Unanswered Question

I saw this command posted a few days back and just now got around to trying it. Do you have any idea why I am not seeing any statistics on this switch?

Yes it means all your interfaces are running less than 1% utilization . And the stackring is transporting less than 1% of its rated 32gbps capacity .

Hello Glen,

from the output can we say that there is only one switch ?

if so the stack cable usage will be always 0

Hope to help

Glen, thanks for the response. What is the time metric involved here? Are these values in real time or 5 minute averages?

Yes from the output it is a single switch , if you have a stack it will show all ports within that stack . Yes the fabric will show 0 because there is no actual stackring with just a single switch. Won't swear to it but I think the counters are on the same 5 minute interface reading . Have never played around with the load interval to see if that affects the display or not .
