- /**
- * This is an example program to explain how to write an application to do
- * the basic SNMP operation WALK using com.adventnet.snmp.snmp2 package of
- * AdventNetSNMP2 api.
- * The user could run this application by giving any one of the following usage.
- *
- * java snmpwalk [options] hostname oid
- *
- * v1 request:
- * java snmpwalk snmpwalk [-d] [-c community] [-p port] [-t timeout] [-r retries] host OID
- * e.g.
- * java snmpwalk -p 161 -c public adventnet .1.3.6.1
- *
- * v2c request:
- * java snmpwalk [-d] [-v version(v1,v2)] [-c community] [-p port] [-t timeout] [-r retries] host OID
- * e.g.
- * java snmpwalk -v v2 -p 161 -c public -m rfc1213-mib adventnet .1.3.6.1
- *
- * v3 request:
- * java snmpwalk [-d] [-v version(v1,v2,v3)] [-c community] [-p port] [-r retries] [-t timeout] [-u user] [-a auth_protocol] [-w auth_password] [-s priv_password] [-i context_id] host OID
- * e.g.
- * java snmpwalk -v v3 -u initial2 -w initial2Pass -a MD5 10.3.2.120 .1.3
- *
- * 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 .
- *
- * Options:
- * [-d] - Debug output. By default off.
- * [-c] <community> - community String. By default "public".
- * [-p] <port> - remote port no. By default 161.
- * [-t] <Timeout> - Timeout. By default 5000ms.
- * [-r] <Retries> - Retries. By default 0.
- * [-v] <version> - version(v1 / v2 / v3). By default v1.
- * [-u] <username> - The v3 principal/userName
- * [-a] <autProtocol> - The authProtocol(MD5/SHA). Mandatory if authPassword is specified
- * [-pp]<privProtocol> - The privProtocol(DES/AES-128/AES-192/AES-256/3DES).
- * [-w] <authPassword> - The authentication password.
- * [-s] <privPassword> - The privacy protocol password. Must be accompanied with auth password and authProtocol fields.
- * [-n] <contextName> - The context to be used for the v3 pdu.
- * [-i] <contextID> - The context to be used for the v3 pdu.
- * <host> Mandatory - The RemoteHost (agent).Format (string without double qoutes/IpAddress).
- * <OID> Mandatory - Give multiple no. of Object Identifiers.
