I believe I am having a similar problem as others have had with SwitchOS. I have a CRS326Q-24S+2Q+ and a CRS328-24P-4S+RM. I'm connecting them with a QSFP+ to SFP+ AOC breakout cable, but SwitchOS does not allow me to set the QSFP+ port on the CRS326Q-24S+2Q+ to 10G for each port. I can get this to work in RouterOS, but I don't see 10G as an option in SwitchOS if I turn Auto Negotiation off. According to compatibility, 10G MUST be turned on instead of auto negotiate. Any help would be greatly appreciated.
