Meraki MS130-48X Connectivity issues

[BKP09]

Hello everyone, 

We recently deployed a new site with a standalone FortiGate firewall configured with an LACP aggregate uplink to a Meraki MS130 switch. Although the physical links appear to be up and active, we are experiencing significant connectivity issues. Most VLANs are unable to reach their respective gateways, and basic connectivity, such as ICMP (ping), is failing for the majority of them. 

The configuration we used is used by many sites with the same deployment design with MS130 but 16.9 version.

Has anyone faced any similar issues? is downgrading/upgrading an option? 

Version 17.2.1

It appears to be a version bug (I've seen similar reports), try downgrading to see if it will resolve the issue.

Thank you for you prompt response.
Do you have in mind a specific version? 17.1.2? or 16.9.X?

[alemabrahao]

You are having problems with 17.1.2, right? Then I think you should try version 16.9

[BKP09]

Thank you. 
The devices came with the 17.2.1 version preinstalled and there is no available downgrade path on the available versions, only 17.5.X does the downgrade require TAC case support ticket?

[alemabrahao]

I suggest you open a support case.

Similar issue with MS-130 24X on 17.2.1, no roll back option. Case opened.
