When the root bridge is selected and each root port is established, each network segment can then determine which bridge provides the lowest cost path to the root port. The port that provides this path is named the designated port for the network segment. Spanning tree disables other ports for that network segment or designates them as alternate or backup ports.

Supported spanning tree versions include Common Spanning Tree (CST) and

Rapid STP (RSTP). This switch does not support Multiple STP (MSTP).

CST (IEEE 802.1D) is the original protocol version that provides a single path between end stations, avoiding and eliminating loops.

RSTP (IEEE 802.1D-2004 or IEEE 802.1w) provides protocol enhancements that enable a network to more quickly achieve an optimal STP topology. Spanning tree is enabled by default and set to be RSTP.

Configuring STP Status and Global Settings

You can use the STP Status & Global Settings page to enable STP, select the STP mode of operation, and configure bridge priority settings. You can also view status information about the STP topology. To display this page, click Spanning Tree > STP Status & Global Settings in the navigation window.

This page enables you to configure global settings and bridge settings, and displays information about the designated root.

Configuring Global and Bridge Settings

To configure STP global settings and bridge settings:

STEP 1 Specify the following global settings:

Spanning Tree State—Select to enable STP operation on the switch. You must also enable STP operation on individual ports (see Configuring STP Interface Settings).

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.
