Can I use Twinax breakout cables as meraki uplinks?

[JackShep]

If I aggregate 4 ports on an MS425 stack, can I connect the (4) SFP adapters from a cable like this

(Cable Matters 40GBASE-CR4 Passive QSFP+ to 4X SFP+ DAC Twinax Breakout Cable (QSFP to SFP Cable) - 1m, 3.3ft https://a.co/d/3RDXytI)

to the agg ports and then connect the other QSFP male end into a qspf+ port on an MS355-48X2 and us that as uplink?

This is our official list of supported transceivers https://documentation.meraki.com/General_Administration/Cross-Platform_Content/SFP_and_Stacking_Acce...

Anything outside of this is may or may not work correctly. In general I've not seen any breakout style cable work in any Meraki device.

No.

As @PhilipDAth said, those will not work.  The switch needs to have four virtual interfaces for the port and in the case of Meraki switches, they do not.

@Ryan_Miles it would be a useful feature, would you be able to find out if it is a hardware or firmware restriction?
