- * This is an example program for receiving SNMP Inform Requests using the
- * com.adventnet.snmp.snmp2 package of AdventNetSNMP2 api.
- * The user could run this application by giving any one of the following usage.
- *
- * java snmpv3informreqd [options]
- *
- * java snmpv3informreqd [-d] <-p port> <-u user> <-e engineId>
- * [-a authProtocol] [-w auth_password] [-s priv_password]
- * e.g.
- * java snmpv3informreqd -p 2000 -u inform_test -e 1234
- *
- * Mandatory Options:
- * <-p port> - remote port no.
- * <-u user> - user name
- * <-e engineId> - Engine Id
- *
- * Optional Options:
- * [-d] - Debug output. By default off.
- * [-a authProtocol] - Authentication protocol used.
- * [-w auth_password] - Authentication password used.
- * [-s priv_password] - Priv protocol used.
- *
- * Note:
- * 1. If neither of -a, -w, -s are used, then the security level is NO_AUTH,
- * NO_PRIV,
- * 2. If -a, -w are used, then the security level is AUTH, NO_PRIV,
- * 3. If -a, -w and -s are used, then the security level is AUTH, PRIV,
