broadcast storms due to the inability to divide broadcast domains.
Although traditional routers can be used to isolate broadcasts, their performance is not guaranteed. The performance of a layer-3 switch is very high. It provides both layer-3 routing and layer-2 switching n

The layer three switch configures the IP address for the interface. The use of SVI (Exchange Virtual Interface) to achieve inter-VLAN interconnecti
act as a route. It is a switch because it is extremely fast, almost reached the second-level switching speed. This is also the topic of this Article. What is layer-3 switching technology. Let's first introduce the OSI model, which is widely recognized as the Open System Interconnection Model OSI of the International Organization for Standardization (ISO). It is a hierarchical network architecture, divide a
With the development of China's routing industry and the wide application of L3 router switches, I have studied the benefits of choosing a l3 router switch. I will share with you here, I hope it will be useful to you. In addition to excellent performance, layer-3 route switches also have some features that traditional layer-2
Why is a layer-3 switch used?
1. layer-3 switching is indispensable for network backbone
To describe the role of a layer-3 Switch in many network devices, it is not described as a "mainstay. In campus networks and urban education networks, three-
A layer-3 Switch uses a new technology that combines layer-3 routing and layer-2 switching. If a large network is divided into small local networks by department, region, and other factors, the layer-3

for Route Selection and forwarding. Layer-3 switches use direct connection routes to achieve mutual access between different VLANs. Layer-3 switches configure IP addresses for interfaces and use SVI (exchange virtual interfaces) to interconnect VLANs. SVI refers to creating virtual interfaces for VLANs in a vswitch and configuring IP addresses.

Layer-3 switches are quite common, so I have studied the comprehensive analysis of the benefits of using layer-3 switches. Here I will share with you, hoping to help you. Layer-2 switches are based on mac addresses, frame layer-3 switches are based on IP addresses, and data
applicable to IP and IPX traffic, it also applies to IP address multiplexing and bridge traffic. Catalyst 2948G-L3 supports a high-performance architecture with 22 Gbps bandwidth. The Switched Optical Fiber supports all 48 10/100 ports and 2 gigabit uplink connections at a wire speed.
The Catalyst 2948G-L3 can be installed in a 1.5RU chassis and can be equipped with an optional external redundant power supply. It supports 22 Gbit/s shared memory, com

1. layer-3 switching is indispensable for network backbone
To describe the role of a layer-3 Switch in many network devices, it is not described as a "mainstay. In campus networks and urban education networks, three-layer switches are available in backbone networks, man backbone networks, and aggregation layers. In p
Basic Features: This article introduces the layer-3 Switch Technology for exact matching and query. It is very complicated for many people to discuss the technology of layer-3 switches interconnected between companies or large network connections of the company, this is confusing. Despite this, many people still need to understand the construction of
internal MAC address table. Speaking of exchange, in a broad sense, any data forwarding can be called exchange. However, the traditional and narrow layer-3 routing exchange technology only includes data link layer forwarding. Currently, layer-4 switching technology is mature. From the hardware point of view, the interface modules of the 2nd
10 standard layer-3 switch technology hotspots), layer-3 switches basically have all the functions of traditional switches. The layer-3 switches shall prevail. The specific technical implementation of switches includes distributed pipelines, dynamic and Scalable Memory.

So the IP-MAC binding on the second layer is invalid.
The forwarding mechanism of a layer-3 Ethernet switch is divided into two

There are many things worth learning about layer-3 switches. Here we will mainly introduce the future trend of layer-3 switch technology. From the current Ethernet switch market, there are many things worth learning. Here we mainly introduce the general situation, we can see that the M
In this comparison test, several products support layer-3 switching. In order to test its layer-3 performance, we use IXIA1600 and ScriptMate software to test throughput, latency, and other indicators, and test the layer-3 switching performance of several layer-3 switches under Static Routing.In this section, we will f

Host a and host B need to communicate. When the bridge receives data from host, determine whether A and B are in the same LAN Based on the MAC address and an address table maintained by the bridge software. If A and B are in the same
