Source (SPAN) port: A port that is monitored.Egress Traffic: Traffic that leaves the switch.Ingress Traffic: Traffic that enters the switch.The Cisco method is called Switched Port Analyser also known as SPAN. Thankfully, monitoring network traffic on Cisco Catalyst switches is a straightforward process and does not require the presence of a hub. Of course switches work on an entirely different principle and do not replicate unicast packets out of every port on the switch, but keep them isolated unless it’s a broadcast or multicast. Those interested in hub fundamentals can read our Hubs & Repeaters article. Comments are welcomed below.Being able to monitor your network traffic is essential when it comes to troubleshooting problems, performing a security audit or even casually checking your network for suspicious traffic.īack in the old days whenever there was a need to monitor or capture network traffic, a hub would be introduced somewhere in the network link and, thanks to the hub’s inefficient design, it would copy all packets incoming from one port out to all the rest of the ports, making it very easy to monitor network traffic. I hope you find this article and its content helpful. Keep in mind that if your network has firewalls in place that you may need to add a pin-hole for that port:Ĭlick OK, and you will now be able to access the interfaces on that remote system! You must add port 2002 in the port number. Now click the "Add" button, and the following pop up will appear where you can add the host IP and port, etc. The Add New Interfaces dialogue will appear. In that box, select the "Manage Interfaces" button: The Wireshark Capture Options dialogue box will appear. Open Wireshark on your machine, select Capture> Options: The remote system(s) are now ready to be accessed by your local Wireshark application. Scroll down the services list until you find "Remote Packet Capture Protocol", right click on it and select "Start".
Enter "services.msc" into the Search box and hit Enter.With WinPcap installed on the remote system(s), you will need to start/configure WinPcap on those systems: Then you will also need the WinPcap applet installed on the remote Windows system or server. You will need Wireshark installed on a local system ofcourse. To do this we will use the remote capture feature built right into Wireshark! It is also better than running the entire application and remote desktop connecting to the systems. This is particularly handy for those who run Data Centers and other network applications. One of the cool things you can do with Wireshark is capture packets on remote servers or systems.
