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 VLAN
configuration commands.
This example shows how 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.

Deleting a VLAN

When you delete a VLAN from a switch that is in VTP server mode, the VLAN is removed from the
VLAN database for all switches in the VTP domain. When you delete a VLAN from a switch that is in
VTP transparent mode, the VLAN is deleted only on that specific switch or a switch stack.
You cannot delete the default VLANs for the different media types: Ethernet VLAN 1 and FDDI or
Token Ring VLANs 1002 to 1005.
When you delete a VLAN, any ports assigned to that VLAN become inactive. They remain associated
Caution
with the VLAN (and thus inactive) until you assign them to a new VLAN.
Beginning in privileged EXEC mode, follow these steps to delete a VLAN on the switch:
Command
Step 1 configure terminal
Step 2
no vlan vlan-id
Step 3 end
OL-12247-04
Purpose
(Optional) Enter a name for the VLAN. 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) Change the MTU size (or other VLAN characteristic).
(Optional) Configure the VLAN as the RSPAN VLAN for a remote
SPAN session. For more information on remote SPAN, see
"Configuring SPAN and RSPAN."
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.
Purpose
Enter global configuration mode.
Remove the VLAN by entering the VLAN ID.
Return to privileged EXEC mode.
