What command, exactly, did you issue to send this message?

Ok. I am assuming that you ran this from the command line. Did it say
anything on standard output/standard error?
What happened if you did use port number 162?
If you adds the flag -d, does it say anything then?

Agreed.

Since you are running a user tool it defaults to logging on standard
error. You can redirect the logs to a file with -Lf <filename> or to
syslog with -Ls. From the man page snmpcmd(1):
LOGGING OPTIONS
The mechanism and destination to use for logging of warning and
error messages can be controlled by passing various parameters
to the -L flag.
-Le Log messages to the standard error stream.
-Lf FILE
Log messages to the specified file.
-Lo Log messages to the standard output stream.
-Ls FACILITY
Log messages via syslog, using the specified facility
('d' for LOG_DAEMON, 'u' for LOG_USER, or '0'-'7' for
LOG_LOCAL0 through LOG_LOCAL7).
