- Connect the servers to one switch using a straight-through cable.
- Connect the client computers to the other switch using a straight-through cable.
- Interconnect the two switches using a crossover cable.
9. Verify connectivity
- Ping (ICMP)
- From a client computer use the Desktop Command prompt to ping the other client computers and the servers.
- Example: From the Dynamic 1 client, C> ping 172.16.0.20
- The first one or two pings may fail, but you should receive a reply on the later pings. This is due to the ping timing out while the ARP process takes place.
- Web Browser (HTTP)
- On the client computers use the Desktop Web Browser, enter the URLs of the Web Servers www.cabrillo.edu and www.internal.com.
- You should see the web pages that you created on these servers.
- Email (SMTP)
- From client computer (Dynamic 1), compose an email (from Desktop tab) to another client computer (Static). To: user3@mail.mapua.edu
- Upon sending the email, check if email was received by Static PC by clicking the email icon (Desktop tab), and clicking the Receive button after.
Please approach your instructor to verify connectivity of devices
