Chapter 1 Configuring Interfaces and Circuits

Configuring the Switched Port Analyzer Feature

Figure 1-3shows an example of SPAN connectivity with a protocol analyzer connected to port 2/13 on a CSS. In this example, the CSS copies all packets received or transmitted on Fast Ethernet (FE) port 2/4 (SSPAN port) to FE port 2/13 (DSPAN port). The analyzer connected to DSPAN port 2/13 receives all network traffic that the SSPAN port receives or transmits.
