public class TrapPduv2
extends Pdu

This class represents the ASN SNMP v2c (and higher) Trap PDU object. This PDU is not supported in SNMPv1.

See SNMPv2-PDU;
The variable bindings list contains the following pairs of object names and values:

• sysUpTime.0 (SNMPv2-MIB)
• snmpTrapOID.0: part of the trap group in the SNMPv2 MIB (SNMPv2-MIB)
• If the OBJECTS clause is present in the corresponding invocation of the macro NOTIFICATION-TYPE, then each corresponding variable and its value are copied to the variable-bindings field.
• Additional variables may be included at the option of the agent.

For SNMPv3: The sender of a trap PDU acts as the authoritative engine.
