3 Configuring the Switch

•Admin Edge Port – You can enable this option if an interface is attached to a LAN segment that is at the end of a bridged LAN or to an end node. Since end nodes cannot cause forwarding loops, they can pass directly through to the spanning tree forwarding state. Specifying Edge Ports provides quicker convergence for devices such as workstations or servers, retains the current forwarding database to reduce the amount of frame flooding required to rebuild address tables during reconfiguration events, does not cause the spanning tree to reconfigure when the interface changes state, and also overcomes other STA-related timeout problems. However, remember that Edge Port should only be enabled for ports connected to an end-node device.

•Admin Link Type – The link type attached to this interface.

-Point-to-Point – A connection to exactly one other bridge.

-Shared – A connection to two or more bridges.

-Auto – The switch automatically determines if the interface is attached to a point-to-point link or to shared media.

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.
