Enabling VTP Version 2
VTP version 2 is disabled by default on VTP version 2-capable switches. When
you enable VTP version 2 on a switch, every VTP version 2-capable switch in the
VTP domain enables version 2.
Caution VTP version 1 and VTP version 2 are not interoperable on switches in the
same VTP domain. Every switch in the VTP domain must use the same VTP
version. Do not enable VTP version 2 unless every switch in the VTP domain
supports version 2.
Note In a Token Ring environment, you must enable VTP version 2 for Token Ring
VLAN switching to function properly.
For more information on VTP version configuration guidelines, see the “VTP
Versio n” section on page 8-19.
