Setting up a SPAN port

  • Updated 4 years ago
Network core switches typically have a feature called port mirroring or port monitoring, which copies network traffic from one port on the switch to a designated port called the monitoring port. LANGuardian uses this feature to capture network traffic data for analysis -- to monitor traffic with LANGuardian, you must connect it to a monitoring port.

This feature is given different names by different vendors. On Cisco switches, the monitoring port is called a SPAN port. See this YouTube video for details of how to set up a SPAN port and connect LANGuardian to it. You can find links to the document for other popular switches on our core switch documentation page.

If you need help configuring your switch to monitor network activity, contact our support team for free, no-obligation assistance.
