Understanding
ICMP and SNMP polling
The
IP Availability Manager
and IP Performance Manager
uses
the Internet Control Message Protocol (ICMP) and Simple Network Management
Protocol (SNMP) polling to monitor the IP network. The results of
this polling are then compared to threshold values that define acceptable
and unacceptable levels of connectivity or performance. The thresholds,
in conjunction with traps, are used to diagnose the failed or degraded
objects that interrupt network connectivity or adversely affect network
performance.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
through the Polling and Thresholds Console.This discussion focuses on the polling-related
settings. Threshold related settings are described in the .
