Monitoring

Monitoring Network Resources : Discovering and monitoring TCP and UDP ports : Reviewing the list of well-known ports : Naming conventions in port descriptions

If a port number is one of the registered well-known numbers, a short description of the port appears as the port's name. (Once you create a resource monitor for a port, OpenEdge Management displays this descriptive information on the resource monitoring page, under the page title.)

The following table identifies names associated with several well-known TCP and UDP port numbers.

Table 9. Well-known ports and their associated names
Well-known port	Description field acronym
TCP Port 21	FTP
TCP Port 23	Telnet
TCP Port 25	SMTP
TCP Port 80	HTTP
TCP Port 110	POP3
TCP Port 119	NNTP
TCP Port 143	IMAP
TCP Port 389	LDAP
TCP Port 547	DHCPv6
UDP Port 53	DNS
UDP 161	SNMP

If a port is not considered well known, OpenEdge Management displays a port name in the Description field that is based on a combination of the port number and the protocol type you specify. For example, if you specify the port type as TCP and the port number as 3510, OpenEdge Management displays the port name as tcp3510.
