Trap and inform messages are SNMP notifications in which the SNMP agent notifies the SNMP manager about AE Services status changes and events. When a significant event, such as a service failure, occurs, the SNMP agent sends one of the following messages to the SNMP Manager:
Trap messages. These messages do not require confirmation from the receiver. All versions of SNMP support trap messages.
Inform messages. These messages require confirmation from the receiver. Only SNMP versions 2c and 3 support inform messages.
By default, AE Services send notifications as trap messages.
