Part 6: (Optional) Access a Cisco Router Using a Mini-USB Console Cable
If you are using a Cisco 1941 router or other Cisco IOS devices with a mini-USB console port, you can access the device console port using a mini-USB cable connected to the USB port on your computer.
Note: The mini-USB console cable is the same type of mini-USB cables that are used with other electronics devices, such as USB hard drives, USB printers, or USB hubs. These mini-USB cables can be purchased through Cisco Systems, Inc. or other third-party vendors. Please verify that you are using a mini-USB cable, not a micro-USB cable, to connect to the mini-USB console port on a Cisco IOS device.

Note: You must use either the USB port or the RJ-45 port, and not both simultaneously. When the USB port is used, it takes priority over the RJ-45 console port used in Part 1.
Step 1: Set up the physical connection with a mini-USB cable.
a.Connect the mini-USB cable to the mini-USB console port of the router.
b.Connect the other cable end to a USB port on the computer.
c.Power up the Cisco router and computer, if these devices are not already on.
Step 2: Verify that the USB console is ready.
If you are using a Microsoft Windows-based PC and the USB console port LED indicator (labeled EN) does not turn green, please install the Cisco USB console driver.
For a Microsoft Windows-based PC connecting to a Cisco IOS device with a USB cable, a USB driver must be installed prior to use. The driver can be found on www.cisco.com with the related Cisco IOS device. The USB driver can be downloaded from the following link:
http://www.cisco.com/cisco/software/release.html?mdfid=282774238&flowid=714&softwareid=282 855122&release=3.1&relind=AVAILABLE&rellifecycle=&reltype=latest
Note: You must have a valid Cisco Connection Online (CCO) account to download this file.
Note: This link is related to the Cisco 1941 router; however, the USB console driver is not Cisco IOS device-model specific. This USB console driver only works with Cisco routers and switches. The computer requires a reboot after finishing the installation of the USB driver.
Note: After the files are extracted, the folder contains instructions for installation and removal and necessary drivers for different operating systems and architectures. Please choose the appropriate version for your system.

When the LED indicator for the USB console port has turned green, the USB console port is ready for access.
Step 3: (Optional) Enable the COM port for the Windows 7 PC.
If you are using a Microsoft Windows 7 PC, you may need to perform the following steps to enable the COM port:
a.Click the Windows Start icon to access the Control Panel.
b.Open the Device Manager.
c.Click the Ports (COM & LPT) tree link to expand it. The Cisco Virtual Comm Port00 icon displays with a yellow exclamation point attached.

d.To resolve the issue, right-click the Cisco Virtual Comm Port00 icon and choose Update Driver Software.
e.Choose Browse my computer for driver software.
f.Choose Let me pick from a list of device drivers on my computer and click Next.
© 2013 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public. Page 14 of 257
g. Choose the Cisco Serial driver and click Next.
h.The device driver is installed successfully. Take note of the port number assigned at the top of the window. In this sample, COM 6 is used for communication with the router. Click Close.

Step 4: (Optional) Determine the COM port number.
a.If you need to determine the COM port number, open the Control Panel and select the Device Manager. Search for the Ports (COM & LPT) heading, expand it, and determine the COM port number currently in use. In this example, Cisco Serial (COM 6) was selected for connection to the router because a Cisco USB console driver is in use. If you use a rollover console cable, or an adapter from a different manufacturer, the naming convention reflects this information.
b.Open Tera Term. Click the Serial radio button and choose Port COM6: Cisco Serial (COM 6). This port should now be available for communication with the router. Click OK.

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.

You will apply IP addressing for this lab to the PCs to enable communication between these two devices. Use the ping utility to verify connectivity.
Note: The switches used are Cisco Catalyst 2960s with Cisco IOS Release 15.0(2) (lanbasek9 image). Other switches and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and output produced might vary from what is shown in the labs.
Note: Make sure that the switches have been erased and have no startup configurations. Refer to Appendix A for the procedure to initialize and reload a switch.
Required Resources
2 Switches (Cisco 2960 with Cisco IOS Release 15.0(2) lanbasek9 image or comparable) 2 PCs (Windows 7, Vista, or XP with terminal emulation program, such as Tera Term) Console cables to configure the Cisco IOS devices via the console ports
Ethernet cables as shown in the topology
Part 1: Set Up the Network Topology (Ethernet only)
In Part 1, you will cable the devices together according to the network topology.
Step 1: Power on the devices.
Power on all devices in the topology. The switches do not have a power switch; they will power on as soon as you plug in the power cord.
Step 2: Connect the two switches.
Connect one end of an Ethernet cable to F0/1 on S1 and the other end of the cable to F0/1 on S2. You should see the lights for F0/1 on both switches turn amber and then green. This indicates that the switches have been connected correctly.
Step 3: Connect the PCs to their respective switches.
Connect one end of the second Ethernet cable to the NIC port on PC-A. Connect the other end of the cable to F0/6 on S1. After connecting the PC to the switch, you should see the light for F0/6 turn amber and then green, indicating that PC-A has been connected correctly.
Connect one end of the last Ethernet cable to the NIC port on PC-B. Connect the other end of the cable to F0/18 on S2. After connecting the PC to the switch, you should see the light for F0/18 turn amber and then green, indicating that the PC-B has been connected correctly.
Step 4: Visually inspect network connections.
After cabling the network devices, take a moment to carefully verify the connections to minimize the time required to troubleshoot network connectivity issues later.
