Meraki MS225 Switch Stack and MS120 Switches with Aggr. Interfaces not working

Hey!

 

I'm trying to create a LAG between the SFP ports on these switches but I'm running into issues with LACP.  After creating the Aggr Interface on the MS120 side using ports 25/26 and using one of the ports from 49-52 amongst my 3 stack members, LACP shuts down one of the ports in the Aggr.  I need to understand why.  I also don't get 10Gbps on these ports with 10G sfps(no errors), the port speed is auto negotiated to 1 Gbps, with no other option to enforce the 10G bandwidth.  I also don't see a way to choose between LACP/PAGP(Cisco proprietary) or to manually enforce LACP via configuring both switches to be in an "active"/"active" state.  Any help is appreciated.

MS120 only has 1Gbps uplinks. 225 can do 10Gbps uplinks. What transceiver are you using on the MS225 side?

OK, here you go

SFP moduleSyrotech - 10GBASE-SR: 10.3 Gbps (Part GOXP-8596-02, Serial: SY1902-OLC00139 )

Do you Aggr setup on the port(s) you are using on the MS225 as well?
