Which source of data does l3 network device use to make its l3 decisions?
Industrial network switches form the basis of several high speed data networks. These switches are used to connect different devices in a network, and thus are one of the important requirements. The network communications are described in the Open System Interconnect (OSI) model. This model operates on seven layers: Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and Physical Layer. The layer 2 managed switch operate on the data link layer and the layer 3 switch on the network layer. Among these, layer 2 switches are one of the key requirements for any high speed network. As the converged networks grow in size, and density of data networks increases, the demand for layer 3 switches increases, too. This article explores these two switch types, their typical features, and their applications in modern data networks. Show
What are Layer 2 and Layer 3 Networking Switches?The following pointers will help you understand the basic difference between layer 2 and layer 3 switches.
In recent years, layer 2 managed switches and layer 3 managed switches have gained immense popularity. Of these, the layer 2 managed switches are used in applications wherein the switch forwards the traffic between the network hosts located in the same subnet. For instance, it may forward the traffic between the client PC and the server in the same network. This transmission is made on the basis of the MAC table. Layer 3 switches are used if the client PC and the server are located in different subnets. The network transmission decision is made based on the map of the IP network present in its routing table. What are the Different Features of Layer 2 and Layer 3 Switches?Here are some differentiating features of both the network layers.
What are the Applications of Layer 2 and Layer 3 Switches?
ConclusionAs the difference between layer 2 switches and layer 3 switches is now clear, it is important to invest in quality switches to support high speed data networks in your organization. Today, you can see several manufacturers specializing in layer 2 managed switches, layer 2 smart switches, and layer 3 switches. However, not all may serve your purpose. VERSITRON is one of the leading manufacturers of layer 2 and layer 3 network switches.

Data at this layer is referred to as a packet, which is a stateless grouping of data. Devices that forward packets do not validate that the other end receives the data.
How does L3 switch work?A Layer 3 switch is basically a switch that can perform routing functions in addition to switching. A client computer requires a default gateway for layer 3 connectivity to remote subnets.
What makes decisions based on Layer 3 addresses?Whereas switches and bridges make forwarding decisions base on Layer 2 MAC addresses, a router makes forwarding decisions based on Layer 3 addresses.
What is the main protocol used for addressing at L3?The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks--hence, the name internet. It is an encapsulating protocol similar to the way Ethernet is an encapsulating protocol.
