Both layer-2 and layer-3 switches are end-to-end exchange processes based on port addresses. Although this MAC address and IP address-based switch technology can greatly improve the data transmission rate between nodes, however, it is impossible to

There are three types of Ethernet ports: Access, Hybrid, and Trunk. an Access port can belong to only one VLAN and is generally used to connect to a computer. A Trunk port can belong to multiple VLANs and receive and send packets from multiple VLANs,

On April 9, March this year, ruijie launched the core switch Newton18000 for cloud architecture network at the Global Strategy and product conference. It has top-level configuration, supports advanced virtualization and green and energy-saving

The Spanning Tree Protocol (Spanning Tree) is a layer-2 management protocol that selectively blocks redundant network links to eliminate L2 loops. It also supports link backup. Because the Spanning Tree Protocol itself is relatively small, it is not

Each Ethernet device has a unique MAC address at the factory. Why do I need to assign an IP address to each host? In other words, each host is assigned a unique IP address. Why should we embed a unique MAC address in the production of network

Before learning how to establish a neighbor relationship with OSPF, let's review the process of establishing a neighbor relationship with RIP. After router A running the RIP Protocol is started, it sends A request packet to the neighbor router B.

In our daily life, passwords are everywhere. QQ passwords, email passwords, and Windows logon passwords. For our network administrator, there must be one or more vro passwords. If the QQ password is forgotten, it can be recovered through password

A new smart installation system is developed for this vro to ensure the performance. A "one-click setting" Configuration Wizard CD is provided when you purchase a vro. When setting a vro, run the "one-click setting" Configuration Wizard. The

The development of wireless LAN is now very complete, and the speed is getting faster and faster. The current mainstream products not only achieve the speed of common wired Ethernet, but also have basic security assurance. More importantly, no

When you enter the office area of an enterprise or company and find an H3C MSR router on the table, there is no connection cable except a power cord, you may simply think that this router is only prepared to replace a device that has not been

The upgrade cycle in the computer field is getting shorter and shorter. Therefore, you should learn to upgrade network equipment to maximize investment utilization. I believe that many enterprise network administrators have upgraded servers and

Data encryption and decryption requires a large number of complex operations. The software processing code is executed by the CPU. If you use hardware encryption, the CPU does not need to participate, you can release valuable CPU resources for more

Network security is constantly increasing, so it is very urgent to encrypt data. How to prevent illegal users from accessing the wireless network, connecting your customers' computers, and obtaining privacy information. We need to know how to

The emergence of BT downloading Methods puts forward higher requirements on network devices. Its brute-force bandwidth grab capability affects the normal application of the network. In shared network environments such as the resident network and

The second layer of the router's bridging function is actually the ability to process data frames. When a vro enables a "sub-interface", multiple data frame encapsulation such as ISL and 802. 1Q are supported. In this way, we can use a router to

As a network engineer, it is necessary to deal with vrouters frequently. In the face of all kinds of routing problems, no one can say that they can do anything. Today, we will gather together various Routing Problems, hoping to help you. 1. When to
