Configuring VTP

VTP and Switch Stacks

VTP configuration is the same in all members of a switch stack. When the switch stack is in VTP server or client mode, all switches in the stack carry the same VTP configuration. When VTP mode is transparent, the stack is not taking part in VTP.

•When a switch joins the stack, it inherits the VTP and VLAN properties of the stack master.

•All VTP updates are carried across the stack.

•When VTP mode is changed in a switch in the stack, the other switches in the stack also change VTP mode, and the switch VLAN database remains consistent.

VTP version 3 functions the same on a standalone switch or a stack except when the switch stack is the primary server for the VTP database. In this case, the MAC address of the stack master is used as the primary server ID. If the master switch reloads or is powered off, a new stack master is elected.

•If you do not configure the persistent MAC address feature (by entering the stack-mac persistent timer [0 time-value] global configuration command, when the new master is elected, it sends a takeover message with the new master MAC address as the primary server.

•If persistent MAC address is configured, the new master waits for the configured stack-mac persistent timer value. If the previous master switch does not rejoin the stack during this time, then the new master issues the takeover message.

VTP Configuration Guidelines

Configuration Requirements

When you configure VTP, you must configure a trunk port so that the switch can send and receive VTP advertisements to and from other switches in the domain.

If you are configuring VTP on a cluster member switch to a VLAN, use the rcommand privileged EXEC command to log in to the member switch. For more information about the command, see the command reference for this release.

In VTP versions 1 and 2, when you configure extended-range VLANs on the switch, the switch must be in VTP transparent mode. VTP version 3 also supports creating extended-range VLANs in client or server mode.

VTP versions 1 and 2 do not support private VLANs. VTP version 3 does support private VLANs. If you configure private VLANs, the switch must be in VTP transparent mode. When private VLANs are configured on the switch, do not change the VTP mode from transparent to client or server mode.

VTP Settings

The VTP information is saved in the VTP VLAN database. When VTP mode is transparent, the VTP domain name and mode are also saved in the switch running configuration file, and you can save it in the switch
