Set the port number in snmp.conf?
defaultPort PORT
defines the default UDP port that client SNMP
applications will attempt to connect to. This can be overridden by
explicitly including a port number in the AGENT
specification. See the snmpcmd(1) manual page for more details.
If not specified, the default value for this token is 161.
