Teldat’s Switching Technology Solution FAQ’s

Q: What is the fundamental difference between a Level 2 (L2) Switch and a Level 3 (L3) Switch?

Level 2 (L2) Switches operate at the data link layer of the OSI model and handle the switching of data frames based on MAC addresses. Level 3 (L3) Switches function at the network layer and are capable of routing packets based on IP addresses.

Q: What are Level 2+ (L2+) Switches, and what advantage do they offer?

Level 2+ (L2+) Switches can be considered a streamlined version of Level 3 Switches, as they possess the ability to carry out limited Level 3 switching functionalities. They allow for faster hardware processing for high-speed data flows and advanced features. L2+ switches also permit a high cost performance when required.

Q: What is the role of an Access Switch in a network environment?

Access switches are fundamental components that facilitate the connection of end-user devices, such as PCs, printers, phones, and other equipment, to the network. They often operate at Layer 2+ and are crucial for ensuring efficient communication within a Local Area Network (LAN).

Q: How do Distribution Switches fit into the network architecture?

Distribution switches are strategically positioned between access switches and core switches. They are critical for aggregating and managing network traffic, functioning at both Layer 2+ and Layer 3, and providing limited routing capabilities. This intermediate layer helps manage and optimize traffic flow within larger network segments.

Q: Why is Power over Ethernet (PoE/PoE+) considered an important feature for switches?

Devices connected to a switch via PoE/PoE+ simplify installations and provide flexibility, enabling devices (like IP cameras or phones) to be installed wherever required without needing to be near power outlets. This technology also permits centralized power management.

Q: What are VXLAN and VSU, and why are they important in core switches like the Windbit ESW4L3?

Virtual Extensible LAN (VXLAN) is used to provide scalability, ensuring performance in large environments. Virtual Switch Unit (VSU) ensures redundancy with high availability and failover capabilities, as well as synchronization to maintain consistent configurations for seamless operation of large switch scenarios. The Teldat Windbit ESW4L3 core switch works on both VXLAN and VSU.
