Traps are forwarded as notification originators by calling the forwardAsNotificationOriginator() method.
When translating from SNMPv1 to SNMPv2, the SNMPv2 varbinds are the same as the SNMPv1 varbinds.
When translating from SNMPv2 to SNMPv1, the SNMPv1 agent-addr parameter is determined as follow:
If the notification is sent over IP, the SNMPv1 agent-addr parameter is set to the IP address of the SNMP entity in which the notification originator resides.
If the notification is sent over some other transport protocol, the SNMPv1 agent-addr parameter is set to 0.0.0.0.
