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

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 CrossBar-based core switch products. However, many products on the market still use gigabit p

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

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

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

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 viru

(Address Resolution) packet to the "Default Gateway, the IP address of the "Default Gateway" is actually a layer-3 Switch module. When host A sends an ARP request to the IP address of the "Default Gateway", if the layer-3 Switching Module knows the MAC address of host B dur

Switch module broadcasts an ARP request to Site B based on the route information. Site B receives the ARP request and then replies to the layer-3 Switch module with its MAC address, the layer-3 Switching Module saves the address

layer-2 switch. Currently, the price of a M L3 switch is only tens of thousands, which is similar to that of a high-end L2 Switch. Built-in security mechanism The layer-3
