Context / Scenario
The switch virtual interface is an IP address that can be configured on Cisco switches (SVI). The management address, or SVI, can be used for remote access to the switch in order to display or configure settings. If an IP address is assigned to the SVI of VLAN 1, all ports in VLAN 1 have access to that IP address by default.
In this lab, you will construct a simple Ethernet LAN topology and access a Cisco switch via console and remote access methods. You will review the default switch configurations prior to configuring the switch's fundamental settings. These settings comprise the device name, interface description, local passwords, MOTD banner, IP addressing, and static MAC address. Additionally, you will demonstrate the utilisation of a management IP address for remote switch management. The network architecture consists of a single switch and a single host with only Ethernet and console ports.
Cisco Catalyst 2960 switches with Cisco IOS Release 15.2(2) are used (lanbasek9 image). Other switches and versions of Cisco IOS are supported. Depending on the model and Cisco IOS version, the available commands and output may differ from what is demonstrated in the labs.
Note: Ensure the switches have been cleared of all startup configurations. If you are unclear, contact your Answers. Refer to Appendix A for switch initialization and reloading procedures.
Refer to the Answers Lab Manual for instructions on how to initialise and reload devices.
The default bias template utilised by the Switch Database Manager (SDM) lacks IPv6 address support. Verify that SDM is utilising either the dual-ipv4-and-ipv6 or lanbase-routing template. Even if the configuration isn't saved, the new template will be used after a reboot.
Launch configuration display
S1# prefer sdm display
The dual-ipv4-and-ipv6 template will be assigned as the default SDM template using the commands below.
S1# setup terminal
S1(config)# sdm prefer dual-ipv4-and-ipv6 default
S1(config)# end
S1# reload

Essential Resources
1 Switch (Cisco 2960 equipped with Cisco IOS Release 15.2(2) lanbasek9 image or equivalent)
1 PC (Windows with terminal emulation application, such as Tera Term) (Windows with terminal emulation program, such as Tera Term)
1 Console cable for configuring a Cisco IOS device through its console port
1 Ethernet cable according to the network topology
Connect the network cables and confirm the default switch configuration.
In Part 1, you will configure the network topology and confirm the switch's default settings.
Step 1: Wire the network according to its topology.
Connect the console cable per the topology diagram. Do not currently connect the PC-A Ethernet cable.
Note: If you are utilising Netlab, disable F0/6 on S1. This has the same effect as if PC-A were not connected to S1.
Connect PC-A to the switch using Tera Term or an alternative terminal emulation programme.
Question:
Why is a console connection required for initial switch configuration? Why is a Telnet or SSH connection to the switch not possible?
No IP addressing parameters are currently configured. A newly installed Cisco 2960 switch has no networking configuration.
Step 2: Verify the switch's default configuration.
Examine the default switch settings, including the current switch configuration, IOS information, interface properties, VLAN information, and flash memory, in this step.
In privileged EXEC mode, you have access to all switch IOS commands. Because it provides direct access to global configuration mode and commands used to configure operating parameters, access to the privileged EXEC mode should be password-protected to prevent unauthorised use. In the future, you will set passwords in this lab.
The privileged EXEC mode command set contains the same commands as user EXEC mode, in addition to the configure command, which grants access to the remaining command modes. Use the enable command to enter EXEC mode with privileges.
Assuming there was no configuration file stored in the switch's nonvolatile random-access memory (NVRAM), a console connection using Tera Term or another terminal emulation programme will place you at the user EXEC mode prompt with the prompt Switch>. Use the enable command to enter EXEC mode with privileges.
Launch configuration display
Switch> allow
Switch#
Notice how the configuration prompt changed to reflect privileged EXEC mode.
Verify that there is a clean default configuration file on the switch by issuing the show running-config privileged EXEC mode command. If a configuration file has been saved previously, it must be deleted. Depending on the switch model and IOS version, the appearance of your configuration may vary slightly. However, neither a password nor an IP address should be configured. If your switch does not have a default configuration, erase and reload the switch.
Note: Appendix A details the steps to initialise and reload a switch.
Examine the current running configuration file.
Switch# show running-config
Questions:
How many FastEthernet interfaces does a 2960 switch have?
24
How many Gigabit Ethernet interfaces does a 2960 switch have?
2
What is the range of values shown for the vty lines?
0-4 and 5-15 or 0-15
Examine the startup configuration file in NVRAM.
Switch# show startup-config
startup-config is not present
Question:
Why does this message appear?
No configurations have been saved to NVRAM.
Examine the characteristics of the SVI for VLAN 1.
Switch# show interface vlan1
Questions:
Is there an IP address assigned to VLAN 1?
No
What is the MAC address of this SVI? Answers will vary.
0CD9:96E2:3D40 in this case.
Is this interface up?
Cisco switches have the no shutdown command configured by default on VLAN 1, but VLAN 1 will not reach the up/up state until a port is assigned to it and this port is also up. If there is no port in the up state in VLAN 1, then the VLAN 1 interface will be up, line protocol down. By default, all ports are assigned initially to VLAN 1.
Examine the IP properties of the SVI VLAN 1.
Switch# show ip interface vlan1
Question:
What output do you see?
Vlan1 is up, line protocol is down
Internet protocol processing disabled
Connect an Ethernet cable from PC-A to port 6 on the switch and examine the IP properties of the SVI VLAN 1. Allow time for the switch and PC to negotiate duplex and speed parameters.
Note: If you are using Netlab, enable interface F0/6 on S1.
Switch# show ip interface vlan1
Question:
What output do you see?
Vlan1 is up, line protocol is up
Internet protocol processing disabled
Examine the Cisco IOS version information of the switch.
Switch# show version
Questions:
What is the Cisco IOS version that the switch is running?
/span>.
Answers may vary.
What is the system image filename?
/span>.
Answers may vary.
What is the base MAC address of this switch?
Answers will vary.
Examine the default properties of the FastEthernet interface used by PC-A.
Switch# show interface f0/6
Question:
Is the interface up or down?
It should be up unless there is a cabling problem.
What event would make an interface go up?
Connecting a host or other device
What is the MAC address of the interface?
Answers will vary.
What is the speed and duplex setting of the interface?
Full-duplex, 100Mb/s
Examine the default VLAN settings of the switch.
Switch# show vlan
Question:
What is the default name of VLAN 1?
default
Which ports are in VLAN 1?
all ports; F0/1 – F0/24; G0/1, G0/2
Is VLAN 1 active?
Yes
What type of VLAN is the default VLAN?
enet (Ethernet) (Ethernet)
Examine flash memory.
Issue one of the following commands to examine the contents of the flash directory.
Switch# show flash
Switch# dir flash:
Files have a file extension, such as .bin, at the end of the filename. Directories do not have a file extension.
Question:
What is the filename of the Cisco IOS image?
Answers will vary.
Part 2: Configure Basic Network Device Settings
In Part 2, you will configure basic settings for the switch and PC.
Step 1: Configure basic switch settings.
Copy the following basic configuration and paste it into S1 while in global configuration mode.
no ip domain-lookup
hostname S1
service password-encryption
allow hidden class
banner motd #
Unauthorized access is strictly prohibited. #
Set the SVI IP address of the switch. This allows remote management of the switch.
Before you can manage S1 remotely from PC-A, you must assign the switch an IP address. The default configuration on the switch is to have the management of the switch controlled through VLAN 1. However, a best practise for basic switch configuration is to change the management VLAN to a VLAN other than VLAN 1.
For administration reasons, use VLAN 99. The selection of VLAN 99 is arbitrary and in no way implies that you should always use VLAN 99.
First, create the new VLAN 99 on the switch. Then set the IP address of the switch to 192.168.1.2 with a subnet mask of 255.255.255.0 on the internal virtual interface VLAN 99. IPv6 address can also be configured on the SVI interface. Use the IPv6 addresses listed in the Addressing Table.
S1# setup terminal
S1(config)# vlan 99
S1(config-vlan)# quit
S1(config)# interface vlan99
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan99, changed state to down
S1(config-if)# ip address 192.168.1.2 255.255.255.0
S1(config-if)# ipv6 address 2001:db8:acad::2/64
S1(config-if)# ipv6 address fe80::2 link-local
S1(config-if)# no shutdown
S1(config-if)# exit
Notice that the VLAN 99 interface is in the down state even though you entered the no shutdown command. The interface is currently down because no switch ports are assigned to VLAN 99.
Assign all user ports to VLAN 99.
S1(config)# interface range f0/1 – 24,g0/1 – 2
S1(config-if-range)# switchport access vlan 99
S1(config-if-range)# exit
S1(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan99, changed state to up
To establish connectivity between the host and the switch, the ports used by the host must be in the same VLAN as the switch. Notice in the above output that the VLAN 1 interface goes down because none of the ports are assigned to VLAN 1. After a few seconds, VLAN 99 comes up because at least one active port (F0/6 with PC-A attached) is now assigned to VLAN 99.
Issue the show vlan brief command to verify that all ports are in VLAN 99.
S1# display vlan short

Configure the default gateway for S1. If no default gateway is set, the switch cannot be managed from a remote network that is more than one router away. Although this activity does not include an external IP gateway, assume that you will eventually connect the LAN to a router for external access. Assuming that the LAN interface on the router is 192.168.1.1, set the default gateway for the switch.
S1(config)# ip default-gateway 192.168.1.1
Console port access should also be restricted with a password. Use cisco as the console login password in this activity. The default configuration is to allow all console connections with no password needed. To prevent console messages from interrupting commands, use the logging synchronous option.
S1(config)# line con 0
S1(config-line)# logging synchronous
S1(config-line)# password cisco
S1(config-line)# login
S1(config-line)# exit
Configure the virtual terminal (vty) lines for the switch to allow telnet access. If you do not configure a vty password, you will not be able to telnet to the switch.
S1(config)# line vty 0 15
S1(config-line)# password cisco
S1(config-line)# login
S1(config-line)# end
S1#
*Mar 1 00:06:11.590: %SYS-5-CONFIG I: Configured from console by console
Question:
Why is the login command required?
Without the login command, the switch will not prompt for a password.
Close configuration window
Step 2: Configure an IP address on PC-A.
Assign the IP address and subnet mask to the PC as shown in the Addressing Table. An abbreviated version of the procedure is described here. A default gateway is not required for this topology; however, you can enter 192.168.1.1 and fe80::1 to simulate a router attached to S1.
1) Navigate to the Control Panel.
2) In the Category view, select View network status and tasks.
3) Click Change adapter settings on the left panel.
4) Right-click an Ethernet interface, and choose Properties.
5) Choose Internet Protocol Version 4 (TCP/IPv4) and click Properties.
6) Click the Use the following IP address radio button and enter the IP address and subnet mask and click OK.
7) Select Internet Protocol Version 6 (TCP/IPv6) and click Properties.
8) Click the Use the following IPv6 address radio button and enter the IPv6 address and prefix and click OK to continue
9) Click OK to exit the Properties window.
Part 3: Verify and Test Network Connectivity
In Part 3, you will verify and document the switch configuration, test end-to-end connectivity between PC-A and S1, and test the switch’s remote management capability.
Step 1: Display the switch configuration.
Use the console connection on PC-A to display and verify the switch configuration. The show run command displays the entire running configuration, one page at a time. Use the spacebar to advance paging.
A sample configuration is shown here. The settings you configured are highlighted in yellow. The other configuration settings are IOS defaults.

Step 2: Test end-to-end connectivity with ping.
From the command prompt on PC-A, ping the address of PC-A first.
C:\> ping 192.168.1.10
From the command prompt on PC-A, ping the SVI management address of S1.
C:\> ping 192.168.1.2
Because PC-A needs to resolve the MAC address of S1 through ARP, the first packet may time out. If ping results continue to be unsuccessful, troubleshoot the basic device configurations. Check both the physical cabling and logical addressing.
Step 3: Test and verify remote management of S1.
You will now use Telnet to remotely access the switch. In this lab, PC-A and S1 reside side by side. In a production network, the switch could be in a wiring closet on the top floor while your management PC is located on the ground floor. In this step, you will use Telnet to remotely access switch S1 using its SVI management address. Telnet is not a secure protocol; however, you will use it to test remote access. With Telnet, all information, including passwords and commands, are sent across the session in plain text. In subsequent labs, you will use SSH to remotely access network devices.
Open Tera Term or other terminal emulation programme with Telnet capability.
Select the Telnet server and provide the SVI management address to connect to S1. The password is cisco.
After entering the password cisco, you will be at the user EXEC mode prompt. Access privileged EXEC mode using the enable command and providing the secret password class.
Save the configuration.
S1# copy running-config startup-config
Destination filename [startup-config]? [Enter]
Building configuration…
[OK]
Type exit to end the Telnet session.
Part 4: Manage the MAC Address Table
In Part 4, you will determine the MAC addresses that the switch has learned, set up a static MAC address on one interface of the switch, and then remove the static MAC address from that interface.
Step 1: Record the MAC address of the host.
Open a command prompt on PC-A and issue the ipconfig /all command to determine and record the Layer 2 (physical) addresses of the NIC.
Answers will vary.
Step 2: Determine the MAC addresses that the switch has learned.
Open configuration window
Display the MAC addresses using the show mac address-table command.
S1# show mac address-table
Questions:
How many dynamic addresses are there?
1 (may vary) (can vary)
How many MAC addresses are there in total?
24 (may vary) (can vary)
Does the dynamic MAC address match the MAC address of PC-A?
Yes
Step 3: List the show mac address-table options.
Display the MAC address table options.
S1# show mac address-table ?
Question:
How many options are available for the show mac address-table command?
12 (may vary) (can vary)
Issue the show mac address-table dynamic command to display only the MAC addresses that were learned dynamically.
S1# show mac address-table dynamic
Question:
How many dynamic addresses are there?
1 (may vary) (can vary)
View the MAC address entry for PC-A. The MAC address formatting for the command is xxxx.xxxx.xxxx.
S1# show mac address-table address <PC-A MAC here>
Step 4: Set up a static MAC address.
Clear the MAC address table.
To remove the existing MAC addresses, use the clear mac address-table dynamic command in privileged EXEC mode.
S1# clear mac address-table dynamic
Verify that the MAC address table was cleared.
S1# show mac address-table
Question:
How many static MAC addresses are there?
at least 20 (other static entries could have been manually created) (other static entries could have been manually created)
Answers Note: The first 20 static addresses in the MAC address table are built-in.
How many dynamic addresses are there?
0 (may be 1, depending on how rapidly addresses are re–acquired by the transition) (may be 1, depending on how quickly addresses are re–acquired by the switch)
Examine the MAC table again.
More than likely, an application running on your PC has already sent a frame out the NIC to S1. Look at the MAC address table again in privileged EXEC mode to see if S1 has relearned the MAC address of PC-A.
S1# show mac address-table
Questions:
How many dynamic addresses are there?
1
Why did this change from the last display?
The switch dynamically reacquired the PC MAC address.
If S1 has not yet relearned the MAC address for PC-A, ping the VLAN 99 IP address of the switch from PC-A, and then repeat the show mac address-table command.
Set up a static MAC address.
To specify which ports a host can connect to, one option is to create a static mapping of the host MAC address to a port.
Set up a static MAC address on F0/6 using the address that was recorded for PC-A in Part 4, Step 1. The MAC address 0050.56BE.6C89 is used as an example only. You must use the MAC address of PC-A, which is different than the one given here as an example.
S1(config)# mac address-table static 0050.56BE.6C89 vlan 99 interface fastethernet 0/6
Verify the MAC address table entries.
S1# show mac address-table
Questions:
How many total MAC addresses are there?
22 (varies) (varies)
How many static addresses are there?
There are 22 static addresses. Total MAC addresses and static addresses should be the same because there are no other devices currently connected to S1.
Remove the static MAC entry. Enter global configuration mode and remove the command by putting a no in front of the command string.
Note: The MAC address 0050.56BE.6C89 is used in the example only. Use the MAC address for PC-A.
S1(config)# no mac address-table static 0050.56BE.6C89 vlan 99 interface fastethernet 0/6
Verify that the static MAC address has been cleared.
S1# show mac address-table
Question:
How many total static MAC addresses are there?
21 (varies) (varies)
