Activities.
3.1.1
3.1.2
3.1.3
3.1.4
Write the command needed to change from
privileged exec mode to global config mode
and the resulting prompt.
Config t
Router(config)#
List the modes that can be entered from
global config mode.
Interface mode
Line mode
Router mode
Subinterface mode
Controller mode
Explain the difference between Exit and
Ctrl-Z.
Exit lets you back out of that particular configuration
mode into global config mode. Ctrl-Z moves you back
to the privileged exec prompt.
List the command including the prompt
needed to configure the hostname of a
router to “Hawaii”. Write the new prompt
below the command.
Router(config)#hostname Hawaii
Hawaii(config)#
List the commands needed including the
prompts, to set the Console port’s password
to class.
Router(config)#line console 0
Router(config-line)#password class
Router(config-line)#login
It’s not in the curriculum, but find out why
the login command is needed when setting
up lines.
Without the login line, the user wouldn’t be prompted
for a password and wouldn’t be able to get in.
How many VTY (telnet) lines do typical
Cisco routers support?
5
How is the command sequence for setting
up VTY lines different from the console
port?
Line console 0 changes to line vty 0 4
What is the difference between enable
secret and enable password?
Enable secret is encrypted. Enable password is not.
Both protect the privileged exec mode from unauthorized
access.
What command can be used to protect the
line passwords from being viewed in the
configuration files?
Service password-encryption
Which mode has more show commands
and how can you see them?
Privileged exec has more. Type show? to see a listing.
List the commands needed to perform :
3.1.5
1. Enter global configuration mode
2. Enter interface mode for s 0/1
3. Specify the interface address and
subnet mask of 100.150.200.1 &
255.0.0.0
4. Set clock rate of 56000.
5. Turn on the interface

How do you save the changes you’ve made
to the running configuration? At which
prompt?
Type copy running-config startup-config at the privileged
exec prompt.
How do you view the current configuration
and at what prompt?
Type show running-config at the privileged exec prompt.
List the steps needed to configure the
Ethernet interface on a router.
1.

3.
4.
Enter global configuration mode
Enter interface configuration mode
Specify the interface address and subnet mask
Enable the interface
Why is the command no shutdown issued
after configuring an interface?
An interface is disabled each time it is configured.
You must type no shut to re-enable it.
3.1.7
It aids in the documentation of the network. It may
help the user know where the interface is located, who
configured it, what it’s attached to, etc. It doesn’t
affect the operation of the interface.
Config t
Interface serial 1
Description connected to WAN link at corp. hq
No shut
3.2.2
Why would a network administrator include
a description when configuring an interface
on a router?
3.2.3
From the privileged exec prompt, list the
commands needed to place the description
“connected to WAN link at corp. hq” to the
Serial 1 interface. (hint: there are 4 lines)
3.2.4
What is the purpose of a login banner?
It alerts anyone accessing the router to pertinent
information such as planned network outages.
3.2.5
List the commands needed to create a
banner stating “Next scheduled outage is
2/14 at 0100.” from the privileged exec
prompt. Be sure to save your configuration.
(hint: again 4 lines are needed)
Configure terminal
Banner motd # Next scheduled outage is 2/14 at 0100 #
Exit
Copy running-config startup-config
3.2.6
Explain the purpose of a host table.
A host table associates host names with IP addresses.
They are significant only on the router, unlike DNS
names.
3.2.8
List the places configuration files should be
stored when they are backed up.
TFTP server, network server, disk in a safe place
3.2.9
List the steps needed to back up the router
configuration to a TFTP server. Note: The
TFTP server software must be running
on the computer, and the computer and
router must be configured properly to
establish this connection.
1.
2.
3.
4.
Enter global configuration mode
Enter interface configuration mode
Specify the interface address and subnet mask
Enable the interface
