hi,
Various 6300M might have various ports capability, look for your specific model and go as high as you can.
and look in the manuals Transceiver Guide. Follow best practices.
Look for new model S0E91A,, supporting "Up to 400 Gbps stacking bandwidth"
(HPE Aruba CX 6300 new addition S0E91A & S0X44A! | Wired Intelligent Edge (arubanetworks.com))
be aware:
"50G capability is for use with 50G DACs for both interconnect and VSF stacking. 50G transceivers and DACs are not supported on S0E91A and S0X44A switch models, which requires QSFP to SFP56 DAC cable for VSF stacking with other CX 6300 switch models. VSF stacking not supported on 1G ports"
happy stacking
