How to Configure Extended-Range VLANs
WithVTP version 1 and version 2, when the switch is in VTP transparent mode (VTP disabled), you can
createextended-range VLANs (in therange 1006to 4094).VTP 3version supportsextended-range VLANs
inserver ortransparent move.
Extended-rangeVLANs enable service providers to extend their infrastructure to a greater number of customers.
Theextended-range VLAN IDsare allowedfor any switchportcommands that allow VLAN IDs.
WithVTP version 1 or 2, extended-range VLAN configurations are not stored in the VLAN database, but
becauseVTP mode is transparent, they are stored in the switch running configuration file, and you can save
theconfiguration in the startup configuration file. Extended-range VLANs created in VTP version 3 are stored
inthe VLAN database.
Youcan change only the MTU size, private VLAN, and the remote SPANconfiguration state on extended-range
VLANs;all other characteristicsmust remain at the default state.

Creating an Extended-Range VLAN

Youcreate an extended-range VLAN in global configuration mode by entering the vlan global configuration
commandwith a VLAN ID from 1006 to 4094. Theextended-range VLAN has the default Ethernet VLAN
characteristicsand the MTU size, and RSPAN configuration are the only parameters you can change. See the
descriptionof the vlanglobal configuration command in thecommand reference for thedefault settings of
allparameters. In VTP version 1 or 2, if you enter an extended-range VLAN ID when the switch is not in
VTPtransparent mode, an error message is generated when you exit VLAN configuration mode, and the
extended-rangeVLAN is notcreated.
InVTP version 1 and 2, extended-rangeVLANs are not saved in the VLAN database; they are saved in the
switchrunning configuration file. You can save the extended-range VLAN configuration in the switch startup
configurationfile by using the copy running-config startup-config privileged EXEC command. VTP version
3saves extended-rangeVLANs in theVLAN database.
Beforeyou create an extended-range VLAN, you can verify that the VLAN ID is not used internally by
enteringthe show vlaninternal usage privilegedEXEC command. If theVLAN ID isused internally
andyou want to free it up, go to the Creating an Extended-Range VLAN with an Internal VLAN ID before
creatingthe extended-range VLAN.
