Cisco 2960 LAG failed with Cisco Meraki MS350

[gruiz_cisco]

We have a Meraki MS350 switch stack, which has its firmware updated from version 12.28 to 14.24, since then the LAG connection between the stack and the Cisco 2960 switches is failing, could someone please tell us if there is any solution to this trouble.

i recommend you open a support ticket through dashboard or a phone call. they should be able to help you with this.

Things to check:
Are you using LACP passive or active mode on the Catalyst switches?
Are you NOT using fast timers (Meraki uses slow LACP timers just like the default on Catalyst switches)?
Is your Port channel configuration correct on Catalyst?

@gruiz_cisco 14.26 is current, although the release notes for 14.25 and 14.26 don't mention LACP, it might be worth a try.
