Purpose
Enter the new extended-range VLAN ID, and enter VLAN configuration
mode.
Exit from VLAN configuration mode, and return to global configuration
mode.
Specify the interface ID for the routed port that you shut down in Step 4,
and enter interface configuration mode.
Re-enable the routed port. It will be assigned a new internal VLAN ID.
Return to privileged EXEC mode.
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.

This step is not required for VTP version 3 because VLANs are
saved in the VLAN database.
Purpose
Display characteristics for all interfaces or for
the specified VLAN configured on the switch.
Display parameters for all VLANs or the
specified VLAN on the switch.
