[c-nsp] C6509 Fabric Switch Capacity

[Alireza Soltanian]

Hi everybody

We have C6509-E with SUP720-3BXL. Based on what I understood from Cisco
Website, in this setup we can have 40Gbps in Fabric Switch between slots.
This Fabric Switch is divided into two 20Gbps channels.

Now in one our chassis we have this setup:

My questions are is What will happen if we exceed capacity(Egress or
Ingress) in Channel#0 of Slot#2? Will device use Capacity of Channel#1?

 

Thank you
