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.

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.
The .pka file is not for the topology being shown and discussed.
You show D2 F0/24 going to S3 G/01 but then show that interface already connected to R2 G0/2 making the D2 F0/24 an impossible connection.
Also, how did you determine the connections for interfaces without IP addresses? They don’t appear in with any of the IOS commands. In my copy of the PKT “Show port Labels when Mouse Over” is disabled,making that option not possible to use.
There’s a mistake in the adressing scheme.
D2 has int. F0/24 with address 10.3.0.1 and subnet mask 255.255.255.0 but connects to S2 (not S3) on G0/1.
Please review a typo on: D2 > F 0/24 > 10.3.0.1 > 255.255.255.0 > “S2” > G 0/1
Yall wrote “S3” but S3 is not connected to D2 on that topology.
For D2, F0/24, the connecting device should be S2?
D2 | F0/24 Z 10.3.0.1 | 255.255.255.0 | S2 | G0/1
D2 F0/24 connecting device is S2, not S3. The only thing connected to S3 is centralserver and R2
Hi,
Thank you so much for sharing this! However, I think there is a wee mistake for which device is connected to D2 from F0/24. It should be S2 and not S3 from the G0/1 connecting interface.
The 6th last line:
F0/24 | 10.3.0.1 | 255.255.255.0 | S3 | G0/1
The connecting device needs to be S2 | G0/1, right?
Because S3 isn’t connected to D2, but to S2.
The last line is incorrect:
Because D2 isn’t connected to S3, but to S2.
typo on d2. d2 is not connected to s3, should be s2
