Hi, You could mirror the ports and use wireshark or some other network monitoring software to see what the traffic is. Page 711 [URL]
Hello everyone, Recently, I've just upgraded the latest firmware for the N3024 switch and watching the logs, ugh, everything still be okay as I thought. Then, some users reported that the network bandwidth sometimes slowly and I took a glance at the RMON Statistics via the web screen for making a graphical view. It looks like those ports Gi17 and Gi18 be taken rather high on the chosen field [Frames of 1024 to 1518 bytes] and the [Received Packets] [IMAGE][IMAGE] But for these fields such as [CRC & Align Errors] or [Oversized Packets] which be detected nothing. [IMAGE][IMAGE] Well, after a few checks, and I thought that those ports Gi17 & Gi18 did transfer data inside the local network with almost the file types are video extension. Maybe that the cause made the traffic became high on those ports and got the overall network slowing down. So, my question is how could I make a monitor or detect whether those ports really make the slow connection to the overall network or not? And I'd like to set a schedule and make a bandwidth's report for every specified time for all the ports. Be able to do it? For example, via the web screen or CLI settings, the scheduled report will automatically extract the bandwidth information of all or a few ports and send it to my email for every 5 minutes. Any help or advice are highly appreciated.  Thank you for your consideration, Dai M.
