Backgroun
nd / Scenarrio
Various models
m
of Cisc
co routers and
d switches are used in netw
tworks of all tyypes. These d
devices are m
managed
using a lo
ocal console connection
c
or a remote con
nnection. Nea
arly all Cisco d
devices have a serial conssole port
to which you
y can conne
ect. Some ne
ewer models, such as the 1
1941 Integrate
ed Services R
Router (ISR) G
G2 used
in this lab, also have a USB console
e port.
In this lab
b, you will learrn how to access a Cisco device
d
via a d
direct local co nnection to th
he console po
ort, using
a terminal emulation prrogram, Tera Term. You will
w also learn how to config
gure the seria
al port settingss for the
Tera Term
m console con
nnection. Afte
er you have es
stablished a cconsole connection with th
he Cisco devicce, you
can displa
ay or configurre device settings. You will only display settings and configure the
e clock with th
his lab.
Note: The
e routers used
d with CCNA hands-on lab
bs are Cisco 1
1941 ISRs witth Cisco IOS Release 15.2
2(4)M3
(universallk9 image). The switches used
u
are Cisc
co Catalyst 29
960s with Ciscco IOS Relea
ase 15.0(2) (la
anbasek9
image). Other
O
routers, switches, and
d Cisco IOS versions
v
can be used. Dep
pending on the model and Cisco
IOS versio
on, the comm
mands availab
ble and outputt produced m ight vary from
m what is show
wn in the labss. Refer
to the Rou
uter Interface Summary Ta

u to
access the command line interface (CLI) and display settings or configure the switch.
S
Step 1: Con
nnect a Cisc
co switch and
a
computer using a rrollover con
nsole cable.
a. Connect the rollove
er console ca
able to the RJ-45 console p
port of the sw
witch.
b. Connect the other cable end to the serial CO
OM port on the
e computer.
Note: Serial COM ports are no longer availab
ble on most ccomputers tod
day. A USB-to
o-DB9 adapte
er can be
used with the rollov
ver console cable
c
for cons
sole connectio
on between th

and a Cisco d
device.
These

9 adapters ca
an be purchas
sed at any co mputer electrronics store.
Note: If using a US
SB-to-DB9 ad
dapter to conn
nect to the CO

es with a mini-USB consolle port, you ca
an access
the device
e console porrt using a mini-USB cable connected

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.
