![]() This means that you can centralize your network capture devices. RSPAN extends SPAN by enabling monitoring of multiple switches across your network and allowing the analyzer port to be defined on a remote switch. Remote Switch Port Analyzer (RSPAN) is an extension of SPAN. ![]() A network analyzer connected to the monitoring port processes the data packets for diagnosing, debugging, and performance monitoring. This is commonly used for network appliances that require monitoring of network traffic, such as an intrusion-detection system. Port mirroring is used on a network device to send a copy of network packets seen on a single device port, multiple device ports, or an entire Virtual Local Area Network (VLAN) to a network monitoring connection on another port on the device. The network analyzer can be a Cisco SwitchProbe device or other Remote Monitoring (RMON) probe. Switch Port Analyzer (SPAN), or sometimes called port mirroring or port monitoring, chooses network traffic for analysis by a network analyzer. This article provides instructions on how you can configure RSPAN on your switches.
