High Availability Latency / Bandwidth Requirements

[ET]

What are the Latency / Bandwidth Requirements for HA1 interfaces links between 2 HA members?

I saw a similar discussion here, but there is no actual answer in it

There is another related article: Next-Generation Firewall :HA Timers, but the timers here are mostly intervals rather than Latency.

https://docs.paloaltonetworks.com/ngfw/administration/high-availability/ha-timers

So I need to order a circuit (link) between 1 firewalls with Geo-cluster, and I need to know the requirements for it.

Thx

Hi @ET ,

There are no officially published latency or bandwidth requirements for HA1. The real requirement is simply that the circuit is stable, low-loss, and not congested. 

For real numbers, you'll have to capture the HA1 traffic between the peers or review interface counters/stats on an intermediate switch.
