80 APPENDIX B: NETWORK CONFIGURATION EXAMPLES

Simple Network Configuration

Examples

The following illustrations show some simple examples of how the Switch

4200 family and 4900 family can be used in y our network.

Segmentation Switch

Example

The example in Figure 21 shows how a 10/100 Switch such as the Switch

4200 stack can segment a network of shared 10 Mbps a nd 100 Mbps

connections. There is a 10/100 shared segment on each floor, and these

segments are connected to the Switch which is positioned in the

basement.
