Getting this type info from the switch is not easy. If you have a management software like Solarwinds or PRTG, you can monitor each vlans and see the bandwidth consumption.

I have solarwinds but in the same time its trunk port with more than 200 Vlan's , Do you know if solarwinds can tell which Vlan causing this storm.

On the 3750E, enter the command:
sh controllers utilization
NOTE: The output is in "real time".

Hi,
It is not easy to get details from the switch itself. Better to you Netflow and get top talker and real-time analysis.
