Switch system bandwidth

[Anwar Safian]

Hi Expert

In Catalyst 9400 datasheet, there is statement mention " up to 9 Tbps of system bandwidth".

My inquiry is 

1) What is system bandwidth? 

2) How we calculate to get 9 Tbps in Catalyst 9400

That is the Whole Performance of the chasis (that applicable for 10 slot chasis)

up to 80GB per slot around

more information can be find here :

Hi Balaji

Thanks for your reply.

I am still confuse how 80Gbps per slot relate to 9Tbps.

Is there any calculation that can show how 9Tbps come from?
