The Cisco 1800 series integrated services routers (fixed) support eight Fast Ethernet ports on which you can configure VLANs. But after the configuration of SPAN on switch, switch starts making copies of frames passing through its ports and send them to network analyzer. On most Cisco IOS switches, the configuration for SPAN involves the following steps: Create a SPAN session. A switch stack basically works like a single switch with a single configuration, much like a chassis switch with multiple blades. Cisco calls their port analyzer/monitor feature SPAN (Switched Port ANalyzer).The document Configuring the Catalyst Switched Port Analyzer (SPAN) Feature describes which models support SPAN, its configuration, and performance impact. About Cisco SPAN switches. A Switched Port Analyzer (SPAN) session is an association of a destination interface with a set of source interfaces. Usually, this will be some kind of dedicated system set up to monitor the traffic on that switch. So, I have built a tool that allows users to configure SPAN sessions on a Cisco switch.
