Spanning Tree Commands 4

spanning-tree portfast

This command sets an interface to fast forwarding. Use the no form to disable fast forwarding.

Syntax

[no] spanning-tree portfast

Default Setting

Disabled

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

•This command is used to enable/disable the fast spanning-tree mode for the selected port. In this mode, ports skip the Discarding and Learning states, and proceed straight to Forwarding.

•Since end-nodes cannot cause forwarding loops, they can be passed through the spanning tree state changes more quickly than allowed by standard convergence time. Fast forwarding can achieve quicker convergence for end-node workstations and servers, and also overcome other STA related timeout problems. (Remember that fast forwarding should only be enabled for ports connected to a LAN segment that is at the end of a bridged LAN or for an end-node device.)

•This command is the same as spanning-treeedge-port,and is only included for backward compatibility with earlier products. Note that this command may be removed for future software versions.

Example

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree portfast

Console(config-if)#

Related Commands

spanning-tree edge-port (4-144)

spanning-tree link-type

This command configures the link type for Rapid Spanning Tree. Use the no form to restore the default.

Syntax

spanning-tree link-type {auto point-to-point shared} no spanning-tree link-type

•auto - Automatically derived from the duplex mode setting.

•point-to-point- Point-to-point link.

•shared - Shared medium.

GSW-2692 specifications

The LevelOne GSW-2692 is an advanced Layer 2 Gigabit Ethernet switch that is designed to cater to the networking needs of both small and medium-sized enterprises. Highly regarded for its reliability and performance, the GSW-2692 offers 24 Gigabit Ethernet ports, enabling seamless and high-speed data transfers across connected devices. With its robust design and versatile capabilities, this switch has earned its place as an essential component in modern IT infrastructure.

One of the standout features of the GSW-2692 is its extensive support for advanced networking technologies. The switch includes support for IEEE 802.1Q VLAN tagging, which allows users to create separate virtual networks for improved traffic management and enhanced security. By segregating network traffic, businesses can optimize bandwidth usage and reduce congestion, contributing to overall increased network performance.

Additionally, the GSW-2692 supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), ensuring loop-free network topology. This capability is crucial in larger networking environments where multiple switches are interconnected, as it prevents broadcast storms and enhances network resilience. The switch also includes features such as port mirroring, which provides administrators with the capability to monitor network traffic in real-time for troubleshooting and analysis.

Power over Ethernet (PoE) support is another significant advantage of the GSW-2692. With PoE functionality, it enables the switch to deliver electrical power along with data to connected devices such as IP cameras, VoIP phones, and wireless access points, eliminating the need for additional power sources and simplifying installations.

In terms of physical characteristics, the LevelOne GSW-2692 is designed for efficient heat dissipation and features a fanless design, which ensures silent operation. Its desktop or rack-mountable options make it flexible for various installation environments. The switch also features a web-based management interface, which simplifies the configuration and monitoring processes, allowing for intuitive management of network settings.

Overall, the LevelOne GSW-2692 stands out as a feature-rich, reliable, and high-performance networking solution that meets the demands of modern enterprises. Its combination of advanced technologies, scalability, and ease of use makes it an excellent choice for businesses looking to enhance their network infrastructure.
