How to set vlanid

Method to set vlanid: 1. VLAN ID setting of switch; 2. VLAN ID setting of router; 3. VLAN ID configuration example. Detailed introduction: 1. VLAN ID setting of the switch. Log in to the switch management interface, enter the VLAN configuration page, select the VLAN that needs to be configured, and set the VLAN ID. Set other parameters of the VLAN as needed, such as name, port members, etc., and save the settings. And apply the configuration; 2. Set the VLAN ID of the router, log in to the router management interface, etc.

VLAN (Virtual LAN) is a technology that divides a physical LAN into multiple logically independent virtual networks. The setting and configuration of VLAN plays an important role in network management, which can provide better network performance and security. This article will introduce how to set VLAN ID to help readers better understand and configure VLAN.

Part 1: Overview of VLAN ID

1.1 What is VLAN ID

VLAN ID refers to the unique identifier of the VLAN, which is used to identify and distinguish different VLANs. Each VLAN has a unique VLAN ID, usually a 12-digit number.

1.2 The function of VLAN ID

The main function of VLAN ID is to divide different devices and users into different VLANs to achieve logical isolation and segmentation. Through the setting of VLAN ID, the performance, security and management efficiency of the network can be improved.

Part 2: How to set VLAN ID

2.1 VLAN ID setting of switch

Most switches support VLAN ID setting, specifically The method is as follows:

1) Log in to the switch management interface and enter the VLAN configuration page.

2) Select the VLAN to be configured and set the VLAN ID.

3) Set other parameters of VLAN according to requirements, such as name, port members, etc.

4) Save the settings and apply the configuration.

2.2 Router’s VLAN ID setting

The router can also configure the VLAN ID. The specific method is as follows:

1) Log in to the router management interface and enter the VLAN configuration page.

2) Select the VLAN to be configured and set the VLAN ID.

3) Set other parameters of VLAN according to needs, such as IP address, subnet mask, etc.

4) Save the settings and apply the configuration.

2.3 VLAN ID configuration example

Assume we have a network environment that contains three VLANs, namely VLAN 10, VLAN 20 and VLAN 30. We can configure it according to the following steps:

1) Log in to the switch management interface and enter the VLAN configuration page.

2) Select VLAN 10 and set VLAN ID to 10.

3) Select VLAN 20 and set VLAN ID to 20.

4) Select VLAN 30 and set VLAN ID to 30.

5) Set other parameters of each VLAN according to requirements, such as name, port members, etc.

6) Log in to the router management interface and enter the VLAN configuration page.

7) Select VLAN 10 and set VLAN ID to 10.

8) Select VLAN 20 and set VLAN ID to 20.

9) Select VLAN 30 and set VLAN ID to 30.

10) Set other parameters of each VLAN according to requirements, such as IP address, subnet mask, etc.

11) Save the settings and apply the configuration.

Part 3: Common problems and solutions of VLAN ID

3.1 VLAN ID conflict problem

When different devices or switches are configured with the same When using different VLAN IDs, VLAN ID conflicts will occur, thus affecting the normal operation of the network. The solution is to check and modify duplicate VLAN IDs to ensure that each VLAN has a unique VLAN ID.

3.2 VLAN ID range issue

The range of VLAN ID is usually from 1 to 4094, but not all VLAN IDs are available. Some VLAN IDs have been reserved, such as VLAN 1 is generally used for the default VLAN, VLAN 1002-1005 is used for specific protocols such as FDDI and Token Ring. The workaround is to avoid using reserved IDs when selecting VLAN IDs.

3.3 VLAN ID configuration issues

When configuring the VLAN ID, incorrect settings or omissions may occur. The solution is to carefully check and confirm the configuration of each VLAN to ensure that the VLAN ID and other parameters are set correctly.

Conclusion:

The setting and configuration of VLAN ID is an important step in building a virtual LAN, which can provide better network performance and security. When setting VLAN IDs, you need to pay attention to avoid conflicts and range issues, and carefully check the accuracy of the configuration. By correctly setting and configuring VLAN ID, we can better manage and maintain the network environment and improve network efficiency and reliability.
