Does a VTPv3 client maintain its VLAN database in NVRAM?

A VTPv3 (VLAN Trunking Protocol version 3) client does not maintain its VLAN database in NVRAM. Instead, it dynamically receives its VLAN information from the VTP server within the same domain. VTP is used primarily to manage VLAN configurations across multiple switches, allowing for changes made on a VTP server to propagate and be updated across all VTP clients.

Client switches in a VTP environment rely on the server for VLAN information, which is stored centrally on the server switch. Therefore, upon a reboot, the VTP client would not retrieve VLAN information from its own NVRAM but rather from the VTP server. Any VLAN configurations on a VTP client are transient and do not persist after a reboot unless that client is in transparent mode.

Understanding this functionality is crucial for network management and troubleshooting since any VLAN changes or configurations made on a client switch will not be retained if the switch is powered down or restarted, leading to potential network connectivity issues if not properly managed.
