Configuring Normal-Range VLANs
Command
Step 7 show vlan {name vlan-name | id vlan-id} Verify your entries.
Step 8
copy running-config startup config
To return the VLAN name to the default settings, use the no name, no mtu, or no remote-span
config-vlan commands.
This example shows how to use config-vlan mode to create Ethernet VLAN 20, name it test20, and add
it to the VLAN database:
Switch# configure terminal
Switch(config)# vlan 20
Switch(config-vlan)# name test20
Switch(config-vlan)# end
You can also create or modify Ethernet VLANs by using the VLAN database configuration mode.
VLAN database configuration mode does not support RSPAN VLAN configuration or extended-range
Note
VLANs.
Beginning in privileged EXEC mode, follow these steps to use VLAN database configuration mode to
create or modify an Ethernet VLAN:
Command
Step 1 vlan database
Step 2 vlan vlan-id name vlan-name
Step 3 vlan vlan-id mtu mtu-size
Step 4 exit
Step 5 show vlan {name vlan-name | id vlan-id} Verify your entries.
Step 6
copy running-config startup config
To return the VLAN name to the default settings, use the no vlan vlan-id name or no vlan vlan-id mtu
VLAN database configuration command.

Purpose
(Optional) If the switch is in VTP transparent mode, the VLAN
configuration is saved in the running configuration file as well as in the
VLAN database. This saves the configuration in the switch startup
configuration file.
Purpose
Enter VLAN database configuration mode.
Add an Ethernet VLAN by assigning a number to it. The range is 1 to
1001. You can create or modify a range of consecutive VLANs by
entering vlan first-vlan-id end last-vlan-id.
When entering a VLAN ID in VLAN database configuration
Note
mode, do not enter leading zeros.
If no name is entered for the VLAN, the default is to append the vlan-id
with leading zeros to the word VLAN. For example, VLAN0004 is a
default VLAN name for VLAN 4.
(Optional) To modify a VLAN, identify the VLAN and change a
characteristic, such as the MTU size.
Update the VLAN database, propagate it throughout the administrative
domain, and return to privileged EXEC mode.
(Optional) If the switch is in VTP transparent mode, the VLAN
configuration is saved in the running configuration file as well as in the
VLAN database. This saves the configuration in the switch startup
configuration file.
