MX Failover, what are the LAN scenarios?

[MSakr]

Hi All

What happens if the LAN side fails in a HA scenario on the MXes? I couldn't find anything here or on the forum

https://documentation.meraki.com/MX/Networks_and_Routing/Routed_HA_Failover_Behavior

Will the one with the connected LAN become primary? suppose lan cables unplugged or damaged

Also when we click on the swap the primary and spare in a HA, what mainly happens here?

Thanks

Swap primary/spare is based on the vrrp prio and swaps the dashboard view old spare is then primary
