The discussion of SPAN includes the following topics:

- How to use VSPAN to monitor traffic in a VLAN
- How to use RSPAN to monitor traffic across multiple switches
- How to use the Network Analysis Module (NAM) and Switched Fabric Module (SFM) to improve switch monitoring and performance

Topics discussed in security for multilayered switched networks include the following:

- Security concepts
- Security and remote device management
- Technologies available for controlling user traffic
