I have one cisco WS-C4506 with bootflash:cat4000-i5k91s-mz.122-20.EWA4.bin configured for multiple VLAN's.
Users are connected for VLAN-10, and I have 3 Mbps internet bandwidth for the users, I am getting MRTG from ISP that my all lines are chowcked, ppl are downloding too much, hence pls. suggest any commands to enable on Cisco 4500, so i can find the culprit to restrict the user from downloding or streeming.,
You can configure Netflow on the device & use the "show ip cache flow" command to see which flow is downloading or uploading beyond a limit. Kindly find the link below which describes Netflow on Cisco 4500 device.
Yes Netflow on the Cat 4k with older supervisor requires the add-on card or Supervisor upgrade. Netflow is definitely the best tool for the job though
Do you control the upstream router (towards the ISP?) if you can do a flow export from there, that would be ideal. You might be able to get your provider to send exports to you for analysis if they control it.
You'll need to fire up an analyzer like ntop (open-source) or SolarWinds NTA (licensed but free trial or realtime analyzer available)
