Packet Tracer – Documenting the Network (Instructor Version)

Instructor Note: Red font color or Gray highlights indicate text that appears in the instructor copy only.

Topology

Background

In this activity, your job is to document the addressing scheme and connections used in the Central portion of the network. You must use a variety of commands to gather the required information.

Note: The user EXEC password is cisco. The privileged EXEC password is class.

Requirements

• Access the command line of the various devices in Central.
• Use commands to gather the information required in the Addressing Scheme and Device Connection Documentation table.
• If you do not remember the necessary commands, you can use the IOS built-in help system.
• If you still need additional hints, refer to the Hints page. In Packet Tracer, click the right arrow (>) on the bottom right side of the instruction window. If you have a printed version of the instructions, the Hints page is the last page.

Addressing Scheme and Device Connection Documentation

Hints

To gather IP Address and Subnet Mask:

• Click on the Router / Switchs in Central
• Click on the CLI tab
• Change to the privilege EXEC mode by typing enable.

Use the following commands to gather the information you need to document the network (include IP Address or Subnet Mask):

show ip interface brief
show interfaces
show running-config
ipconfig

An example for R2.

R2#show running-config 

<output omitted>

interface GigabitEthernet0/0
 ip address 10.255.255.245 255.255.255.252
 ip ospf priority 255
 duplex auto
 speed auto
!
interface GigabitEthernet0/1
 ip address 10.255.255.249 255.255.255.252
 ip ospf priority 255
 duplex auto
 speed auto
!
interface GigabitEthernet0/2
 ip address 10.10.10.1 255.255.255.0
 duplex auto
 speed auto

<output omitted>

Do the same for devices S1 S2 S3 D1 D2

To gather Device Name and Interface: go to Options > Preferences > Interface Tab > check Show Port Labels When Mouse Over in Logical Workspace.

Mouse over the green triangle of the link. The interface port name will be shown.

Another way:
On Router/Switch, access each interface port in the table in turn, deactivate it with the shutdown command.
Refer back to the network diagram to determine the location of the deactivate interface (indicated by the red triangle).
Once the deactivated interface has been identified, use Place Note (N) tool to note the deactivated interfaces.

(You can also redraw the Central portion on paper, then use a pen to note the names of the deactivated interfaces)
Re-activate the interface by executing the command no shutdown

R2(config)#interface g0/0
R2(config-if)#shutdown    ~~~~~> Note g0/0 on topology
R2(config-if)#no shutdown 

R2(config-if)#interface g0/1
R2(config-if)#shutdown     ~~~~~> Note g0/1 on topology
R2(config-if)#no shutdown 

R2(config-if)#interface g0/2
R2(config-if)#shutdown     ~~~~~> Note g0/2 on topology
R2(config-if)#no shutdown 

Do the same for devices S1 S2 S3 D1 D2

Once you have completed the above steps, you can complete the Addressing Scheme and Device Connection Documentation table.
