He is referring to HGSMII such as in GPON SFPs has been added to some switches since v7.3beta33

*) sfp - added 2.5Gbps rate for SFP+ and QSFP+ interfaces on 98DXxxxx and 98PX1012 switches (requires disabled auto-negotiation);

BINGO!

It is hoped that 2.5Gbps support can be added to the SFP + of rb5009.
It has been checked that his switching chip supports 2.5Gbps. I hope to support it.

My machine is rb5009 and the version number is 7.2 rc4.

I recently found a problem. After pppoe dialing at 10 Gigabit negotiation rate or 2.5g negotiation rate, connecting to the gigabit negotiation rate port, the external network Gigabit speed drops to 700.
Have you encountered the same problem?

My rb5009 encountered the same problem as you.I believe this is a bug.

Their same performance is that the address in the app is invisible.
