A trap message processed for analysis purposes pertains to a device that has been discovered and therefore is already in the modeled topology. IP Performance Manager extracts the information from the trap message and updates the appropriate device attributes.


IP Performance Manager uses trap messages and the results obtained from periodic SNMP polling to detect network degradations that adversely affect network performance.

Chapter 3, MIBs Polled and SNMP Traps Processed, in the IP Manager Reference Guide, provides more information.
