Application Layer PT Server Activity

Application Layer – Server Activity Overview

It is important to know the basic functions of the various networking programs that operate at the Application Layer. The average person uses these Application Layer programs on a daily basis without ever wondering about how they fit into the layered networking models of the OSI and TCP/IP models. These Application Layer services continue to be important as we learn about how they correspond to source and destination port numbers within the Transport Layer header. 

Cisco Packet Tracer Activity

Set up the following services on the servers in Packet Tracer: DHCP, DNS, HTTP (Web), FTP, and Mail. If you configure everything correctly you should be able to: receive ip addressing to the DHCP clients from the DHCP server, resolve domain name requests from the DNS server, successfully receive requested web pages from the web server, upload and download files after logging into the FTP server, and send and receive email to and from the mail server. Here is a rough outline of the steps involved:

  1. Physically connect all of the devices with appropriate cables,
  2. Configure IP addressing on all of the networking devices (follow the device labels),
  3. Configure the server services on the devices as listed (dhcp, dns, mail, web, ftp),
  4. Verify that all of the configured services work by testing from the client computers,
  5. Note: In this Cisco PT activity the services and testing do not extend beyond the LAN i.e. router.
