Chapter12 Configuring VLANs Configuring Extended-Range VLANs
This example shows how to create a new extended-range VLAN with all default characteristics, enter
config-vlan mode, and save the new VLAN in the switch startup configuration file:
Switch(config)# vtp mode transparent
Switch(config)# vlan 2000
Switch(config-vlan)# end
Switch# copy running-config startup config
Creating an Extended-Range VLAN with an Internal VLAN ID
If you enter an extended-range VLAN ID that is already assigned to an internal VLAN, an e rror message
is generated, and the extended-range VLAN is rejected. To manually free an internal VLAN ID, you
must temporarily shut down the routed port that is using the internal VLAN ID.
Beginning in privileged EXEC mode, follow these steps to release a VLAN ID that is assigned to an
internal VLAN and to create an extended-range VLAN with that ID:
Command Purpose
Step1 show vlan internal usage Display the VLAN IDs being used internally by the switch. If the VLAN
ID that you want to use is an internal VLAN, the display shows the routed
port that is using the VLAN ID. Enter that port number in Step 3.
Step2 configure terminal Enter global configuration mode.
Step3 interface interface-id Specify the interface ID for the routed port that is using the VLAN ID,
and enter interface configuration mode.
Step4 shutdown Shut down the port to free the internal VLAN ID.
Step5 exit Return to global configuration mode.
Step6 vtp mode transparent Set the VTP mode to transparent for creating extended-range VLANs.
Step7 vlan vlan-id Enter the new extended-range VLAN ID, and enter config-vlan mode.
Step8 exit Exit from config-vlan mode, and return to global configuration mode.
Step9 interface interface-id Specify the interface ID for the routed port that you shut down in Step 4,
and enter interface configuration mode.
Step10 no shutdown Re-enable the routed port. It will be assigned a new internal VL A N ID .
Step11 end Return to privileged EXEC mode.
Step12 copy running-config startup config Save your entries in the switch startup configuration file. To save an
extended-range VLAN configuration, you need to save the VTP
transparent mode configuration and the extended-range VLAN
configuration in the switch startup configuration file. Otherwise, if the
switch resets, it will default to VTP server mode, and the extended-range
VLAN IDs will not be saved.
