public class SnmpSession
extends com.ireasoning.protocol.snmp.SnmpBaseSession

This class implements a session for sending/receiving snmp message. By default, UDP is the underlying transport layer. But TCP transport layer is also supported.
The snmp requests are retried if time out. The default retry times is 3, but is configurable by using setRetries(int retries) method.

Note: Synchronous and asynchronous methods cannot be used together in one SnmpSession object. For example, for a SnmpSession object session, if you already use session.asyncSnmpGetRequest(...), another call to session.snmpGetRequest(...) may not work correctly.

Method Detail

setMibVersion

public void setMibVersion(String mibVersion)
Associates this SNMP session with the passed mibVersion. It's only necessary when you need to load multiple versions of one MIB.

Parameters:
mibVersion - If you have multiple versions of a MIB module, this parameter is used to distinguish different versions. It doesn't have to be the same as the actual version number, but it has to be unique among all the MIBs with the same module name.

getMibVersion

public String getMibVersion()
Returns the mib version associated with this session

loadMib

getPduData

public TransportData getPduData(SnmpPdu pdu)
                         throws SnmpEncodingException
Gets the PDU data in byte array format

Parameters:

Returns:
PDU data in byte array format
Throws:
SnmpEncodingException - raised if PDU's data is corrupted

asyncSend

public void asyncSend(SnmpPdu pdu)
               throws IOException
Used for asynchronous communication. Caller needs call addListener(Listener) first to register a listener object, then call this method to send out PDU, a separate thread (only one thread) will notify listener later about received PDU. It doesn't block after calling this method.

Parameters:
pdu - a pdu to be sent out.
Throws:
IOException - if socket is not valid.

send(SnmpPdu), snmpasyncget.java example

asyncSnmpGetRequest

public SnmpPdu asyncSnmpGetRequest(String oid)
                            throws IOException
Issues SNMP GET command asynchronously

Parameters:
oid - the SNMP OID to be sent to the agent. If it's a MIB node name (such as "sysUpTime", "ifAdminStatus.2"), it'll be converted to SnmpOID first if corresponding MIB file has been loaded by calling loadMib method.
Returns:
the request PDU object
Throws:
IllegalArgumentException - if passed MIB node name (such as "sysUpTime") cannot be resolved
IOException - if socket is not valid.
