Iperf3 and how to show actual bandwidth usage on a switch (Catalyst 2960 or 3750)

[Fab]

Hi everybody,

i use "iperf3" to see the speed of a switch (not only made by Cisco), putting 2 pc to both the side of the switch.

Is there a way to see also the total used bandwidth of a switch, in a specific time?

My goal is to see if a switch's bandwidth is satured or if there is a particular port which is using it a lot.

Many thanks.

Hi,

Not sure about specific time, but you get the average switch percentage utilization by using this command: 

sh controllers utilization

"sh controllers utilization" shows all zeroes!

This is the only command I found with this explanation:

"Switch Bandwidth Utilization"
