Understanding ICMP and SNMP polling and thresholds

The IP Availability Manager and the IP Performance Manager uses Internet Control Message Protocol (ICMP) and Simple Network Management Protocol (SNMP) polling to monitor the IP network. The monitoring of the network is controlled by ICMP and SNMP polling-related and threshold-related settings that are created for the IP Availability Manager and the IP Performance Manager through the Polling and Thresholds Console.

This discussion focuses on the threshold-related settings. Polling-related settings are described in the IP Manager User Guide.
