Aight, so my colleague that has the stack on his table (different site) has performed a test with following results:  DHCP reservation was created for active (stack-master) stack member Active stack member was forcibly disconnected from power New switch became active This resulted in lack of connectivity to Meraki cloud for 30 minutes After 30 minutes, the stack sent DHCP request resulting in having random dhcp-pool address, connectivity with Meraki cloud was renewed After re-connecting the switch disconnected in step #2 , that newly-booted switch acquired random dhcp-pool address which was changed to stack active switch' address soon after After reload of the whole stack, it took whopping 30 minutes for the stack to become visible in Meraki portal The switch that was originally active is active again and has DHCP-reservation address To me this seems that assigning the stack a static IP and calling it a day will be the best we can do.  ...

Thank you. I believe this is the closest to answering my question. I will conduct an experiment to figure it out empirically and get back to this topic.  ... View more

Thank you.  I should've write it in my original post - the switches in question are 9300. As @alemabrahao wrote, these are different in comparison to lower class switches - meaning 1 IP is assigned to the stack members.    I am curious about the details - ie. I have one IP address assigned to all the switches - how do I configure DHCP reservations? It's not clear to me due to answer of @alemabrahao that would need to be slightly more elaborated.  ...

Thank you for the response, would you be so kind and elaborate a bit more about MS390 and C9300 models - i.e. what is the difference in comparison to lower class switches, e.g. 210? Thanks!  ... View more

Sorry for being this insistive although the topic already got answered - I got the Z4 box handed out by my supervisor, he claims the limits (in my case 10) are there only for non-AutoVPN and he underpins that statement by stating that he has an older model - Z3 at home on 250Mbps (I have only 50Mbps) ISP uplink and for him and his Z3, with an older model, the 80+ AutoVPN tunnels are built flawlessly (all green in the portal). My question : would you be able to support me with some official detailed documentation as I fail to find one on my own? (I keep only finding very generic datasheets where I can't find this statement that it also includes Auto VPN). Thanks! ... View more

@ww The limit you have mentioned (10 max) - is that for non-meraki VPNs only or also for Meraki VPNs?  ... View more

Thank you, due to reasons that are out of scope of this reply, I never suspected this could be Z4 appliance limitation. This guide corroborates it, though: MX Sizing Guide & Principles - Cisco Meraki Documentation.  ... View more
