Catalyst 9400 Bandwidth Numbers

[MikeO5422]

Hi,

I was looking at the datasheets for the 9400s. Taking the example of a 9410, I see that all supervisors currently support 80Gbps per slot. I was confused as to if that rating was unidirectional or bidirectional.

Hi @MikeO5422 ,

Maybe this link can give you some help:

As per my understand it was Bidirection 80GB with sup1

here is the archtecture for reference ?:

Thank you, I will read through it. I was speculating that the numbers were 80Gbps for TX plus 80Gbps for RX (160Gbps total) based on their over subscription ratios and 10G/40G port configurations on the supervisors. 

*edit* - I need to be more clear with my usage of unidirectional and bidirectional so I edited out those terms in my response. I may be using them wrong or in a confusing way.

It is 80Gbps in each direction for the 9410 with any of the Supervisors.
