cisco layer 3 switch models

CrossBar technology, two types of layer-3 switching chips are generally used: one is an exchange chip that can generate Gigabit and MB ports; one is a CrossBar chip that only outputs Internal High-Speed interfaces (usually at a rate of over 10 Gbit/s) for interconnection between modules. Currently, Cisco, Extreme,, gangwan, and other vendors have launched CrossB

Gbit/s) for interconnection between modules. Currently, Cisco, Extreme,, gangwan, and other vendors have launched CrossBar-based core switch products. However, many products on the market still use gigabit port interconnection, it is mainly intended for users with high performance requirements and high price sensitivity. 2. Access Control Based on hardware line rate As the number of users in the network in

There are many things worth learning about layer-3 switches. Here we mainly introduce the development status of the new technology in layer-3 switches. The physical connection from the line card to the switch structure in the shared switching architecture is simplified to a

3.12 layer-3 Switching Purpose: 1. master the basic configurations of layer-3 switching for inter-VLAN communication. 2. Understand the implementation principle of layer-3 switching. Tutorial topology: 650) this. width = 650; "sr

bound together, multiply the bandwidth of the link. Link aggregation technology can achieve load balancing of different ports, and also backup each other to ensure link redundancy. In some Gigabit Ethernet switches, a maximum of four link aggregation groups are supported, and each group has a maximum of four ports. Both the Spanning Tree Protocol and link aggregation can ensure the redundancy of a network. Set redundant links in a network and use the Spanning Tree Protocol to block the backup l

The security switch mainly uses the access control list to implement the security function of the packet filtering firewall. It enhances the security protection capability and is the first choice for small and medium-sized enterprises. Vswitches play an important role in the enterprise network, usually the core of the entire network. In the network era where hackers are intruding into the cloud and the virus is raging, the core security

packet forwarding rate of A vswitch can reach over mpps, And the backboard bandwidth can be up to 32 Gbps. It can be seen that the data processing capability of layer-3 switches is much higher than that of routers. ◆ Supports multiple protocols. Like routers, layer-3 switches support multiple network protocols such as

Since Layer-3 switches can be considered as composed of routers and common switches, You can first try to install some modules with routing functions during assembly, in this way, there is a layer-3 Switch rich in routing functions. Its functions are equally powerful. Recent

Beginner: I learned about the basic features of a layer-3 Switch. Some time ago, my colleagues asked me questions about the basic features of the layer-3 Switch. At that time, I did not give a positive answer, I was also the first

four Gigabit Links can be bound together, multiply the bandwidth of the link. Link aggregation technology can achieve load balancing of different ports, and also backup each other to ensure link redundancy. In some Gigabit Ethernet switches, a maximum of four link aggregation groups are supported, and each group has a maximum of four ports.

Since Layer-3 switches can be considered as composed of routers and common switches, You can first try to install some modules with routing functions during assembly, in this way, there is a layer-3 Switch rich in routing functions. Its functions are equally powerful. Recent

Layer-3 switches are quite common, so I have studied the comprehensive description of layer-3 switch technology. Here I will share it with you and hope it will be useful to you. The emergence of layer-

A device with layer-3 switching is a layer-2 switch with layer-3 routing, but it is an organic combination of the two, it is not simply to overlay the hardware and software of a router device on a LAN

Experiment on single-arm routing using a layer-3 Switch In the real environment, sometimes the gateway is not necessarily enabled on the router, sometimes the single-arm routing function is not necessarily connected to the interface on the router, you can use a layer-3

In order to help enterprise users better understand the meaning of layer-3 Switch, understand the various new technologies supported by the leading layer-3 switch in the current market, and their position and role in the next-gene

Have you ever thought about manually creating a layer-3 switch? Here we will teach you how to create such a layer-3 switch, which is equally powerful. Recently, the price of vswitches has been greatly reduced. Some

Layer-3 switches are quite common. So I studied the introduction and Application Analysis of layer-3 switches. Here I will share with you, hoping they will be useful to you. A vswitch is the "cornerstone" for building a network platform, also known as a network switch. It is

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

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
