Meraki Switch Compatibility

[Naresh_Pattu]

Hi,

Customer is currently have a Meraki full stack network, however they are planning to connect some servers and storage with the existing network through catalyst 3750 switch (temporarily). 

I just want to know, will there be any impact in the network if we connect this old (non-Meraki) switch.

It should be fine.  It would be safest to set the Cisco 3750 to use MST spanning tree.  You configure this using this command:

spanning-tree mode mst

Pretty much what Philip said.
Try to avoid PVST/RPVST and keep with MST which plays best Meraki since you don't have any PVST simulation errors.
