How the ConfigChange event is enabled and processed shows the enabling and processing of the ConfigChange event.
Assuming that the ConfigChange trap capability is enabled, the IP Availability Manager responds as follows upon receiving a ciscoConfigManEvent or a sysConfigChangeTrap for a system that is already in the modeled topology:
Places the system on the Pending Devices list
Generates a ConfigChange trap for input to the Adapter Platform
During the next pending discovery, the IP Availability Manager will send SNMP polls to the system to rediscover the system and its components.
