Creating An Extended-Range Vlan - Cisco Catalyst 2960 series Configuration Manual

How to Configure Extended-Range VLANs
a greater number of customers. The extended-range VLAN IDs are allowed for any switchport commands
that allow VLAN IDs.
With VTP version 1 or 2, extended-range VLAN configurations are not stored in the VLAN database, but
because VTP mode is transparent, they are stored in the switch running configuration file, and you can save
the configuration in the startup configuration file by using the copy running-config startup-config privileged
EXEC command. Extended-range VLANs created in VTP version 3 are stored in the VLAN database.

Creating an Extended-Range VLAN

You create an extended-range VLAN in global configuration mode by entering the vlan global configuration
command with a VLAN ID from 1006 to 4094. The extended-range VLAN has the default Ethernet VLAN
characteristics and the MTU size, and RSPAN configuration are the only parameters you can change. See the
description of the vlan global configuration command in the command reference for the default settings of
all parameters. In VTP version 1 or 2, if you enter an extended-range VLAN ID when the switch is not in
VTP transparent mode, an error message is generated when you exit VLAN configuration mode, and the
extended-range VLAN is not created.
In VTP version 1 and 2, extended-range VLANs are not saved in the VLAN database; they are saved in the
switch running configuration file. You can save the extended-range VLAN configuration in the switch startup
configuration file by using the copy running-config startup-config privileged EXEC command. VTP version
3 saves extended-range VLANs in the VLAN database.
