Maybe you could wrap the snmptrap executable in a shell script.
ie. Make a shell script called snmptrap that reads in the commandline variables
and then calls the “real” snmptrap with the additional port information added.
Put the snmptrap shell script somewhere in the path ahead of the real net-snmp
executable.

Subject: Need help with snmptrapd command
HI,
I am trying to figure out a way by which I can send following trap command
without adding/mentioning the port number. The receiver is receiving the trap
when the custom port number is mentioned
snmptrap -v 2c -c rscommunity <DEST-IP-ADDRESS>:166 "" TRAP-TEST-MIB::demotraps
SNMPv2-MIB::sysLocation.0 s "some message"
By default, the following command does not require the port number to be
mentioned when the snmptrapd is using the default port-161.
snmptrap -v 2c -c rscommunity <DEST-IP-ADDRESS> "" TRAP-TEST-MIB::demotraps
SNMPv2-MIB::sysLocation.0 s "some message"
Additional info:
firewall opened for the above mentioned custom port
SELINUX
/etc/sysconfig/selinux has the following edit "SELINUX=disabled" (essentially
SELINUX is off)
So far, I have been following the
http://www.net-snmp.org/tutorial/tutorial-5/commands/snmptrap.html<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.net-2Dsnmp.org_tutorial_tutorial-2D5_commands_snmptrap.html&d=CwMFaQ&c=jcv3orpCsv7C4ly8-ubDob57ycZ4jvhoYZNDBA06fPk&r=xN9AnMDZvO_QvUZQZcoply6WFqSJuNcpv-dDu2fA4Ac&m=syhCJx6f_QiHrEJ_3yynUp8lWw1ZVzUv30Y88ft2daM&s=TzXSUtOIyBeBB7JwGqpM1HwKyI5SA6cYhZ5As2wG8kc&e=>
