You enabled SNMP Notifications on Scan Engine (SSE) 5.2.11 and some warnings/errors are logged in the SSE log. You receive wrong SNMP traps for the these warnings/errors, i.e.:
The DDR feature was removed from SSE5.2.11 and the corresponding logging messages and SNMP traps were removed; this removal resulted in the unintentional discrepancy. This issue has been fixed for the logging feature (with hotfix 03) but SNMP was not fixed.
This issue is fixed with Scan Engine 5.2.13 or greater and Symantec Protection Engine 7.0.x.
Symantec Scan Engine 5.2.11 only. No other versions share the same issue.
