Technical Tip: HA failover failure cause by link failure

For example, HA failover has to override disabled under the HA setting, monitored interfaces are port1 and port2 as shown below:

config system ha

    set override disable

    set monitor port1 port2

end

HA failover can be triggered in the primary unit by using the command 'diagnose sys ha reset-uptime', failover has no response if there is a counter on the secondary's 'link_failure'.

The 'link_failure' counter can be checked using the command 'diagnose sys ha dump-by group' as shown below:

It is required to check the status of port1 and port2 under HA-monitored interfaces:

config system ha

    set monitor port1 port2 <-----

end

Note:

Each port failure results in 50 increments in the counter, for example, one monitored interface down is 50, and two monitored interfaces down will be 100.
