VTP Version 1 and Version 2 Configuration Guidelines Chapter 9 Configuring VTP VTP Version 1 and Version 2 Configuration Guidelines This section describes the guidelines for implementing VTP in your network: • All switches in a VTP domain must run the same VTP version. • You must configure a password on each switch in the management domain when in secure mode. Caution If you configure VTP in secure mode, the management domain will not function properly if you do not assign a management domain password to each switch in the domain. • A VTP version 2-capable switch can operate in the same VTP domain as a switch running VTP version 1 provided that VTP version 2 is disabled on the VTP version 2-capable switch (VTP version 2 is disabled by default). • Do not enable VTP version 2 on a switch unless all of the switches in the same VTP domain are version 2 capable. When you enable VTP version 2 on a switch, all of the version 2-capable switches in the domain enable VTP version 2. • Enabling or disabling VTP pruning on a VTP server enables or disables VTP pruning for the entire management domain. • Making VLANs pruning eligible or pruning ineligible on a switch affects pruning eligibility for those VLANs on that device only (not on all switches in the VTP domain). • With software release 8.1(1), all VTP versions can be configured on a per-port basis. See the "VTP Version 3 Per-Port Configuration" section on page 9-14. Configuring VTP Version 1 and Version 2 These sections describe how to configure VTP: • Configuring a VTP Server, page 9-7 • Configuring a VTP Client, page 9-7 • Configuring VTP (VTP Transparent Mode), page 9-8 • Disabling VTP Using the Off Mode, page 9-9 • Enabling VTP Version 2, page 9-9 • Disabling VTP Version 2, page 9-10 • Enabling VTP Pruning, page 9-11 • Disabling VTP Pruning, page 9-12 • Displaying VTP Statistics, page 9-12 Catalyst 4500 Series, Catalyst 2948G, Catalyst 2980G Switches Software Configuration Guide-Release 8.1 9-6 78-15486-01
