RB260gs packet buffer size

Hello, I would like to know what is the packet buffer size of the RouterBoard 260GS ? In the spec, I see that there is a 128Kb of storage and 0Kb Ram…

And does this amount is for the whole system or for each port ?

Thank you

P.S. I’m not sure where to post this topic, so I posted in SwOS and Hardware. I will delete the duplicate when answer will come.

RB260GS has Atheros AR8327 switch chip and SFP slot
1MBit Packet Buffer (128kB) total

So it’s 128Kb share with all ports.

Thank you
