Server

Server
VTP server mode is the default for all Catalyst switches. You need at least one server in your VTP
domain to propagate VLAN information throughout the domain. The following must be completed
within server mode:
 Create, add, or delete VLANs on a VTP domain.
 Change VTP information. Any change made to a switch in server mode is advertised to the
entire VTP domain.
Global VLANs must be configured on a server. The server adds the VLANs to the switch
configuration, so every time the switch boots up, the VLAN knowledge is propagated.
