What is the role of ASICs in a multilayer switch?

Layer 2 switching is hardware-based, which means switches use application-specific integrated circuit (ASICs) to build and maintain the Forwarding information base and to perform packet forwarding at wire speed.

What is the function of ASICs in a?

ASICs have gained relevance from the demonstration of their role in sensory processes in the visual system, hearing, balance, touch, nociception, olfaction, and taste, in addition to their important participation in synaptic transmission.

What is an ASIC on a switch?

The ASIC, or Application Specific Integrated Circuit, is a special purpose sillicon chip. The ASIC achieves high forwarding speeds as packets pass through the forwarding plane. An ASIC in a general sense is not unique to networking. Many electronic devices use them for some specific purpose.

What is an example of a multilayer switch?

An example would be the way Cisco Express Forwarding (CEF) can directly forward packets between hosts. This is possible because both the source and destination MAC and IP addresses are known. A quick inspection of the packet can determine if it is multilayer switch ready.

What is the benefit of multilayer switch over a Layer 2 switch?

As a traditional switch, it can inspect frames. While multilayer switches not only can do all the job that Layer 2 switches do, it has routing function as well, including static routing and dynamic routing. So multilayer switches can inspect deeper into the protocol description unit.

What statement is true regarding a multilayer switch?

Which statement is true regarding a multilayer switch? A multilayer switch provides the functionality of layer 2 and layer 3 giving port density and connectivity to end devices while also providing the ability to route traffic and bridge logical networks.

How do I know if my switch is layer 2 or 3?

Layer 2 vs Layer 3 switches Devices in an Ethernet network are identified by a MAC (media access control) address, which is generally hardcoded to a particular device and doesn’t normally change. Layer 3 is the network layer and its protocol is the Internet Protocol or IP.

What is the main difference between a Layer 2 switch and a multilayer switch?

The layer 2 and Layer 3 differs mainly in the routing function. A Layer 2 switch works with MAC addresses only and does not care about IP address or any items of higher layers. Layer 3 switch, or multilayer switch, can do all the job of a layer 2 switch and additional static routing and dynamic routing as well.

What is a multilayer switch (MLS)?

Unsourced material may be challenged and removed. A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers .

What are the advantages of multi-layer switching?

Multi-layer switching can move traffic at wire speed and also provide layer 3 routing. There is no performance difference between forwarding at different layers because the routing and switching is all hardware based – routing decisions are made by specialized ASIC with the help of content-addressable memory.

What are the characteristics of an access layer switch?

The port density of a switch (the number of ports available on a single switch), forwarding rate (how much data the switch can process per second), and Power over Ethernet (the ability of the switch to deliver power to a device over the existing Ethernet cabling) are access layer switch features to be considered when designing a network.

What is layer 4 switching and how does it work?

Layer 4 switching provides additional datagram inspection by reading the port numbers found in the transport layer header to make routing decisions (i.e. ports used by HTTP, FTP and VoIP ). These port numbers are found in RFC 1700 and reference the upper-layer protocol, program, or application.
