Configuring VLANs in the VTP Database

You use the CLI vlan database VLAN database command to add, change, and delete VLANs. In VTP
server or transparent mode, commands to add, change, and delete VLANs are written to the file vlan.dat,
and you can display them by entering the privileged EXEC show vlan command. The vlan.dat file is
stored in nonvolatile memory. The vlan.dat file is upgraded automatically, but you cannot return to an
earlier version of Cisco IOS after you upgrade to this release.
You can cause inconsistency in the VLAN database if you attempt to manually delete the vlan.dat file.
Caution
If you want to modify the VLAN configuration or VTP, use the VLAN database commands described in
the switch command reference.
You use the interface configuration command mode to define the port membership mode and add and
remove ports from VLANs. The results of these commands are written to the running-configuration file,
and you can display the file by entering the privileged EXEC show running-config command.
Note VLANs can be configured to support a number of parameters that are not discussed in detail in this
section. For complete information on the commands and parameters that control VLAN configuration,
refer to the switch command reference.
