These two types of switches serve different functions, and each excels in particular environments. In this article, we’ll explore the key differences. Use cases, and help you determine the best choice for your network needs. >> Contents What is a Layer 2 Switch? What is a Layer 3 ...
Layer 2 Industrial Ethernet switches feature all functions required to construct a Layer 2 network. A distinction is made between two types — unmanaged Layer 2 and managed Layer 2 switches. Unmanaged Layer 2 switches can be integrated into a Layer 2 network without additional configuration. Managed...

Using an embedded processor also allow designers to implement any other high level networking functions such as Spanning Tree algorithm or any user specific task. The switch implement a programmable number of ports, which are physically implemented with Atlantic ports (Simple Master / Slave FIFO ...
Layer 2 Switching Methods LAN switches are characterized by the forwarding method that they support, such as a store-and-forward switch, cut-through switch, or fragment-free switch. In the store-and-forward switching method, error checking is performed against the frame, and any frame with ...
For example, when the NGFW Module is installed in slot 1 on the switch, the internal Ethernet interfaces used by the switch are XGE1/1/0/0 to XGE1/1/0/1. Eth-Trunk2 and Eth-Trunk3 are interfaces of the switches in the CSS. Deployment Solution The four interfaces connecting the ...
Optional routing functions on layer 3 permit communication between different IP subnetworks. SCALANCE XR-500 managed (Layer 3) For networking and structuring high-performance industrial networks and for connecting office networks to automation networks. As a Layer 3 switch, SCALANCE XR-500 is extremely...
It functions as a node in a PTP network and can be selected by the BMCA as a master or slave within a subdomain. These are the most common clock type on a PTP network because they are used as end nodes on a network t...
The Cisco SM-X Layer 2/3 EtherSwitch Service Module (Cisco SM-X Layer 2/3 ESM) integrates the Layer 2 and Layer 3 switching features and provides the Cisco 4451-X ISR the ability to use the Cisco SM-X Layer 2/3 ESM as an independent Layer 3 switch when running the Cisc...
If a switch then adds information to that frame, increasing the total size by 8 bytes, the 1,518-byte maximum-sized frame is now 1,526 bytes. VPLS Overhead The second piece of this puzzle is that the Ethernet frames (really Q-in-Q frames) are not being placed on the wire for ...
