The SNMP manager can either process a trap into an alert for the attention of the system user, it can send a request back to the device controller for more details, or it can just drop the message and do nothing about it. It shows various checkpoints where a trap can potentially be dropped and where and how to configure filters. SNMP traps contain valuable information about the objects in managed devices, so your network management system should be able to collect SNMP traps and enable you to analyze them. It also allows the SNMP manager to not have to store the detailed information of each alert within the OID. On the other hand, some serious events and conditions may not result in trap messages. The SNMP manager (monitoring server) in turn converts the trap into an alarm to notify the user.
