Failover latency

L0 Member


I have one question and I hope somebody will help me.

Does PaloAlto has a recommendation for failover link latency. For example I have firewall cluster and this cluster is done across wide area.  What max latency should be used for properly functionality between cluster members.  For example cisco says that failover link latency should be less than 10ms and no more than 250ms.

Hello Aaputis,

As per my knowledge, there is no document available which will provide you the exact latency during a failover, rather with optimal time best practice.

Few related links:

Thanks for answer, am I thinking if those parameters in documentation will help to optimize, if I want deploy Paloalto cluster in wide area, where long distance is between cluster members.
