How does IPM interact with the RTR feature of the Cisco IOS software?
IPM uses the Simple Network Management Protocol (SNMP) to configure RTR in the Cisco IOS software of a router or RSM to collect response time and availability statistics. The RTR samples response time and availability to targets (network devices, servers, and PCs) in the network. IPM then uses SNMP to collect response time information from RTR, and stores that information for presentation and analysis.
