Hello all,
i've been working on a few Meraki devices and I've seen some failover events come through. I would like to understand the logs better.
Security appliance Client Event type Details

Sep 29 15:31:01 | MX001 | VRRP transition | if_up: 0, old_if_up: 1, mode: detect

Sep 29 15:26:05 | MX001 | VRRP transition | if_up: 1, old_if_up: 0, mode: detect

My Objective: Identify when the primary failed and switched to being a Backup.
Could someone help me understand the status codes in the Details section. I have read through the Routed HA Failover Behavior. But I do not understand the Elector state .
Is it saying Elector State- Master = Device is currently Master
and Elector State - Backup = Device lost connectivity and is now Backup ( Spare becomes Master)?
Could someone please clarify the same for me. Would highly appreciate it!
Thanks,
Craig.
Solved! Go to Solution.
Exactly:first, it had a priority of 255 and was acting as VRRP master. Then it looks like its uplink failed, therefore it transitioned to Prio 75 and went into Backup state.
Does the fine manual help?https://documentation.meraki.com/MX/Networks_and_Routing/Routed_HA_Failover_Behavior#VRRP_Mechanics_...
@CptnCrnch that indeed did help and i appreciate you referencing the link too.
However, what I am not understanding is the section Elector State - Master / Elector state - Backup
As per my reading of the link and understanding - 255 for Primary is Master and anything below that is Backup
As per my logs at Sep 29 15:26:05 MX001 - transitioned into Master as Prio is 255 and then at Sep 29 15:31:01 MX001 transitioned into Backup as Prio is 75.
Can you confirm that my understanding of this is correct?
