High Receive Utilization on VLAN (data)

We use Solarwinds Network Monitoring and noticed that one of our core switches in one building always has a high receive utilization on the main data vlan (20). The switch is a 4503. Is there a way to find out what client or switch is causing this high utilitzation spike? It happens only during working hours. It's always around 75 - 100% throughout the day.

Hi Banseryan,

 

You should be able to configure netflow on that switch, this will tell you who the offending senders/receivers are. 

I have enclosed a link to the relevant config guide (though this is dependant on having the correct cards in the switch)

Very best wishes
