What does the Access port do?

The role of the Access port: 1. Connecting terminal devices: The Access port is used to connect terminal devices, such as computers, IP phones, etc.; 2. Provide access to a single VLAN: Access ports are usually configured to belong to a specific VLAN; 3. Implement VLAN isolation: By configuring the Access port as a specific VLAN, isolation between VLANs can be achieved; 4. Control the broadcast domain: the Access port can limit the scope of the broadcast domain; 5. Simplify configuration management, etc.

The Access port has the following main functions in the switch:

1. Connecting terminal devices: The Access port is used to Connect terminal equipment, such as computers, IP phones, etc. Through the Access port, the terminal device can access the LAN and communicate with other devices.

2. Provide access to a single VLAN: Access ports are usually configured to belong to a specific VLAN. This means that the data frames transmitted through the Access port only belong to this VLAN and will not span different VLANs.

3. Implement VLAN isolation: By configuring the Access port as a specific VLAN, isolation between VLANs can be achieved. Different Access ports can be connected to different VLANs to ensure that data between different VLANs will not interfere with each other.

4. Control broadcast domain: Access port can limit the scope of broadcast domain. By connecting end devices to different VLANs, you can reduce the propagation range of broadcast traffic and improve network performance and security.

5. Simplified configuration management: By using the Access port, the configuration and management of terminal devices can be separated from the configuration and management of other VLANs, simplifying network configuration and management.

It should be noted that the Access port can only transmit data belonging to the specified VLAN and does not support transmitting data of multiple VLANs. If you need to transmit data of multiple VLANs between switches, you need to use Trunk ports. Therefore, based on network requirements and design, proper configuration and use of Access ports can provide flexible VLAN isolation and the ability to control broadcast domains.
