Lab - Establishing a Console Session with Tera Term


Part 1: Access a Cisco Switch through the Serial Console Port
Part 2: Display and Configure Basic Device Settings
Part 3: (Optional) Access a Cisco Router Using a Mini-USB Console Cable

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 instructor.

Required Resources
 1 Router (Cisco 1941 with Cisco IOS software, release 15.2(4)M3 universal image or comparable)
 1 Switch (Cisco 2960 with Cisco IOS Release 15.0(2) lanbasek9 image or comparable)
 1 PC (Windows 7 or 8 with a terminal emulation program, such as Tera Term)
 Rollover (DB-9 to RJ-45) console cable to configure the switch or router via the RJ-45 console port
 Mini-USB cable to configure the router via the USB console port
You will connect a PC to a Cisco switch using a rollover console cable. This connection will allow you to
access the CLI and display settings or configure the switch.
