@BossnineYeah, we only experienced the 11.22 L3 issues on a switch stack.   I can't speak for the other firmware (11.29(.1)/11.30) as we haven't upgraded to any of those and don't intend to.    What version of firmware are you using? ... View more

We spent months on 11.22 trying to figure ot why "things" were dropping off the network. VM's, Physical Servers even the odd switch would just fall off the network. I think we spent about 3 months going round in circles logging calls with Meraki and various other vendors to figure out why.   We designed a really dirty workaround to help mitigate things dropping off the network with 11.22. It basically involved maintaining static ARP entries for everything on your network and having scripts ping critical devices.   I dont think that would help with TCN but it defintly helped us with 11.22 ARP/MAC Sync.   We are still on 11.22 but we have removed all L3 from all Stacked switches. This has stabilized us at the moment but we were looking to upgrade all our switches to 11.30 and move the L3 back but if there are still bugs in the code this kinda rules that move out.   ...

Hi @m3r4k1    We had to do the same with MS 11.22. We moved all L3 to other Non-Stacked Meraki switches. This "fixed" our problem but its not a long term solution. We were hoping that 11.30 would have allowed us to move the L3 back to the stacks but it doesnt sound like the L3 problem is actually fixed.   I am also cencerned at the speed of release of the firmware updates, I've mentioned bug tracking to account manager a few times but nothing has materialized.   ...
