[c-nsp] C6509 Fabric Switch Capacity

[Chuck Church]

Like others said, the ports are mapped to ASICs and ASICs mapped to
channels.  Packets will drop.  A useful command is 'show platform hardware
capacity'.  That list peak utilizations along with when they happened.  At
least it should, older SXF didn't seem to have it working right, but I think
SXH should be ok.

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:

This output shows the Fabric Switch Utilization on each Slot:

9            0        20G           32           19

 

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

Alireza
