Which two commands can be used to verify successful VTP operation between switches?

To verify successful VTP (VLAN Trunking Protocol) operation between switches, the command that provides detailed information about the current status of VTP is the first one. The "show vtp status" command displays critical information such as the VTP domain name, VTP mode (client, server, or transparent), and the revision number. It also allows you to determine whether the VTP advertisements are being sent and received properly. These insights help in diagnosing any VTP-related issues and ensuring that the switches are synchronized in terms of VLAN information.

Although related commands exist, they serve different purposes or focus on specific aspects of the configuration. For instance, while "show vlan" provides details about the configured VLANs on a switch, it does not directly indicate VTP status or operational efficiency. Similarly, "show interface trunk" shows information about trunk links and the VLANs allowed on those trunks but does not provide a complete perspective on VTP operation specifically. Lastly, "show vtp configuration," while informative regarding how VTP is set up, may not offer the comprehensive operational status that "show vtp status" does.

Thus, the first command is the most pertinent when it comes to verifying the overall functionality of VTP across switches.
