Default Vtp Configuration - Cisco Catalyst 2960 series Configuration Manual

VTP Configuration Guidelines
Note
• VTP version 3 supports extended-range VLANs. If extended VLANs are configured, you cannot convert
from VTP version 3 to VTP version 2.
• If you configure the switch for VTP client mode, the switch does not create the VLAN database file
(vlan.dat). If the switch is then powered off, it resets the VTP configuration to the default. To keep the
VTP configuration with VTP client mode after the switch restarts, you must first configure the VTP
domain name before the VTP mode.

For VTP version 1 and 2, before you create extended-range VLANs (VLAN IDs 1006
to 4094), you must set VTP mode to transparent by using the vtp mode transparent
global configuration command. Save this configuration to the startup configuration so
that the switch starts in VTP transparent mode. Otherwise, you lose the extended-range
VLAN configuration if the switch resets and boots up in VTP server mode (the default).
If all switches are operating in VTP client mode, do not configure a VTP domain name.
If you do, it is impossible to make changes to the VLAN configuration of that domain.
Therefore, make sure you configure at least one switch as a VTP server.
