Hi,
I'm searching for a way to know online (or historical) if I have an issue because port oversubscription.
Can I see the current (or historical) port group entiere bandwith?
Or maybe I should manual calculate each of the shared port utilization?
Thanks,
Amir

in device manager right click on the module and select "Check Oversubscription", then select Monitor and pick appropriate port group you want to monitor.

Thanks,
But can I get this information from a command line?
I want to capture current status when I'm suspecting a problem using a script, or get historical data of this
Thanks

For CLI you can use the following:
Switch# show port-resources module X
ex:
switch# show port-resources module 8
Module 8
Available dedicated buffers are 5400

You can also use the command “switch# show interface counters brief”
to determine the traffic at a 5 minute interval and determine the available
bandwidth between the oversubscribed ports.

Is there a command to see the actual usage of a port group ?
