In-Depth Information
From global configuration mode, configure the message-of-the-day banner. Use the following text:
Authorized Access Only . A delimiting character, such as a #, is used at the beginning and at the end
of the message.
R1(config)# banner motd # Authorized Access Only #
What is the purpose of the message of the day?
At a minimum, a banner should warn against unauthorized access. Never configure a banner that
“welcomes” an unauthorized user.
Refer to Figure 1-5 for the correct interface designations. What is the command to enter interface con-
figuration mode for R1's serial interface?
R1(config)# interface Serial0/0/0
Enter the command to configure the IP address using the address you specified in Table 1-1.
R1(config-if)# ip address 172.17.0.1 255.255.255.0
Describe the interface with the following text: Link to R2 .
R1(config-if)# description Link to R2
Because R1 is on the data communications equipment (DCE) side, set the clocking signal to 64000 .
R1(config-if)# clock rate 64000
Activate the interface.
Router(config-if)# no shutdown
Now enter the commands to configure and activate the Fast Ethernet interface on R1. Use the follow-
ing description text: R1 LAN .
R1(config)# interface FastEthernet0/0
R1(config-if)# ip address 172.16.0.1 255.255.255.0
R1(config-if)# description R1 LAN
R1(config-if)# no shutdown
What command will save the current configuration?
Router# copy running-config startup-config
