Test results of VTP password setting and Huawei switch vlan configuration

The VTP password settings and Huawei switch vlan configuration experiment results show you how to configure the vlan of a Huawei switch. Many people may not understand the vlan configuration of a Huawei switch, VTP transparent mode, VTP password settings, and V1, v2 integrated application. It doesn't matter. After reading this article, you will certainly have a lot of GAINS. I hope this article will teach you more things.

Verify the effect of VTP password on VTP Protocol
◆ Configure the VTP password of SW3 to 123456, and then add vlan100, vlan200, and vlan300 to sw3.
◆ Check whether the vlan configurations of Huawei Switches of SW3, SW5, and SW6 are consistent. SW3 and SW6 are used as examples.
◆ Set the VTP password of SW5 and SW6 to 123456 to see if the vlan configuration of the Huawei switch of SW3 can be learned. Take SW5 as an example, as shown in:
◆ Test Result: VTP notification can be learned only when the same password as SW3 is configured on SW5 and SW6. Otherwise, the notification will be ignored.

VTP transparent mode, VTP password setting and comprehensive application of V1 and V2

◆ Keep The VTP version of all vswitches V1 and the password unchanged. Then configure the VTP mode of SW5 to the transparent mode transparent ). Check whether SW6 can learn the vlan configuration of the Huawei switch of SW3.

◆ Keep The VTP mode of SW5 transparent and the password remains unchanged. Then, set the VTP version of all vswitches to V2. Check whether SW6 can learn the vlan configuration of the Huawei switch of SW3. Configure SW3 as an Example

◆ Make sure that The VTP mode of SW5 is transparent and that VTP versions of all vswitches are V2. Remove all VTP passwords and check whether SW6 can learn the vlan configuration information of the Huawei switch of sw3.

◆ Make sure that The VTP mode of SW5 is transparent and that VTP versions of all vswitches are V2. Remove all VTP passwords and set the VTP domain name of SW5 to 123.com. check whether SW6 can learn the vlan configuration information of the Huawei switch of SW3.

Test results of vlan configuration for Huawei switches:

◆ Vtp transparent mode SW5) You can forward received vtp notifications without learning vtp information.

◆ After The VTP password is set, The VTP transparent mode is SW5) No VTP notification is forwarded.

◆ In Version1 VTP without a password, a switch in transparent mode does not forward the received VTP notification to check the domain name and version number)

◆ In Version2 VTP without a password, the vswitch domain name in transparent mode may be different from the vtp server.) The forwarded VTP notification does not check the domain name and version number)

Conclusion: The VTP protocol is a proprietary protocol developed by Cisco. by enabling the VTP protocol, the vlan configuration of the Huawei switch can be consistent and error-free, you can also manage the entire vswitch connected to a single vswitch.

As long as the vswitch in vtp server mode is modified, other vswitches connected to the same VTP domain are correctly configured.) You can learn the notifications from vtp server switches, this ensures the consistency of vlan configurations of Huawei switches.
