Using Named Source-Port Filters

A company wants to manage traffic to the Internet and its accounting server
on a 26-port switch. Their network is pictured in Figure 8-4. Switch port 1
connects to a router that provides connectivity to a WAN and the Internet.
Switch port 7 connects to the accounting server. Two workstations in
accounting are connected to switch ports 10 and 11.
Network Design
1. Accounting Workstations may only send traffic to the Accounting Server.
2. No Internet traffic may be sent to the Accounting Server or Workstations.
3 All other switch ports may only send traffic to Port 1.
