VTP client mode

Q: How deeply does Acing the CCNA Exam: Volume 1 Fundamentals and Protocols cover VTP client mode?

Explains synchronization behavior, configuration syntax, and rejected CLI input without detailing VTP internals.

As explained in Acing the CCNA Exam: Volume 1 Fundamentals and Protocols

VTP client mode is a VTP operating mode in which a switch cannot modify VLANs but receives and synchronizes VLAN database advertisements.

VTP client mode lets a switch receive and synchronize VLAN database advertisements, but prevents it from creating, modifying, or deleting VLANs locally. section 13.2.2

A VTP client:

Synchronizes its VLAN database with VTP server or client switches in the domain. section 13.2.2
Rejects local VLAN creation, modification, and deletion commands. section 13.2.2
Uses vtp mode client for configuration; server mode remains the default. section 13.3

Rejected VLAN configuration

SW3(config)# vtp mode client SW3(config)# vlan 5 VTP VLAN configuration not allowed when device is in CLIENT mode. The mode command succeeds, but the VLAN command is rejected.

Table 13.3 VTP modes (view table figure)

Mode	Description
Server	This is the default mode. The switch can create/modify/delete VLANs. It will advertise changes to its VLAN database and synchronize its VLAN database upon receiving an advertisement with a higher revision number.
Client	The switch cannot create/modify/delete VLANs but otherwise behaves the same as a server.
Transparent	The switch can create/modify/delete VLANs, but it will not advertise changes to its own VLAN database and will not synchronize its VLAN database with others. The switch does not directly participate in the VTP domain, but it will forward VTP messages between switches in the same domain.
Off	The switch can create/modify/delete VLANs, but it will not advertise changes to its own VLAN database and will not synchronize its VLAN database with others. The switch does not participate in VTP at all.

Compare client mode with server, transparent, and off modes. section 13.2.2
