Analysis and examples of vtp protocol (1)

In the use of vswitches, we need to pay attention to the use of the VTP protocol. Next we will analyze the vlan settings. Among them, the use of VTP is a key. I hope you can master it. The specific objectives are as follows:

Verify VTP protocol principles

Experimental principle: VTP is a message protocol that uses Layer 2 frames to manage the addition, deletion, and rename of vlan configurations of Huawei switches on the basis of the entire network, to ensure the consistency of vlan configurations of Huawei switches. With VTP, you can modify the vlan configuration of a Huawei switch on one vswitch. The changes will be automatically transmitted to all other computers in the network.

Test topology:

 

Huawei switch vlan configuration

Test procedure for vlan configuration of a Huawei switch:

◆ Set SW3 to server mode, and SW5 and SW6 to client mode. Verify that SW5 and SW6 can learn the vlan configuration information of the Huawei switch of SW3.

◆ Configure port F0/23 of SW3, port F0/23 of SW5, port F0/24 of SW3, and port F0/24 of SW6 to trunk mode. The relay mode must be enabled between switches.

◆ Set the VTP domain name of SW3 to benet.com, and set its mode to server) mode, enable the default value of version 1 ), enabling VTP trim can reduce unnecessary broadcast information on the relay port ).
