The Foundation Summary is a collection of information that provides a convenient review of many key concepts in this chapter. If you are already comfortable with the topics in this chapter, this summary can help you recall a few details. If you just read this chapter, this review should help solidify some key facts. If you are doing your final preparation before the exam, this information is a convenient way to review the day before the exam.

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.)
