Note:
To achieve shorter delays before failover, use lower Monitor Interval and
Missed Packets values. This may be necessary for IP addresses on
machines, such as a web server or order processing database, which
must remain available and responsive at all times. Lower values should
be used where redundant interfaces and high-speed, reliable network
links are available to prevent the false detection of failure. If the hardware
does not support reliable communications, lower values can lead to
premature failover. To achieve longer delays before failover, choose
higher values. This may be necessary for IP addresses on slower
networks or on a server that is not transaction critical. For example,
failover would not be necessary in the case of a server restart.
12. If you are monitoring multiple IP addresses, highlight the source name and specify
the Failover Trigger.
● All Monitored IP Addresses Fail—Failover begins when all monitored IP
addresses fail. If there are multiple, redundant paths to a server, losing one
probably means an isolated network problem and you should wait for all IP
