Configuring VLAN Interface Settings

 

 

 

 

 

Frame Type—Specifies the frame type accepted on the port:

-Admit Untagged Only—Only untagged frames are accepted on the port. Tagged frames are discarded.

-Admit Tagged Only—Only tagged frames are accepted on the port. Untagged frames are discarded.

-Admit All—Both tagged and untagged frames are accepted on the port.

An access port can admit untagged frames only. A trunk port can be assigned to only one untagged VLAN, called the native VLAN and, can be assigned to any number of tagged VLANs (or none). If a trunk port is member of both untagged and tagged VLANs, it admits all frame types. If the trunk port is member of tagged VLANs only, it admits tagged frames only.

Ingress Filtering—Select to enable ingress filtering on the port. When ingress filtering is enabled, the switch accepts frames only from the VLANs of which it is a member. It discards frames received from other VLANs. All ports in access or trunk mode will always have their Ingress Filtering enabled. Disabling and enabling Ingress Filtering is only available on ports set to General Mode.

VLAN Priority—The default 802.1p priority value for the port. The value will be applied to the incoming packets based on the QoS trust mode configured at the port and the types of the packets. See QoS Properties for information and instructions on configuring the port trust mode.

STEP 3 Click Apply and then click Close. Your changes are saved to the Running Configuration.

Changing the Interface VLAN Mode

When the interface VLAN mode of a port is changed, the switch automatically handles the affected VLAN membership configuration, as follows:

Changing from Access Port to Trunk Port

The VLAN configuration remains unchanged. The Access port VLAN becomes the native VLAN for the Trunk port. The port must follow the restrictions for Trunk ports.

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.
