- /**
- * This is an example program to explain how to write an application to send a
- * v2c Trap message using com.adventnet.snmp.snmp2 package of AdventNetSNMP2 api.
- * The user could run this application by giving any one of the following usage.
- *
- * java snmpv2ctrap [options] -m mibfile hostname timeTicks snmpTrapOID-value [OID value] ...
- *
- * java snmpv2ctrap [-d] [-c community] [-p port] -m MIB_files host TimeTicksvalue OIDvalue [OID value] ...
- * e.g.
- * java snmpv2ctrap -m ../../../mibs/RFC1213-MIB 10.3.2.120 16352 coldStartTrap ifIndex.2 2
- *
- * 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 .
- *
- * If 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] - Debug output. By default off.
- * [-c] <community> - community String. By default "public".
- * [-p] <port> - remote port no. By default 162.
- * -m <MIBfile> - MIB files.Mandatory.To load multiple mibs give within double quotes files seperated by a blank space.
- * <host> Mandatory - The RemoteHost (agent).Format (string without double qoutes/IpAddress).
- * <timeticks> Mandatory - the value of object sysUpTime when the event occurred
- * <OID-value> Mandatory - Object Identifier
- * <OID> - Give multiple no. of Object Identifiers with value.
- * <value> - object-instance value
