DHCP reservation in Meraki switch stack

[SrandaZitra]

Hi all, 

I work in a shop where it's usual to configure DHCP pools for switches. A colleague to mine struggles with configuring DHCP reservation for Meraki Switch Stack - is that practically possible? 

It's impossible to configure the same IP address reservation for multiple MAC addresses (stack members).

Is there any floating MAC address that's held only by active switch in the stack (of course DHCP request would need to be made from that MAC)?

Thanks in advance for your hints

Meraki switches work in a different way, where even when stacked, each switch must have its own IP. In other words, it is not possible to reserve the same IP for different switches.

Just a note, this statement is not true for the MS390 ande C9300 models, it does not follow this rule.

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!

The MS390 /C9300-M switches are Cisco Catalyst hardware that run the Cisco IOS-XE operating system.  For stable and RC firmware, the Meraki management software runs in a container on top.  For the beta it is part of IOS-XE.

The other switches are Meraki native with no IOS at all.

Adding to what @alemabrahao said, the management interfaces of each switch have their own Ip addresses, these normally remain constant, regardless of which member is the active stack master.

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.
