Does a VTP transparent mode maintain its VLAN database in NVRAM?

In a VTP (VLAN Trunking Protocol) transparent mode, the switch does maintain its VLAN database in NVRAM (Non-Volatile Random Access Memory). Unlike switches operating in server or client mode, which share VLAN information within a VTP domain, a switch in transparent mode does not participate in the VTP domain. Instead, it retains a locally configured VLAN database that is saved in NVRAM.

This means that all VLAN configurations created on a switch in transparent mode are stored and preserved, even after reboots or power cycles. The switch will keep its VLAN configurations regardless of the VTP advertisements it receives. It acts independently of other switches in a VTP domain and allows for specific VLAN setups unique to that transparent switch.

This behavior is crucial for network designs that require specific VLAN configurations on certain switches without the interference of VTP updates from the configuration of other switches within the overall switching environment. This ensures that the switch can still function correctly in the presence of a larger VTP domain while maintaining its own VLAN settings securely.
