Asic to port allocation for X870 switch

[Rod_Robertson2]

I am trying to understand how the 96 ports of teh x870 are allocated to the asics.

We currently have 32 port switches ( x650 ) and basically I do not want to port over the standard configuration of the existing switch , if the first 24 ports are serviced by the first asic ..

Ok moving on .

Each port speed licence ( 17830 ) upgrades 6 QSFP ports to support 10-100 Gbit , max 4 licences per switch. So thats the first 24 ports covered ( 96 ports )

So can I assume ( not a good thing to do ) :

That the asic has multiple processors, one of those processor supports/controls 6 QSFP ports aka licence !!!

If not why do we licence 6 ports , whats the logic.

The main reason for all these question , is to install the switches , and connect the ports , so that in a few years , nobody can say we made the wrong design decisions.

That is means
"FrontPanelPort - PIQPort" == "1-34"

Interesting, so there is no benefit what so ever , of splitting port across the 96 10G preesentations.( 24 Port)

Im a little confused by the output 1-34 what does that actually mean ..

Hello Rod,

X870 platform is built on a one ASIC, X650 has 2 ASICs.
Ports are mapped as following:
