Look at only VLAN2 information

a. Instead of displaying all of the VLANs type the show vlan id 2 command at the Privileged

EXEC mode prompt as follows:

Switch_A#show vlan id 2

Look at only VLAN2 information with a different command (1900: Omit this step)

a. Instead of displaying all of the VLANs type the show vlan name VLAN2 command at the

Privileged EXEC mode prompt.

Switch_A#show vlan name VLAN2

Test the VLANs

Ping from the host in port 0/4 to the host in port 0/1.

a. Was the ping successful? No

b. Why? Different vlan membership

Ping from the host in port 0/1 to the host in port 0/4.

c. Was the ping successful? No

d. Why? Different vlan membership

Ping from the host in port 0/4 to the switch IP 192.168.1.2.

e. Was the ping successful? No

f. Why? Different vlan membership

Ping from the host in port 0/1 to the switch IP 192.168.1.2.

Deleting VLAN Configurations – 2950 Series

Delete a Host from a VLAN

To remove a host from a VLAN, use the no form of the switchport commands in the port interface

configuration mode.

Switch_A#configure terminal

Switch_A(config)#interface fastethernet 0/4

Switch_A(config-if)#no switchport access vlan 2

Delete VLAN 1

a. Try to delete VLAN 1, which is the default VLAN, the same way that you deleted VLAN 3.

Switch_A#vlan database

Switch_A(vlan)#no vlan 1

A default VLAN may not be deleted.

Switch_A(vlan)#exit

Erasing and Reloading the Switch

For the majority of the labs in CCNA 3 and CCNA 4 it is necessary to start with an unconfigured

switch. Use of a switch with an existing configuration may produce unpredictable results. These

instructions allow preparation of the switch prior to performing the lab so previous configuration

options do not interfere. The following is the procedure for clearing out previous configurations and

starting with an unconfigured switch. Instructions are provided for the 2900, 2950, and 1900 Series

switches.

2900 and 2950 Series Switches

1. Enter into the Privileged EXEC mode by typing enable.

If prompted for a password, enter class (if that does not work, ask the instructor).

Switch>enable

2. Remove the VLAN database information file.

Switch#delete flash:vlan.dat

Delete filename [vlan.dat]?[Enter]

Delete flash:vlan.dat? [confirm] [Enter]

If there was no VLAN file, this message is displayed.

%Error deleting flash:vlan.dat (No such file or directory)

3. Remove the switch startup configuration file from NVRAM.

Switch#erase startup-config

The responding line prompt will be:

Erasing the nvram filesystem will remove all files! Continue? [confirm]

Press Enter to confirm.

The response should be:

Erase of nvram: complete

4. Check that VLAN information was deleted.

Verify that the VLAN configuration was deleted in Step 2 using the show vlan command. If

previous VLAN configuration information (other than the default management VLAN 1) is still

present it will be necessary to power cycle the switch (hardware restart) instead of issuing the

reload command. To power cycle the switch, remove the power cord from the back of the

switch or unplug it. Then plug it back in.

If the VLAN information was successfully deleted in Step 2, go to Step 5 and restart the switch

using the reload command.

5. Software restart (using the reload command)

Note: This step is not necessary if the switch was restarted using the power cycle method.

a. At the Privileged EXEC mode enter the command reload.

Switch#reload

The responding line prompt will be:

System configuration has been modified. Save? [yes/no]:

b. Type n and then press Enter.

The responding line prompt will be:

Proceed with reload? [confirm] [Enter]

The first line of the response will be:

Reload requested by console.

After the switch has reloaded, the line prompt will be:

Would you like to enter the initial configuration dialog? [yes/no]:

c. Type n and then press Enter.

The responding line prompt will be:

Press RETURN to get started! [Enter]

Switch interfaces configuration

Lab instructions

This lab will test your ability to configure speed, duplex, and vlan settings on a cisco switchinterfaces.

1. Connect to Switch0 using console interface and configure each Switch0 fastethernet switchport for operation. Correct settings are :
- Port type : access port
- Speed : 100 Mbit/s
- Duplex mode : Full Duplex
- Autonegotiation disabled

2. PC “192.168.1.4″ seems to be unable to ping other PCs in the network. Check switch configuration.
TIP : How many broadcast domains are there in this network ?

3. Choose the right cable to connect :
- Switch0 gigabitethernet 1/1 to Switch1 gigabitethernet 1/1
- Switch1 gigabitethernet 1/2 to Switch2 gigabitethernet 1/2

4. Configure those two links as trunk lines without using trunk negotiation between switches

Solution

Connect to Switch0 using console interface and configure each Switch0 fastethernet switchport for operation.

Switch(config)#interface FastEthernet0/1

switchport mode access
duplex full
speed 100

Switch(config)#interface FastEthernet0/2

switchport mode access
duplex full
speed 100

Switch(config)#interface FastEthernet0/3

switchport mode access
duplex full
speed 100

Switch(config)#interface FastEthernet0/4

switchport mode access
duplex full

PC “192.168.1.4″ seems to be unable to ping other PCs in the network. Check switch configuration.
Switch(config)#interface FastEthernet0/4

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 1
Choose the right cable to connect :
- Switch0 gigabitethernet 1/1 to Switch1 gigabitethernet 1/1
- Switch1 gigabitethernet 1/2 to Switch2 gigabitethernet 1/2

lab2-networkdiagram-solution

Configure those two links as trunk lines without using trunk negotiation between switches

On every interface that has to be configured for trunk operation, configure the following settings

Switch(config)#interface GigabitEthernet1/X

Switch(config-if)#switchport mode trunk

Verify interface operational mode using the “show interface GigabitEthernet1/X switchport command” :

Name: Gig1/2

Switchport: Enabled

Administrative Mode: trunk

Operational Mode: trunk

Administrative Trunking Encapsulation: dot1q

Operational Trunking Encapsulation: dot1q

Negotiation of Trunking: On

Access Mode VLAN: 1 (default)

Trunking Native Mode VLAN: 1 (default)

Voice VLAN: none

Another usefull ios command is “show interfaces trunk” :

Switch#sh interfaces trunk
Port Mode Encapsulation Status Native vlan
Gig1/2 on 802.1q trunking 1

Port Vlans allowed on trunk
Gig1/2 1-1005

Port Vlans allowed and active in management domain
Gig1/2 1

Port Vlans in spanning tree forwarding state and not pruned
Gig1/2 1
