  2. A Layer 3 switch is a special network device that has the functionality of a router and a switch combined into one chassis. It works in our network by simply allowing connected devices that are on the same subnet or virtual LAN (VLAN) to exchange information at lightning speed, just like a switch that operates in the data link layer of the OSI ...

    A Layer-2 switch works at the Data Link layer or Layer 2 of the OSI reference model. It especially utilizes MAC addresses to direct information packets between devices that are on the exact same network. 1. MAC Address Table:A Layer-2 switch will keep a MAC address table that identifies the MAC address of the connected device and the port number. T...

    A Layer-3 switch works at the third layer of the OSI mode and it has features of both a switch and a router. It employs IP addresses in the forwarding of packets and routing among one or different networks/subnets. Layer-3 switches are characterized by: 1. Routing Capabilities: Layer – 3 switches are different from Layer – 2 switches in that Layer ...

    Thus, Layer-2 and Layer-3 switchescan be defined in terms of their functional layers and activities. In simple LANnetwork which involves a basic level of network segmentation, Layer-2 switches are preferred while for more complex network especially those involving routing and inter VLAN, Layer-3 switches are preferred. A switch is therefore dictate...

  5. Mar 30, 2017 · A Layer 3 switch -- also referred to as a multilayer switch -- combines the duties of a switch and a router. It acts as a switch because it connects devices that are on the same IP subnet or virtual LAN , and it performs at or near wire speed.

  6. Jun 4, 2024 · The difference between a switch being a “Layer 2” switch and a “Layer 3” switch is whether it facilitates a routing function (routing happens at the “Internet Protocol” layer, or Layer 3 on the OSI model).

  7. Mar 29, 2022 · What is Layer 3 switch? Layer 3 switch is an Ethernet switch that switches packets by looking at both their network address (for example, their IP or IPX address) and their physical address (for example, their MAC address).

  8. Aug 9, 2023 · While a Layer 2 switch focuses on forwarding data frames between devices at the data link layer (Layer 2), a Layer 3 switch goes further. It can route IP packets between different subnets and perform advanced routing functions like policy-based routing and quality of service (QoS).
