Chapter 14 Configuring VLANs
Configuring Extended-Range VLANs
Beginning in privileged EXEC mode, follow these steps to create an extended-range VLAN:
To delete an extended-range VLAN, use the no vlan vlan-id global configuration command.
The procedure for assigning static-access ports to an extended-range VLAN is the same as for
normal-range VLANs. See the “Assigning Static-Access Ports to a VLAN” section on page 14-9.
This example shows how to create a new extended-range VLAN with all default characteristics, enter
VLAN configuration 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 error 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.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 vtp mode transparent Configure the switch for VTP transparent mode, disabling VTP.
Note This step is not required for VTP version 3.
Step 3 vlan vlan-id Enter an extended-range VLAN ID and enter VLAN configuration mode.
The range is 1006 to 4094.
Step 4 mtu mtu-size (Optional) Modify the VLAN by changing the MTU size.
Note Although all VLAN commands appear in the CLI h elp, only the
mtu mtu-size, private-vlan, and remote-span commands are
supported for extended-range VLANs.
Step 5 remote-span (Optional) Configure the VLAN as the RSPAN VLAN. See the
“Configuring a VLAN as an RSPAN VLAN” section on page 28-16.
Step 6 end Return to privileged EXEC mode.
Step 7 show vlan id vlan-id Verify that the VLAN has been created.
Step 8 copy running-config startup config Save your entries in the switch startup configuration file. To save
extended-range VLAN configurations, 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.
Note With VTP version 3, the VLAN configuration is also saved in the
VLAN database.
