interconnected with layer-3 switches. When using a router to connect to a vrovlan, you generally need to set sub-interfaces corresponding to each VLAN on the LAN Interface, while a layer-3 Switch generates a "VLAN Interface" internally )". A VLAN interface is an interface u

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 CrossBar-based core switch products. However, many products on the market still use gigabit port interconnection, it is mainly intended for

How to select a layer-3 SwitchAt present, layer-3 switches are showing a strong growth trend and are replacing routers in Lan. Their huge market potential is attracting a large number of domestic and foreign manufacturers to join the competition. Fortunately, Chinese manufacturers have developed their own ASIC chips an

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 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 o

only supports full duplex of Mb, the maximum rate that the switch and customer can automatically negotiate with each other. You can hard-code the process during vswitch initialization to save time. However, this is not always a good choice, because it may not know how fast the client supports. This adaptive time is not long, so consider whether it is worthwhile to perform hard encoding on each vswitch port. Now we have reviewed the different phases o

A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the

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

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

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

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

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

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

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
