- /**
- * Send SNMP trap based on command line arguments. Loads MIBs
- * as specified, and converts to/from names for loaded MIB data.
- * Since variable types are not input, MIBs have to be loaded for
- * any variables being used in trap PDU.
- *
- * This is an example program to explain how to write an application to send a
- * Trap message using com.adventnet.snmp.beans package of AdventNetSNMP2 api.
- * The user could run this application by giving any one of the following usage.
- *
- * Note: Refer README file
- *
- * 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 .
- *
- * [-d] - Debug output. By default off.
- * [-c] <community> - community String. By default "public".
- * [-p] <port> - remote port no. By default 161.
- * [-m] <mibs> - The mibs to be loaded.
- * [-v] <version> - version(v2 / v3). By default v2.
- * [-e] <engineID> - EngineID for this entity.
- * [-u] <username> - The v3 principal/userName
- * [-a] <autProtocol> - The authProtocol(MD5/SHA). Mandatory if authPassword is specified
- * [-w] <authPassword> - The authentication password.
- * [-s] <privPassword> - The privacy protocol password. Must be accompanied with auth password and authProtocol fields.
- * [-i] <contextName> - Context Name.
- * <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> Mandatory - Give multiple no. of Object Identifiers.
