Lab Objective:
Learn how to connect to a router or switch using a modem.
Lab Purpose:
Along with console connections, modems are an out-of-band connection option for network equipment. ‘Out-of-band’ refers to a data stream independent of the usual connection stream, such as a DSL or leased line. It is often used for emergency access and is physically connected only when needed for security purposes.
Lab Tool:

Lab Walkthrough:
Task 1:
Connect a modem card to your PC in PT and to the router. You will need to power them off before doing so. Power both devices back on. You click on the card name and then physically drag the image onto the slot. The modem in the above image is to illustrate the fact that it’s installed inside the PC.
Task 2:
Drag a PT cloud onto the canvas. Connect the PC modem port to port 4, and port 5 to the router modem port. Use a phone cable.
Task 3:
Assign phone number 444 to modem interface 4 and 555 to modem interface 5.
Task 4:
Assign a username and password to the router.
Router(config)#username 101labs password hello
Task 5:
Assign IP address 192.168.1.1 to the router modem interface.
Task 6:
On the PC, assign IP address 192.168.1.2 and default gateway 192.168.1.1 to the modem interface.
Task 7:
On the PC, go to a modem interface (dial-up) and enter the username and password. Put the dial number as 555 and hit ‘Dial’.
Task 8:
You should now be connected.
Notes:
You should be able to ping the router from the host after the connection comes up. I couldn’t, but this may be a limitation of PT, which is just a network emulator.
