I have Cisco 4500 switch port Gig22 show 88-99 % usage frequently port stats shows its a trunk port all vlan's are allowed i see a lot of Multicast and Broadcast traffic , My question is how can i tell which Vlan causing this huge traffic .
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.
It is not easy to get details from the switch itself. Better to you Netflow and get top talker and real-time analysis.
