In this section:

1. Campus Fabric Licensing
2. Handling SPX Links with Different Speeds
3. Campus Fabric Scalability
4. SPX Port Combinations
   Speeds on each end of an SPX link must match. The following tables provide valid SPX port combinations.
5. Control Bridge Considerations
6. Port Extender Considerations
7. Campus Fabric Topology Overview
