Configuring VLAN Interface Settings

 

 

 

 

 

Changing from Trunk Port to Access Port

If the original trunk port has an untagged VLAN member on the port, the port is removed from all its VLANs except the untagged VLAN on the port. The PVID is set to the untagged VLAN ID.

If the original Trunk port does not have an untagged VLAN member on the port, the port is removed from all its VLANs and becomes a member of the default VLAN. Its PVID is set to the default VLAN ID and the port is set to admit only untagged or priority-tagged packets. The port is untagged for the default VLAN.

Changing from Access Port to General Port

The VLAN configuration remains unchanged except that the port can now admit all frames. As a General port, it can be a tagged or an untagged member of any VLAN.

Changing from General Port to Access Port

If the General port has no untagged VLAN membership that provides the PVID for the port, when the port is changed to an Access port it is removed from all the General port's VLANs and becomes an untagged member of the default VLAN. The Access port PVID is set to the default VLAN.

The Access port admits only untagged or priority-tagged packets.

Changing from Trunk Port to General Port

The VLAN configuration remains unchanged. As a General port, the port can be a tagged or an untagged member of any VLAN.

Changing from General Port to Trunk Port

The VLAN configuration remains unchanged. The PVID of the General port is used to configure the native VLAN of the Trunk port. The port must follow the restrictions of the Trunk port.

For example, assume a General port is an untagged member of VLANs 1, 10, and 20, and the port’s PVID is 1.

When the port is changed to a Trunk port, VLAN 1 becomes the native VLAN. The Trunk port remains a member of VLANs 10 and 20, but now with tagging enabled.

Deleting a VLAN

When a VLAN is deleted, the following actions occur:

If the deleted VLAN was a Trunk port’s native VLAN, the trunk port’s native VLAN and PVID are changed to the default VLAN.

SLM2008PTNA specifications

Cisco Systems SLM2008PTNA is a robust network switch designed specifically for small to medium-sized businesses. It operates with 8 Fast Ethernet ports, providing advanced features and best-in-class performance to enhance your network infrastructure. This model ensures seamless connectivity for multiple devices, making it an ideal choice for environments requiring reliable network communication.

One of the standout features of the SLM2008PTNA is its Layer 2 switching capabilities. This switch supports auto-negotiation, which allows each port to automatically detect the speed of the connected device and adjust accordingly. This ensures optimal performance and smooth operation across various connected devices. Additionally, the switch supports a non-blocking architecture, ensuring that bandwidth is not shared, which significantly enhances data transmission speed.

Power over Ethernet (PoE) is another key technology incorporated into the Cisco SLM2008PTNA. It simplifies the installation of network devices such as VoIP phones, security cameras, and wireless access points by supplying power through the Ethernet cable. This eliminates the need for separate power sources, reducing installation costs and increasing flexibility in device placement.

Moreover, the SLM2008PTNA comes equipped with advanced security features, such as port security and VLAN support. Port security allows network administrators to restrict access to the network based on MAC addresses, preventing unauthorized access and enhancing network security. The support for Virtual Local Area Networks (VLANs) enables the segmentation of the network into different logical networks, improving traffic management and security within each segment.

The switch is designed for easy management and monitoring, featuring a user-friendly web interface that simplifies configuration. This allows network administrators to quickly set up and manage the device without requiring extensive technical knowledge. Additionally, its compact design makes it suitable for desktop or rack-mount installation, maximizing space efficiency in network environments.

In conclusion, the Cisco Systems SLM2008PTNA is an essential component for small to medium-sized businesses looking to enhance their network performance. With its Layer 2 switching capabilities, Power over Ethernet support, advanced security features, and ease of management, this switch provides a well-rounded solution for modern networking needs, delivering reliable performance and scalability for growth.
