Chapter12 Configuring VLANs Configuring Normal-Range VLANs
VLAN Configuration Mode Options
You can configure normal-range VLANs (with VLAN IDs 1 to 1005) by using these two configuration
modes:
•VLAN Configuration in config-vlan Mode, page 12-7
You access config-vlan mode by entering the vlan vlan-id global configuration command.
•VLAN Configuration in VLAN Database Configuration Mode, page 12-7
You access VLAN database configuration mode by entering the vlan database privileged EXEC
command.

VLAN Configuration in config-vlan Mode

To access config-vlan mode, enter the vlan global configuration command with a VLAN ID. Enter a new
VLAN ID to create a VLAN, or enter an existing VLAN ID to modify that VLAN. You can use the
default VLAN configuration (Table 12-2) or enter multiple commands to configure the VLAN. For more
information about commands available in this mode, see the vlan global configuration comm and
description in the command reference for this release. When you have finished the configuration, you
must exit config-vlan mode for the configuration to take effect. To display the VLAN configuration,
enter the show vlan privileged EXEC command.
You must use this config-vlan mode when creating extended-range VLANs (VLAN IDs greater than
1005). See the “Configuring Extended-Range VLANs” section on page 12-12.

VLAN Configuration in VLAN Database Configuration Mode

To access VLAN database configuration mode, enter the vlan database privileged EXEC command.
Then enter the vlan command with a new VLAN ID to create a VLAN, or enter an existing VLAN ID
to modify the VLAN. You can use the default VLAN configuration (Tabl e 12-2) or enter multiple
commands to configure the VLAN. For more information about keywords available in this mode, see the
vlan VLAN database configuration command description in the c omma nd r efer en ce f or this re lea se.
When you have finished the configuration, you must enter apply or exit for the configuration to take
effect. When you enter the exit command, it applies all commands and updates the VLAN database. VTP
messages are sent to other switches in the VTP domain, and the privileged EXEC mode prom pt appear s.
Saving VLAN Configuration
The configurations of VLAN IDs 1 to 1005 are always saved in the VLAN database (vlan.da t file). If the
VTP mode is transparent, they are also saved in the switch running conf ig ur ation file. You can enter the
copy running-config startup-config privileged EXEC command to save the configuration in the star tup
configuration file. In a switch stack, the whole stack uses the same vlan.dat file and running
configuration. To display the VLAN configuration, enter the show vlan privileged EXEC command.
