support direct access to G.703ITU's standard on physical and electrical characteristics of various digital interfaces, including 64kbps and 2.048Mbps interfaces, the G/V converter must be used. In branch nodes, high-end routers are generally not configured, and even low-end routers are several times more expensive than switches. Therefore, the layer-3 Switch Tec

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

to the native understanding, when a non-TAG port receives a data frame and contains a vlan id, make a judgment, if the vlan id is the PVID of the port, it can be received; otherwise, it is discarded. If the port that receives the data frame is a TAG port and the data frame is a common data frame, the default vlan id o

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

ICMP Echos to 192.168.20.1, timeout is 2 seconds: .!!!! Success rate is 80 percent (4/5), round-trip min/avg/max = 24/48/84 MS From the above, we can see that through the deployment of layer-3 switching technology, the host between VLANs can communicate with each other. This experiment is complete. [PL1]Disable layer

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

data processing. (1) Hardware-only layer-3 technology is relatively complex, costly, but fast, with good performance and strong load capabilities. The principle is to use an ASIC chip and hardware to search and refresh route tables. When the data is received by the port interface chip, first find the target MAC address in the

Layer-3 Switch Equipment is still quite common, So I studied how to identify the performance of layer-3 Switch Equipment. Here I will share with you, I hope it will be useful to you. With the gradual development of network applica
