vlan (global configuration)

Use the vlan global configuration command to add a VLAN and enter the config-vlan mode. Use the no

form of this command to delete the VLAN. Configuration information for normal-range VLANs (VLAN

IDs 1 to 1005) is always saved in the VLAN database. When VLAN Trunking Protocol (VTP) mode is

transparent, you can create extended-range VLANs (VLAN IDs greater than 1005), and the VTP mode

and domain name and the VLAN configuration are saved in the switch running configuration file. You

can save configurations in the switch startup configuration file by entering the copy running-config

startup-config privileged EXEC command.

Command History

Usage Guidelines You must use the vlan vlan-id global configuration command to add extended-range VLANs (VLAN IDs

1006 to 4094). Before configuring VLANs in the extended range, you must use the vtp transparent

global configuration or VLAN configuration command to put the switch in VTP transparent mode.

Extended-range VLANs are not learned by VTP and are not added to the VLAN database, but when VTP

mode is transparent, VTP mode and domain name and all VLAN configurations are saved in the running

configuration, and you can save them in the switch startup configuration file.

vlan-id ID of the VLAN to be added and configured. For vlan-id, the range is 1 to 4094 when

the enhanced software image (EI) is installed and 1 to 1005 when the standard

software image (SI) is installed; do not enter leading zeros. You can enter a single

VLAN ID, a series of VLAN IDs separated by commas, or a range of VLAN IDs

separated by hyphens.
