Brian ScheibeToday, we’ll continue part 2 of our blog series on Boson’s Cisco Network Simulator – NetSim 8.0 – in a classroom. This installment will cover steps 3 and 4.
Step 3: Create the Loading configuration files
You can now create a lab by using the lab document and topology files you have just created. Let’s now go over the steps to create loading configuration files. In our test lab we will create loading configurations for Router1 & Switch1 that allow them to load with a hostname set to their device names.
1. Click NetMap in the Menu Bar and click Apply Selected Topology. If you have another topology loaded in netSim, click Yes if prompted. To configure Router1’s host name, enter the following commands in the console:
Router>enableRouter#configure terminalRouter(config)#hostname Router1
4. Select Switch1 from Devices drop-down. To configure Switch1’s host name, enter the following commands in the console:
Switch>enableSwitch#configure terminalSwitch(config)#hostname Switch1
We now want to save our current configurations and make them loading configurations. Let’s do the following:
1. Click Console from the Menu Bar and then click Save Multi Device Config. Navigate to the TestLab folder that was created earlier on your Desktop in the Save Multiple Device Config dialog box.
3. Click Save and type Loading into the File name field.
Step 4: Create Grading Configuration Files
We now have three of the four items that can be used within our test lab. Let’s now create the final piece of the puzzle, the grading configuration file. Remember that grading configuration files are the running configuration we want our lab document user to have after they’ve finished reading it. We need to configure IP addresses and enable links on the devices in our lab document.
The following commands are required to enable a ping between Router1 and PC1 in TestLab.
On PC1:C:>ipconfig /ip 192.168.100.2 255.255.255.0C:>ipconfig /dg 192.168.100.1On Switch1:Switch1>enableSwitch1#configure terminalSwitch1(config)#ip default-gateway 192.168.100.1
On Router1:Router1>enableRouter1#configure terminalRouter1(config)#interface ethernet 0/0Router1(config-if)#ip address 192.168.100.1 255.255.255.0Router1(config-if)#no shutdown
Finally, the user should issue an ping from Router1 to PC1 with a successful ping.
On PC1:C>ping 192.168.100.1Pinging 32 bytes of data at 192.168.100.1

Once you have issued the commands previously, you can save all running configurations to all devices so you can use them for grading configurations. Follow the steps below.
1. Click Console from the Menu Bar and then click Save Multi Device Config. Navigate to the TestLab folder that was created earlier on your Desktop in the Save Multiple Device Config dialog box.
3. Click Save and type Grading into the File name field.
This is the end of part 2. Stay tuned for the last installment of this series.
