Table 7-3. Catalyst VTP Modes

VTP Mode

Characteristics

Server

All VLAN and VTP configuration changes occur here. The server advertises settings and changes to all other servers and clients in a VTP domain. (This is the default mode for Catalyst switches.)

Client

Listens to all VTP advertisements from servers in a VTP domain. Advertisements are relayed out other trunk links. No VLAN or VTP configuration changes can be made on a client.

Transparent

VLAN configuration changes are made locally, independent of any VTP domain. VTP advertisements are not received but merely are relayed out other trunk links, if possible.


Table 7-4. Types of VTP Advertisements

AdvertisementType

Function

Summary

Sent by server every 300 seconds and after a topology change. Contains a complete dump of all VTP domain information.

Subset

Sent by server only after a VLAN configuration change. Contains only information about the specific VLAN change.

Advertisement request

Sent by client when additional VTP information is needed. Servers sent summary or subset advertisements in response.

Pruning request

Sent by clients and servers to announce VLANs that are in active use on local switch ports. These VLANs should not be pruned by neighbors. (These messages are destined for nearest-neighbor switches and are not relayed throughout the domain.)
