Stacking MS225 with MS425

[JackN]

Currently we have multiple MS225's in a stack.

I'm now looking at introducing a MS425 as our server fleat is expanding and we need more 10gbe connectors 

can i add the 425 into the existing 225 stack via a 40gb qsfp? 

or is there a better method to introduce the the MS425 to the existing stack

Nope.

[JackN]

do you have any recommendations on how to connect them at as high as possible speed?

[NolanHerring]

The lowest common denominator here is the MS225, so you will be limited to the 10G uplinks it offers. So grab 4 of the 10G fiber modules and connect the switches together that way (aggregate the ports).

Pretty sure Meraki only allows you to stack switches that are the same model family as there are different stacking types.

Correct, Blake - except you CAN stack MS210 <-> MS225:   https://documentation.meraki.com/MS/Installation_Guides/MS225_Series_Installation_Guide#Bringing_you...
