EM 12c, EM 13c : Incorrect IP address is Seen in the Header of the SNMP Trap Notification sent by the OMS (Doc ID 1614453.1)

Last updated on JUNE 28, 2018

Applies to:

Enterprise Manager Base Platform - Version 12.1.0.1.0 and later
Information in this document applies to any platform.

Symptoms

SNMP Trap notification has been configured in the EM Cloud Console to send SNMPv1 Traps to a third party SNMP Console.
SNMP Traps are being sent by the OMS to the 3rd party tool but the trap header shows the IP address as 127.0.0.1, as seen below:

 The Trap header should instead contain the actual hostname / IP address of the OMS machine, which is sending this Trap.
