Interpreting L2 Ethernet ports and link types with experience
L2 Ethernet port
Vswitches include Access, Trunk, Hybrid, and QinQ layer-2 Ethernet ports. In this section, the Ethernet ports
What is a vswitch port? What is the role of the vswitch port? Vswitches cannot play their role in optimizing network performance. After reading this article, you will surely have a lot of GAINS. I hope this article will teach you more.
In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traffic analysis, and intru
The most important function of a vswitch is to speed up the fast data forwarding in a large local area network. The routing function is also used for this purpose, so the switch port issue is also very important, it is really not easy to set a vswitch port.
In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traff
Abstract:
In view of the slow transmission speed and difficult network connection of traditional devices, a Data Conversion System for serial ports and Ethernet is proposed using w5300 and c8051f120 single chip microcomputer. the RS232 and RS485 chips are used to receive and send low-speed serial data, the single-chip microcomputer c8051f120 is used as the core processing chip, and the w5300 chip is used t
For details about how to identify the extended serial port-Linux general technology-Linux technology and application information when installing centos on a multi-serial motherboard, refer to the following section. I bought a multi-serial control board with Intel Atom D525 CPU. It is estimated that multiple serial ports are extended through the PCI-e bus. After CentOS is installed, you cannot identify the e

Because smart switching performs simultaneous data exchange on most ports, it requires a wide switching bus bandwidth. If a layer-2 switch has N ports, multiple Access ports and low prices provide a perfect solution for small network users.
In order to ensure the key services of users and treat users of different level

To monitor the performance of mysqlserver, it is estimated that many people use the mysql-cacti-templates template in cacti, but its default configuration only supports monitoring of the standard mysql3306 port. In fact, its script supports multiple ports, but the configuration in the template is not supported by default. The script parameters are as follows: Usage: phpss_get_mysql_stats
