vtp (global configuration) Chapter 2 Catalyst 3560 Switch Cisco IOS Commands Follow these guidelines when setting VTP mode: • The no vtp mode command returns the switch to VTP server mode. • The vtp mode server command is the same as no vtp mode except that it does not return an error if the switch is not in client or transparent mode. • If the receiving switch is in client mode, the client switch changes its configuration to duplicate the configuration of the server. If you have switches in client mode, be sure to make all VTP or VLAN configuration changes on a switch in server mode. If the receiving switch is in server mode or transparent mode, the switch configuration is not changed. • Switches in transparent mode do not participate in VTP. If you make VTP or VLAN configuration changes on a switch in transparent mode, the changes are not propagated to other switches in the network. • If you change the VTP or VLAN configuration on a switch that is in server mode, that change is propagated to all the switches in the same VTP domain. • The vtp mode transparent command disables VTP from the domain but does not remove the domain from the switch. • The VTP mode must be transparent for you to add extended-range VLANs or for VTP and VLAN information to be saved in the running configuration file. • If extended-range VLANs are configured on the switch and you attempt to set the VTP mode to server or client, you receive an error message, and the configuration is not allowed. • VTP can be set to either server or client mode only when dynamic VLAN creation is disabled. Follow these guidelines when setting a VTP password: • Passwords are case sensitive. Passwords should match on all switches in the same domain. • When you use the no vtp password form of the command, the switch returns to the no-password state. Follow these guidelines when setting VTP pruning: • VTP pruning removes information about each pruning-eligible VLAN from VTP updates if there are no stations belonging to that VLAN. • If you enable pruning on the VTP server, it is enabled for the entire management domain for VLAN IDs 1 to 1005. • Only VLANs in the pruning-eligible list can be pruned. • Pruning is supported with VTP Version 1 and Version 2. Follow these guidelines when setting the VTP version: • Toggling the Version 2 (v2) mode state modifies parameters of certain default VLANs. • Each VTP switch automatically detects the capabilities of all the other VTP devices. To use Version 2, all VTP switches in the network must support Version 2; otherwise, you must configure them to operate in VTP Version 1 mode. • If all switches in a domain are VTP Version 2-capable, you need only to configure Version 2 on one switch; the version number is then propagated to the other Version-2 capable switches in the VTP domain. • If you are using VTP in a Token Ring environment, VTP Version 2 must be enabled. 2-696 Catalyst 3560 Switch Command Reference 78-16405-05
