- /**
- * This is an example program to explain how to write an application to send a
- * v1 Trap message using com.adventnet.snmp.snmp2 and com.adventnet.snmp.mib
- * packages of AdventNetSNMP2 api.
- * The user could run this application by giving any one of the following usage.
- *
- * java snmpv1trap [options] [-m mibfile] hostname enterprise-oid agent-addr generic-trap specific-trap
- * timeticks [OID value] ...
- *
- * java snmpv1trap [-d] [-c community] [-p port] [-m MIB_files] host enterprise agent-addr generic-trap specific-trap timeticks [OID value] ...
- * e.g.
- * java snmpv1trap -p 162 -c public [-m ../../../mibs/RFC1213-MIB] adventnet 1.2.0 adventnet 0 6 1000 1.5.0 advent
- *
- * If the oid is not starting with a dot (.) it will be prefixed by .1.3.6.1.2.1 .
- * So the entire OID of 1.1.0 will become .1.3.6.1.2.1.1.1.0 . You can also
- * give the entire OID .
- *
- * Since the mib is loaded you can also give string oids in the following formats
- * .iso.org.dod.internet.mgmt.mib-2.system.sysDescr.0 or system.sysDescr.0 or
- * sysDescr.0 .
- *
- * Options:
- * [-d] option Debug output. By default off.
- * [-c] option community String. By default "public".
- * [-p] option remote port no. By default 162.
- * [-m] option MIB files to be loaded. Used to find the type of object.
- * enterprise Object Identifier (sysObjectID for generic traps)
- * agent-addr the IP address of the agent sending the trap
- * generic-trap generic trap type INTEGER (0..6)
- * specific-trap specific code INTEGER(0..2147483647)
- * timeticks the value of object sysUpTime when the event occurred
- * host mandatory The RemoteHost (agent).Format (string without double qoutes/IpAddress).
- * OID option Give multiple no. of Object Identifiers with value.
- * value object-instance value .
