Objective:
Connect a workstation to LAN. Configure the network settings and troubleshoot as necessary. Use a
web browser to connect to router interface 152.20.71.237 and display the web interface. After the PC
is successfully connected to the network, the student should leave and the instructor will introduce
problems into the PC or network which must be resolved and documented in the space provided.
Include the following: symptoms, causes, details of tests done, detailed problem results (from layer 1
testing), detailed solutions.
Instructor notes: A list of potential problems and causes can be found in the instructor’s version of
the Semester 1 curriculum in the Preface, Chapter 0 under First Semester Finals.
Each student should be assigned a workstation number that will become the useable subnet # with
which they perform this assessment. Make sure each student has an appropriate assigned subnet
number before starting. Router configuration allows all workstations to maintain connectivity so
that you may test a class of up to 30 students simultaneously depending on your classroom
environment. Refer to the router configuration at the end of the instructor guidelines to set up the
router. Students must have the ability to alter the IP network settings on their workstations.
Students will be using a class C network 193.5.5.0 which is divided into subnets by borrowing 5 bits
from the network portion of the address. The subnet number assigned is the same usable subnet (1
st,
2
nd 3
rd etc.) as their workstation number. The proctor must initial each step. The following example
uses workstation / subnet 2. The default gateway for your host is 193.5.5.1.

Router Configuration Instructor Notes
Use the following configuration to set up the router for the skills test. Use a 2514 router with 2
Ethernet interfaces. ! Both interfaces e1 and e0 need to be connected to the hub. Router password is:
skills1. Router IOS should be at least version 11.2 but preferably version 12.
Students will be prompted for a password when accessing the router through the browser. This
indicates successful completion of the connectivity portion of the Sem 1 skills based assessment.
You may disable the password on the router if you wish for your students to see the web based
interface. (WARNING: this allows the students access to the router configuration) Therefore, you
may wish to wait until after testing is complete to disable the password and show the web-based
interface as a demo instead.
The following router configuration may be 1) keyed in manually at the router console, 2) entered via
the SETUP utility or 3) uploaded using the HyperTerminal Transfer / Send Text File option. Prior to
configuring the router, erase the existing startup configuration file.
Router> enable (Enter current enable password)
Router# erase start (Erases startup configuration file)
Router# reload (Don’t save the existing configuration and let the router reload
Refer to semester 2 labs for the procedures for loading the configuration file from a tftp server or
from HyperTerminal. After the router reboots, you may use the default setup mode or enter config
mode with the following command. Router# config t
