This task is implemented by two lines of commands. Set up SPAN on IOS switchesįor these switch models, you need to get to the device’s operating system and issue a command in order to specify the SPAN port and the port to monitor.

You can use any network analysis software to process the packets that are sent to your device. The port mirroring setup will not store or analyze the traffic. These steps will just divert copies of traffic packets to the port that to which you connect your device. Related post: Port Mirroring Guide Set up SPAN on the switchĬisco recommends different methods for setting up port mirroring with SPAN according to the version of the Catalyst switch. The term “destination” in SPAN refers to the port that the packet sniffer is connected to it doesn’t mean the destination of monitored traffic. Here, the “source” is any port, not the origin of traffic. The terms “ source” and “ destination,” which are commonly used in networking have slightly different meanings within SPAN. A little terminology needs to be explained. You can set SPAN to monitor a VLAN port and you can also specify that it should monitor all VLAN traffic. The RSPAN option isn’t available on all Catalyst switches - Express 500 / 520, 5500/5000, 3500 XL, 2940, 2948G-元, and 2900XL switches don’t have the RSPAN feature. A variation on SPAN, called RSPAN (Remote Switch Port Analyzer) enables you to monitor traffic between switches. It is also possible to identify the direction of traffic to that port. The SPAN system is able to monitor a single port or many ports. With SPAN, all traffic passing through the port is replicated and sent to the sniffer port. Without SPAN, the sniffer would only pick up broadcast messages because the switch closes a circuit between two communicating devices, locking out the sniffer attached to a different port. The SPAN facility lets you connect a packet sniffer to a switch. Note: The setup process is different for each model. SPAN is the Switched Port Analyzer that is available on some Cisco Catalyst Switches.
