Setting the Default VLAN

 

 

 

 

 

PVID—When this option in selected, the port uses the selected VLAN ID as its port VLAN ID (PVID). The port assigns the PVID to all untagged frames received on the port before forwarding. The following configuration rules apply:

-If the interface VLAN mode is General, any VLAN of which the interface is a Tagged or Untagged member can be selected to provide the PVID.

-If the interface VLAN mode is Trunk, the PVID is set to the VLAN ID of which the port is a tagged member.

-If the interface VLAN type is Access, the PVID is set to the Access VLAN ID and this field cannot be modified.

When you select the Untagged, Tagged, and PVID options and move the VLAN to the Selected list, a U, T, and/or P is appended to the VID.

STEP 4 Click Apply and then click Close. Your changes are saved to the Running Configuration.

Setting the Default VLAN

By default, the switch automatically creates VLAN 1 as the default VLAN for all ports and link aggregation groups (LAGs). If a port has no VLAN memberships, the switch automatically configures it as a member of the default VLAN.

You can use the Default VLAN Settings page to change the default VLAN.

When the VID of the default VLAN is changed:

Ports that were members of the original default VLAN are removed as members of that VLAN and are configured as members of the new default VLAN.

The Port VLAN Identifier (PVID) of the ports that were members of the original default VLAN is changed to the VID of the new default VLAN.

If the management VLAN was the same as the original default VLAN, then the management VLAN is updated to the new default VLAN provided there is at least one member port. If DHCP is enabled, the switch attempts to renew the switch IP address through DHCP.

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.
