RSTP Interface Settings

 

 

 

 

 

By default, the RSTP Interface Settings Table displays information for each port.

Use the Interface Type list to display ports or LAGs in the table. The RSTP

Interface Table displays the following information for each port:

•Point to Point Operational Status—A physical port has a point-to-point connection to a LAN if it operates in full duplex.

•Port Role—Port role assigned by the STP algorithm to provide to STP paths. The possible field values are:

-Root—Provides the lowest root path cost to the root bridge among all the ports in the switch.

-Designated—Provides the lowest root path cost to the root bridge from a LAN. The switch is the designated bridge in the LAN.

-Alternate—Provides an alternate path to the root bridge from the root interface.

-Backup—Provides a backup path to the designated port path toward the Spanning Tree leaves. Backup ports occur only when two ports are connected in a loop by a point-to-point link, or when a LAN has two or more connections connected to a shared segment.

-Disabled—The port is not participating in the Spanning Tree.

•Mode—Indicates whether the RSTP administrative mode is enabled or disabled for the port.

•Edge Port Operational Status—If enabled for the port or LAG, the port is automatically placed in the forwarding state. See Configuring STP Interface Settings for instructions on modifying this setting.

•Port Status—The operational state of the port.

You can select a port and click Activate Protocol Migration to have the switch send RSTP BPDUs to the port. This can be used to test whether all legacy bridges on the LAN have been removed.

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.
