HA & Failover - What causes it?

Louis-M

In HA (Hot standby mode), what causes the UTM to switch and can it be controlled eg only failover on certain ports?

For instance, if I have E0 - E7 physical interfaces hooked up on master & slave, will pulling any interface on the master result in a failover?

If E8 is live on the master, but E8 on the slave doesn't have a connection, will pulling E8 on the master result in a failover?

    Hi Louis-M,

    as far as know all physical ports are monitored by default and every port must have the same state (connected/disconnected) on master and slave to have a 'good' clusterstate. You maybe can exclude certain interfaces from being monitored in the hardware setting of the phys. interface - at least there is a chekbox 'HA monitored - but I didn't try that maself.

    I think in your example the utm with the longer uptime will survive - I think if there is an equal number of good interfaces the next criteria is the uptime that decides whats happening.

    Best regards

    Manfred

    Thank you. That answered my question. Never went into the hardware tab so I can see that is now where it is done.
