Method Detail

snmpReceivedTrap

void snmpReceivedTrap(SnmpTrapSession session,
                      InetAddress agent,
                      int port,
                      SnmpOctetString community,
                      SnmpPduPacket pdu)

This method is defined to handle SNMPv2 traps that are received by the session. The parameters allow teh handler to determine the host, port, and community string of the received PDU

Parameters:

session - The SNMP session

agent - The remote sender

port - The remote senders port

community - The community string

pdu - The SNMP pdu

snmpReceivedTrap

void snmpReceivedTrap(SnmpTrapSession session,
                      InetAddress agent,
                      int port,
                      SnmpOctetString community,
                      SnmpPduTrap pdu)

This method is define to handle SNMPv1 traps that are received by the session. The parameters allow the handler to determine the host, port, and community string of the received PDU.

Parameters:

session - The SNMP session

agent - The Trap sender

port - The port of the sender

community - The community string

pdu - The SNMP trap pdu

snmpTrapSessionError

void snmpTrapSessionError(SnmpTrapSession session,
                          int error,
                          Object ref)

This method is invoked if an error occurs in the trap session. The error code that represents the failure will be passed in the second parameter, 'error'. The error codes can be found in the class SnmpTrapSession class.

If a particular PDU is part of the error condition it will be passed in the third parameter, 'pdu'. The pdu will be of the type SnmpPduRequest or SnmpPduTrap object. The handler should use the "instanceof" operator to determine which type the object is. Also, the object may be null if the error condition is not associated with a particular PDU.

Parameters:

session - The SNMP Trap Session

error - The error condition value.

ref - The PDU reference, or potentially null. It may also be an exception.
