The SNMPv3 standard requires each engine (trap sender) to have an ID. Each management platform (target application) honors the engine ID differently. Some management platforms, such as CA Server Automation, require that the actual hexadecimal engine ID is properly configured.
For CA Server Automation, the hexadecimal engine ID is built using a combination of the computer name and the string DCAMTrap as the seed. For example, if the computer name is COMP999, the seed of the engine ID is COMP999-DCAMTrap. CA Server Automation uses the seed in an algorithm to compute the engine ID. The computer name is used to ensure uniqueness. The hexadecimal value is written to an output file under the CA Server Automation installation directory. The name of the file is dem_snmp3_engine_id.dat. The file is created after you configure CA Server Automation to forward events to another management server.
