Answers Note: Rollover and mini-USB console cables are no longer automatically shipped with the newer ISR G2 routers, such as Cisco 1941, Cisco 2901, or Cisco 2911. These console cables can be purchased from Cisco Systems, Inc. or other third-party vendors.

Background / Scenario

Various models of Cisco routers and switches are used in all types of networks. These devices are managed using a local console connection or a remote connection. Nearly all Cisco devices have a serial console port to which you can connect. Some newer models, such as the 1941 Integrated Services Router (ISR) G2 used in this lab, also have a USB console port.

In this lab, you will learn how to access a Cisco device via a direct local connection to the console port, using the terminal emulation program called Tera Term. You will also learn how to configure the serial port settings for the Tera Term console connection. After you have established a console connection with the Cisco device, you can display or configure device settings. You will only display settings and configure the clock in this lab.

Note: The routers used with CCNA hands-on labs are Cisco 1941 ISRs with Cisco IOS Release 15.2(4)M3 (universalk9 image). The switches used in the labs are Cisco Catalyst 2960s with Cisco IOS Release 15.0(2) (lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers.

Note: Make sure that the switch and router have been erased and have no startup configuration. If you are unsure, contact your Answers.

Answers Note: Refer to the Answers Lab Manual for the procedures to initialize and reload devices.

Reflection

1. How do you prevent unauthorized personnel from accessing your Cisco device through the console port?
   ________________________________________________________________________________________________________________________________________________________________________
   Physically secure the device and use password protection
2. What are the advantages and disadvantages of using the serial console connection compared to the USB console connection to a Cisco router or switch?
   ________________________________________________________________________________________________________________________________________________________________________
   It depends on the port availability on the PC and the router or switch. If the PC has a serial port and a DB9-to-RJ45 cable is available, it is generally easier to connect to the router or switch using the serial console port. If the PC does not have a serial port, a third party USB-to-Serial adapter can be used. Cisco switches do not have mini-USB console ports, so connecting via USB is not an option. If you are frequently connecting to a Cisco router that has a mini USB console port, this can be the most effective method after the Cisco drivers are installed because nearly all newer PCs have USB ports.
