Hardware question on RB5009

Fri Nov 12, 2021 3:27 pm

Hi there, i was wondering how the swtich on the RB5009 is arranged.

According to Mikrotik all ports are connected on te switch chip, thats:
7 times a 1Gb connection
1 times a 2.5Gb connection
1 times a 10Gb sfp+ connection
and there is a 10Gb connection to the CPU

But when i read about the used switch chip this seems impossible:
High performance, non-blocking, 11-port Ethernet Switch integrating
- Eight 10/100/1000Mbps PHYs with Advanced Virtual Cable Tester
(VCT) diagnostic features
- Two 10Gbps XAUI/RXAUI Interfaces
• 2.5Gbps/1Gbps also supported
- One RGMII/MII/RMII interface


How is there a 10Gb connection with the cpu, a 10Gb sfp+ port and a 2.5Gb ethernet possible if not using one of the switch ports of the cpu itself?

Documentation on Switch:

I hope my question is clear

RB5009 block diagram specifies switch chip Marvell 88E6393X which features 8 port GE PHY (i.e. eight 1Gbps ports) and 3x XG SerDes (i.e. three 10Gbps ports).
