Secondary VTP server configuration

[sachin_mon]

Hi,

1.We are having a 6513 switch currently acting as VTP server.We are having a secondary 6513 switch which we want to configure as secondary vtp server.I wanted to know whether we require any downtime for configuring the secondary vtp server.Will there be any flapping in the network..?

Sachin,

Just make sure the VTP configuration revision # on the new switch is lower than that of the existing VTP server switch, enter the VTP configuration - VTP mode as server, domain name, password etc - set up the trunk and the new switch would dynamically learn all the VLANs from the existing VTP server. If you do it this way no downtime would be required and there should be no disruption to production traffic.

Have a look at this document to learn more about VTP configuration revision.
