Create and name two VLANs
Enter the
following commands to create and name two VLANs:
Switch_A#vlan
database
Switch_A(vlan)#vlan 2
name VLAN2
Switch_A(vlan)#vlan 3
name VLAN3
Switch_A(vlan)#exit
Assign ports to VLAN 2
Assigning
ports to VLANs must be done from the interface mode. Enter the following
commands to
add port
2 to VLAN 2:
Switch_A#configure
terminal
Switch_A(config)#interface
fastethernet 0/2
Switch_A(config-if)#switchport
mode access
Switch_A(config-if)#switchport
access vlan 2
Switch_A(config-if)#end

Assign ports to VLAN 2
Assigning
ports to VLANs must be done from the interface mode. Enter the following
commands to
add ports
4, 5 and 6 to VLAN 2.
Switch_A#configure
terminal
Switch_A(config)#interface
fastethernet 0/4
Switch_A(config-if)#switchport
mode access
Switch_A(config-if)#switchport
access vlan 2
Switch_A(config-if)#interface
fastethernet 0/5
Switch_A(config-if)#switchport
mode access
Switch_A(config-if)#switchport
access vlan 2
Switch_A(config-if)#interface
fastethernet 0/6
Switch_A(config-if)#switchport
mode access
Switch_A(config-if)#switchport
access vlan 2
Switch_A(config-if)#end
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
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]
